Description

SYSTEMS FOR AMPLIFICATION OF AAV CAP PROTEIN CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Provisional Application No.63/542,480, filed on October 4, 2023; U.S. Provisional Application No.63/536,899, filed on September 6, 2023; U.S. Provisional Application No.63/522,304, filed on June 21, 2023; U.S. Provisional Application No.63/437,562, filed on January 6, 2023; and U.S. Provisional Application No.63/427,040, filed on November 21, 2022, the disclosures of which applications are herein incorporated by reference in their entirety. INTRODUCTION [0002] Recombinant adeno-associated virus (rAAV) is the preferred vehicle for in vivo gene delivery. AAV has no known disease associations, infects dividing and non-dividing cells, rarely if ever integrates into the mammalian cell genome, and can persist essentially for the lifetime of infected cells as a transcriptionally active nuclear episome. The FDA has recently approved several rAAV gene therapy products and many other rAAV-based gene therapy and gene editing products are in development. [0003] The most widely used method for producing rAAV virions is based on the helper-virus- free transient transfection of multiple plasmids, typically a triple transfection, into adherent cell lines. Although there is ongoing investment to increase production capacity, current AAV manufacturing processes are inefficient and expensive. In addition, they result in variable product quality, with low levels of encapsidation of a payload, such as a therapeutic payload. There is, therefore, a need for improved methods for producing rAAV. SUMMARY [0004] The polynucleotides, polynucleotide constructs, vectors, and system thereof, plasmids, and cells, such as, cell lines stably integrated with the polynucleotides, polynucleotide constructs, vectors, and system thereof, plasmids provided herein enable increased production of recombinant AAV (rAAV) virions. [0005] The increased production of rAAV is hypothesized to be achieved by providing an overall increase in the levels of AAV capsid proteins. In one embodiment, the increase in levels of AAV capsid proteins is achieved by including a strong polyadenylation (polyA) signal sequence 3’ to the sequence encoding the AAV capsid proteins. In another embodiment, the increase in levels of AAV capsid proteins is achieved by using an inducible promoter to drive expression of capsid proteins which inducible promoter is stronger than the native promoter controlling expression of AAV capsid proteins. In a further embodiment, the increase in levels of AAV capsid proteins is achieved by including a strong polyadenylation (polyA) signal sequence 3’ to the sequence encoding the AAV capsid proteins and by using an inducible promoter to drive expression of capsid proteins which inducible promoter is stronger than the native promoter controlling expression of AAV capsid proteins. In another embodiment, the increase in levels of AAV capsid proteins is achieved by using two separate polynucleotide constructs each encoding AAV capsid proteins, one under the control of the native promoter and another under the control of an inducible promoter. One or more of these embodiments can also be combined to further increase capsid proteins expression and enable increased production of recombinant AAV (rAAV). [0006] In certain embodiments, the polynucleotide constructs may be introduced into cells, e.g., stably integrated into the nuclear genome of the cells and used to express components for formation of rAAV in an inducible manner thereby avoiding the toxicity of AAV Rep proteins and AAV Cap proteins when constitutively expressed. Methods for generating such cells and cell lines useful for producing rAAV and methods for producing rAAV from the cells and the cell lines are also disclosed.

BRIEF DESCRIPTION OF THE DRAWINGS [0073] FIG.1A depicts an exemplary system of polynucleotides for inducibly producing rAAV. In absence of first and second triggering agents, the system is in an off state. This system includes Construct 1, Construct 3, Construct 4, and Construct 2, and is referred to as v1.2 system. The v1.2 system is distinct from the v1.0 system in that the v1.2 system comprises a recombinant nucleic acid that expresses Cap protein driven by an inducible promoter (see, e.g., Construct 2). In this schematic, which depicts an exemplary v1.2 system, Construct 1 and Construct 2 are two separate polynucleotides which are configured for inducibly expressing AAV capsid proteins. Construct 1, in addition to inducibly expressing AAV Cap proteins also inducibly expresses full-length AAV Rep proteins, and both AAV Cap proteins and AAV Rep proteins are driven by their native promoters (p40, and p5 and p19, respectively). [0074] FIG.1B depicts the post-triggered state (also referred to as the on state) of Constructs 1- 4 shown in FIG.1A following the addition of the first triggering agent, doxycycline, and the second triggering agent, tamoxifen. The Cre coding element is positioned between LoxP sites and is additionally fused to estrogen response elements (“ER2”), which allows for control over the localization of Cre in response to estrogen agonists, such as tamoxifen. Upon addition of a first triggering agent, e.g., doxycycline, Cre is expressed, and upon addition of the second triggering agent, e.g., tamoxifen, Cre translocates to the nucleus. Following translation and translocation of the Cre protein into the cell nucleus, the Cre protein effects excision of its own coding sequence, leaving the integrated constructs as shown in FIG.1B. Therefore, adenoviral E2A and E4 helper proteins are expressed. Cre also excises out the excisable element flanked by LoxP sites in Construct 1, allowing AAV rep and cap coding sequences expression under control of native promoters. rAAV virions encapsidating the payload, such as a GOI, are therefore produced. [0075] FIG.2A depicts an exemplary system of polynucleotides for inducibly producing rAAV, which is also an exemplary v1.2 system. In absence of a first triggering agent, e.g., doxycycline, and a second triggering agent, e.g., tamoxifen, the system is in an off state. In Construct 1 of this schematic, the sequence encoding the AAV Cap proteins is operably linked to an inducible promoter (for example, Tet-On promoter). This is different from the v1.0 system in which the AAV Cap proteins are expressed under the control of a native AAV promoter. In this v1.2 system, the coding sequences for the Rep and Cap proteins are oriented in opposite directions such that the internal p40 promoter in Rep coding sequence which controls expression of the Cap proteins is spatially separated from the Cap coding sequence and does not control Cap proteins expression. The inducible promoter (for example, Tet-On promoter) controlling the expression of the Cap proteins is stronger than the native p40 promoter, resulting in increased Cap proteins expression as compared to the v1.0 system. The coding sequences and promoters for the Rep proteins are separated from the coding sequence and the inducible promoter for the Cap proteins by a transcription blocking element (TBE). This construct may also be referred to as a Rep-Cap construct. [0076] FIG.2B depicts the on state of the system of polynucleotides for inducibly producing rAAV depicted in FIG.2A, after induction by a first triggering agent, e.g., doxycycline, and a second triggering agent, e.g., tamoxifen. The Cre coding element is positioned between LoxP sites and is additionally fused to estrogen response elements (“ER2”), which allows for control over the localization of Cre in response to estrogen agonists, such as tamoxifen. Upon addition of a first triggering agent, e.g., doxycycline, Cre is expressed and Cap proteins are expressed, and upon addition of the second triggering agent, e.g., tamoxifen, Cre translocates to the nucleus. Following translation and translocation of the Cre protein into the cell nucleus, the Cre protein effects excision of its own coding sequence, leaving the integrated constructs as shown in FIG.2B. Therefore, adenoviral E2A and E4 helper proteins are expressed. Cre also excises out the excisable element flanked by LoxP sites in Construct 1, allowing AAV rep coding sequences expression under control of native promoters. rAAV virions encapsidating the payload, such as a GOI, are therefore produced. [0077] FIG.3A shows an exemplary system of polynucleotides for inducibly producing rAAV, which is also an exemplary v1.2 system. In absence of a first triggering agent and a second triggering agent, the system is in an off state. In Construct 1 of this schematic, the sequence encoding the AAV Cap proteins is operably linked to an inducible promoter (for example, Tet- On promoter). The coding sequences and promoters for the Rep proteins are separated from the coding sequence and inducible promoter for the Cap proteins by a transcription blocking element (TBE). This system includes an additional polynucleotide, depicted as Construct 4, for expressing AAV Cap proteins driven by an inducible promoter. Construct 4 may be referred to as a Cap construct and is the same as Construct 2 shown in FIGs.1A and 1B. [0078] FIG.3B depicts the on state of the system of polynucleotides for inducibly producing rAAV depicted in FIG.3A, after induction by the agents, e.g., doxycycline, and a second triggering agent, e.g., tamoxifen. The Cre coding element is positioned between LoxP sites and is additionally fused to estrogen response elements (“ER2”), which allows for control over the localization of Cre in response to estrogen agonists, such as tamoxifen. Upon addition of a first triggering agent, e.g., doxycycline, Cre is expressed and Cap proteins are expressed, and upon addition of the second triggering agent, e.g., tamoxifen, Cre translocates to the nucleus. Following translation and translocation of the Cre protein into the cell nucleus, the Cre protein effects excision of its own coding sequence, leaving the integrated constructs as shown in FIG. 2B. Therefore, adenoviral E2A and E4 helper proteins are expressed. Cre also excises out the excisable element flanked by LoxP sites in Construct 1, allowing AAV rep and cap coding sequences expression under control of native promoters. rAAV virions encapsidating the payload, such as a GOI, are therefore produced. [0079] FIG.4 shows an exemplary method for generating a pool of P2 cell clone that includes Construct 3 configured to express Adenovirus helper proteins, Construct 1 configured to express AAV Rep and Cap proteins and Construct 4 to express a payload (GOI, e.g., GFP or progranulin). Constructs 1, 3, and 4 are those depicted in FIG.1A. [0080] FIG.5 shows an exemplary method for generating a P3 cell pool from the P2 cell pool by introducing a polynucleotide (e.g., Construct 2, as depicted in FIG.1A) that encodes for AAV Cap proteins “T231 (P3)” into the P2 polyclonal cell pool of FIG.4. A polynucleotide that does not encode for AAV Cap proteins is used as a control to generate “T232 (P3)”. [0081] FIG.6 provides data for the titer of AAV Capsid proteins (Capsid Titer) and encapsidated payload, progranulin (PGRN), (PGRN titer) produced in T231 (P3) and T232 (P3) cells. Also shown is a table depicting percent packaging of the gene encoding PGRN for T231 (P3) cells and T232 (P3) cells. [0082] FIG.7 depicts an exemplary v1.2 system of polynucleotide Constructs 1, 2, 3, and 4 that includes a first polynucleotide for encoding AAV Cap proteins under the control of the native promoter, p40, (see Construct 1) and a second polynucleotide for encoding AAV Cap proteins (Construct 2) under the control of an inducible promoter to achieve an overall increase in AAV Cap proteins expression as compared to a system of constructs that includes only the first polynucleotide for encoding AAV Cap proteins under the control of the native promoter, p40 (e.g., only Construct 1 and not including Construct 2). [0083] FIG.8 provides a schematic summarizing induction of cells that include the v1.2 system of polynucleotides “v1.2 cells” and characterization of the Capsid levels, excision kinetics for production of AAV Rep and Cap, GOI levels, and levels of encapsidated GOI. [0084] FIG.9 provides a timeline from the point of induction of cells with addition of tamoxifen and doxycycline (T=0) through 96 hours post-induction (T=96 hours). Expression of a protein marker, blue fluorescent protein, encoded by Construct 1 prior to the induction in v1.2 cells (T231) is measured and compared to a single cell clone generated after introduction and selection for integration of Construct 3 into viral producing cells and subsequent selection for that clone (T177CL9). Presence of the additional polynucleotide Construct 2 does not impact excision of the gene encoding BFP such that AAV Rep and Cap proteins can be expressed. [0085] FIG.10 provides data for characterization of rAAV produced by v1.2 cells and v1.0 cells. The ratio of “encapsidated GOI/total GOI” in v1.2 cells was measured and compared to the ratio of “encapsidated GOI/total GOI” in v1.0 cells. Fig.10 shows that in v1.0 cells, the production of genome of interest (GOI) is higher than Capsid production, indicating that capsid production could be a rate limiting step for producing encapsidated GOI (e.g., a payload). Increased capsid production in the V1.2 cells resulted in increased generation of rAAV. [0086] FIG.11 shows a time course of production of viral particles over a 7-day period after induction of v1.2 (pool) and v1.0 (clone) cells with tamoxifen and doxycycline. v1.2 cells produce viral particles that encapsidate a gene for expressing PRGN while v1.0 cells produce viral particles that encapsidate a gene for expressing green fluorescent protein (GFP). In FIG.11, the expression of capsids was measured (vp/ml). [0087] FIG.12 shows a time course of production of viral particles over a 7-day period after induction of v1.2 (pool) and v1.0 (clone) cells with tamoxifen and doxycycline. v1.2 cells produce viral particles that encapsidate a gene for expressing PGRN while v1.0 cells produce viral particles that encapsidate a gene for expressing green fluorescent protein (GFP). In FIG. 12, encapsidated GOI (either the gene for expressing PGRN or the gene for expressing GFP) was measured (vg/ml). [0088] FIG.13 shows high titer produced after induction of v1.2 cells from the T231 stable cell pool wherein the payload is progranulin (“v1.2 Pool (PGRN)”). The graph shows the capsid titer (vp/ml) from cell lysate produced after induction of v1.2 Pool (PGRN) cells compared to after induction of a v1.0 stable cell line pool wherein the payload is progranulin (“v1.0 Pool (PGRN)”), compared to after induction of a v1.0 stable cell line pool wherein the payload is eGFP (“v1.2 Pool (eGFP)”), and compared to after transient transfection of cells wherein the payload is eGFP (“Transient Transfection (eGFP)”). The v1.2 Pool (PGRN) cells show a greater than 10-fold improvement in viral titer over Transient Transfection (eGFP) titer and improvement in viral titer over both v1.0 Pool (PGRN) titer and v1.0 Pool (eGFP) titer. [0089] FIG.14A shows high capsid titer produced after induction of v1.2 pool cells wherein the payload is progranulin (v1.2 Pool (PGRN)) and after induction of v1.2 single cell clones wherein the payload is progranulin (v1.2 Clones (PGRN)). The v1.2 Pool (PGRN) capsid titer and v1.2 Clones (PGRN) capsid titer are higher than the v1.0 stable pool cells wherein the payload is eGFP (v1.0 eGFP Pool) capsid titer, v1.0 single stable cell clones wherein the payload iseGFP (v1.0 eGFP clones) capsid titer, v1.0 stable pool cells wherein the payload is progranulin (v1.0 PGRN Pool) capsid titer, and v1.0 single stable cell clones wherein the payload is progranulin (v1.0 PGRN Clones) capsid titer, indicating the v1.2 stable cells have successfully increased capsid titer >2 log. [0090] FIG.14B shows high vector genome production after induction of v1.2 pool cells wherein the payload is progranulin (v1.2 Pool (PGRN)) and after induction of v1.2 single cell clones wherein the payload is progranulin (v1.2 Clones (PGRN)). The v1.2 Pool (PGRN) vector genome titer and v1.2 Clones (PGRN) vector genome titer are higher than the v1.0 stable pool cells wherein the payload is eGFP (v1.0 eGFP Pool) vector genome titer, v1.0 single stable cell clones wherein the payload iseGFP (v1.0 eGFP clones) vector genome titer, v1.0 stable pool cells wherein the payload is progranulin (v1.0 PGRN Pool) vector genome titer, and v1.0 single stable cell clones wherein the payload is progranulin (v1.0 PGRN Clones) vector genome titer, indicating the v1.2 stable cells have successfully increased vector genome titer. [0091] FIG.15 shows the parent cell line is T205 CL23 (Top clone from stable cells v1.0 pool, in which the payload is progranulin). T318 was generated from T205 CL23 clone that has integrated the sequence for Tet inducible capsid (Construct 2 of FIG.1A) and selected based on hygromycin-resistance to make a v1.2 pool. Selecting a top clone with v1.0 system integrated in the genome and introducing Construct 2 into the top clone provides for increased vector genome titer and capsid titer as compared to introducing Construct 2 into a pool of clones with v1.0 system integrated in the genome. [0092] FIG.16 depicts an exemplary v1.0 system in the pre-triggered state. Cap proteins are expressed under the control of a native AAV p40 promoter. The brackets in construct 3 indicate the position of the flanking ITRs. V1.0 system is described in U.S. Patent Application Publication No.2022/0145328 which is incorporated herein. V1.0 cells are a pool of cells or a cell line that includes the constructs of the V1.0 system. DETAILED DESCRIPTION [0093] To solve the problems associated with low rAAV titers, disclosed herein are polynucleotide constructs and cells, such as, cell lines stably integrated with the polynucleotide constructs that enable increased production of recombinant AAV (rAAV) virions. The increased production is hypothesized to be achieved by providing an overall increase in the levels of capsid proteins which in turn increases production of rAAV. In one embodiment, the increase in levels of AAV capsid proteins is achieved by including a strong polyadenylation (polyA) signal sequence 3’ to the sequence encoding the AAV capsid proteins In one embodiment, the increase in levels of capsid proteins is achieved by using an inducible promoter to drive expression of capsid proteins. In a further embodiment, the increase in levels of AAV capsid proteins is achieved by including a strong polyadenylation (polyA) signal sequence 3’ to the sequence encoding the AAV capsid proteins and by using an inducible promoter to drive expression of capsid proteins which inducible promoter is stronger than the native promoter controlling expression of AAV capsid proteins. In another embodiment, the increase in levels of capsid proteins is achieved by using two separate polynucleotide constructs each encoding AAV capsid proteins, one under the control of a native promoter and another under the control of an inducible promoter. One or more of these embodiments can also be combined to increase capsid proteins expression and enable increased production of recombinant AAV (rAAV). [0094] In certain embodiments, the polynucleotide constructs may be stably integrated into the nuclear genome of the cells and may express components for formation of rAAV in an inducible manner thereby avoiding the toxicity of AAV Rep protein when constitutively expressed. 1.1. Definitions [0095] Unless defined otherwise, all technical and scientific terms used herein have the meaning commonly understood by one of ordinary skill in the art to which the invention pertains. [0096] The term "about", particularly in reference to a given quantity, is meant to encompass deviations of up to plus or minus five percent. [0097] "AAV" is an abbreviation for adeno-associated virus, and may be used to refer to the virus itself or derivatives thereof. The term covers all subtypes and both naturally occurring and recombinant forms, except where required otherwise. The components of the AAV DNA genome consist of two open reading frames, Rep and Cap, flanked by two 145 base inverted terminal repeats (ITRs). Rep gene encodes multiple distinct proteins including Rep78, Rep68, Rep52, and Rep40. These proteins are also referred to herein as Rep proteins or Rep and may encompass one or more of Rep78, Rep68, Rep52, and Rep40 and functional variants thereof and homologs thereof. Rep78 and Rep68 and functional variants thereof and homologs thereof are referred to herein as large Rep. Rep52, and Rep40 and functional variants thereof and homologs thereof are referred to herein as small Rep. Rep proteins from an AAV of a particular serotype may also be referred to as Rep1, Rep2, etc. where the Rep protein is derived from an AAV1 or an AAV2 serotype, respectively. Cap gene encodes capsid proteins VP1, VP2, and VP3 required for production of rAAV capsids. These proteins are also referred to herein as Cap proteins or Cap and may encompass one or more of VP1, VP2, and VP3 and functional variants thereof and homologs thereof. Cap proteins from an AAV of a particular serotype may also be referred to as Cap1, Cap2, Cap4, etc. where the Rep protein is derived from an AA1, an AAV2, or an AAV5 serotype, respectively. In addition to Rep and Cap, AAV requires a helper plasmid containing genes from a helper virus such as adenovirus, including E1a, E1b, E4, E2a, and VA genes for AAV replication. [0098] "Recombinant", as applied to an AAV virion, means that the rAAV virion (synonymously, rAAV virus particle) is the product of one or more procedures that result in an AAV particle Construct that is distinct from an AAV virion in nature. The procedure may be genetic alteration, e.g., by the addition or insertion of a heterologous nucleic acid Construct into the virus. [0099] "Recombinant virus" is meant to describe a virus that has been genetically altered, e.g., by the addition or insertion of a heterologous nucleic acid construct into the virus. [0100] The abbreviation "rAAV" refers to recombinant adeno-associated virus, also referred to as a recombinant AAV vector (or "rAAV vector"). The term “AAV” includes any AAV serotype as well as AAV vectors based on the combination of different serotypes (also referred to as "hybrid AAV vectors" or "pseudotype AAV vectors"). AAV serotype may be AAV type 1 (AAV-1), AAV type 2 (AAV-2), AAV type 3 (AAV-3), AAV type 4 (AAV-4), AAV type 5 (AAV-5), AAV type 6 (AAV-6), AAV type 7 (AAV-7), AAV type 8 (AAV-8), AAV type 9 (AAV-9), AAV type 10 (AAV-10), AAV type 11 (AAV-11), avian AAV, bovine AAV, canine AAV, equine AAV, primate AAV, non-primate AAV, ovine AAV, AAV-7m8, AAV-6.2, AAV- Dj, AAV-DJ/8, AAV2-retro, AAV2-QuadYF and AAV2.7m8, AAV-PHP.B, AAV-PHP.B2, AAV-PHP.B3, AAV-PHP.A, AAV-PHP.eB, AAV-PHP.eS, evolved capsids that are less immunogenic to mice and humans, and variants thereof and combinations thereof. “Primate AAV” refers to AAV isolated from a primate, “non-primate AAV” refers to AAV isolated from a non-primate mammal, “bovine AAV” refers to AAV isolated from a bovine mammal (e.g., a cow), etc. An "rAAV vector" comprises a polynucleotide sequence not of AAV origin (i.e., a polynucleotide heterologous to AAV), typically a polynucleotide sequence of interest for introducing into a target cell. In general, the heterologous polynucleotide is flanked by at least one, and usually by two AAV inverted terminal repeat sequences (ITRs). The heterologous polynucleotide can also be referred to as a polynucleotide payload. The term rAAV vector encompasses both rAAV virions and rAAV vector plasmids. [0101] An "AAV virus" or "AAV viral particle" or "rAAV vector particle" refers to a viral particle composed of at least one AAV capsid protein (typically by all of the capsid proteins of a wild-type AAV) and an encapsidated polynucleotide rAAV vector. If the particle comprises a heterologous polynucleotide (i.e., a polynucleotide other than a wild-type AAV genome, such as a transgene to be delivered to a mammalian cell), it is typically referred to as an "rAAV vector particle" or simply an "rAAV vector". Thus, production of a rAAV particle necessarily includes production of a rAAV vector, as such a vector contained within an rAAV particle. [0102] "Packaging" refers to a series of intracellular events that result in the assembly, encapsidation, and production of an AAV particle. [0103] AAV "rep" and "cap" genes refer to polynucleotide sequences encoding replication and capsid proteins of adeno-associated virus. AAV rep and cap are referred to herein as AAV "packaging genes." [0104] By "AAV Rep coding region" or “sequence encoding one or more Rep proteins” or “Rep encoding sequence” and grammatical equivalents thereof is meant the art-recognized region of the AAV genome which encodes the replication proteins of the virus which are required to replicate the viral genome and/or a payload flanked by ITRs. The rep coding region, as used herein, may be derived from any viral serotype, such as those described above. The region need not include all of the wild-type genes but may be altered, e.g., by the insertion, deletion or substitution of nucleotides, so long as the rep genes provide for expression Rep proteins. Rep coding sequences are further described below. The terms “AAV Rep coding sequence” and “AAV Rep proteins coding sequence” are used interchangeably herein. The terms “AAV Rep proteins”, “Rep proteins”, “AAV Rep polypeptide”, and “Rep polypeptide” are interchangeably used herein. [0105] By "AAV cap coding region" or “sequence encoding one or more cap proteins,” or “Cap encoding sequence” and grammatical equivalents thereof it is meant the art-recognized region of the AAV genome which encodes the coat proteins of the virus which are required for the capsid that viral genome or a payload is packaged into by the Rep proteins. For a further description of the cap coding region, see, e.g., Muzyczka, N. (1992) Current Topics in Microbiol. and Immunol.158, 97-129; Kotin, R. M. (1994) Human Gene Therapy 5, 793-801. The AAV cap coding region, as used herein, may be derived from any AAV serotype, as described above. The region need not include all of the wild-type cap genes but may be altered, e.g., by the insertion, deletion or substitution of nucleotides, so long as the genes provide for sufficient packaging functions. Cap coding sequences are further described below. The term “AAV Cap coding sequence” and “AAV Cap proteins coding sequence” are interchangeably used herein. The terms “AAV Cap proteins”, “Cap proteins”, “AAV Cap polypeptide”, and “Cap polypeptide” are interchangeably used herein. The term “Capsid” and “Cap” are interchangeably used herein. [0106] By "adeno-associated virus inverted terminal repeats" or "AAV ITRs" is meant the art-recognized regions found at each end of the AAV genome which function together in cis as origins of DNA replication and as packaging signals for the viral genome. The nucleotide sequences of AAV ITR regions are known. See, e.g., Kotin, R. M. (1994) Human Gene Therapy 5, 793-801; Berns, K. I. "Parvoviridae and their Replication" in Fundamental Virology, 2d ed., (B. N. Fields and D. M. Knipe, eds.) for the AAV-2 ITRs sequence. As used herein, an "AAV ITR" need not have a wild-type nucleotide sequence, but may be altered, e.g., by the insertion, deletion or substitution of nucleotides. The AAV ITR may be derived from any of several AAV serotypes, including without limitation, AAV-1, AAV-2, AAV-3, AAV-4, AAV-5, AAV-7, etc. Furthermore, 5' and 3' ITRs which flank a selected nucleotide sequence in an AAV vector need not necessarily be identical or derived from the same AAV serotype or isolate. The ITRs may be single stranded (ssITRs) or self-complementary (scITRs). [0107] A "helper virus" for AAV refers to a virus that allows AAV (e.g., wild-type AAV) to be replicated and packaged by a mammalian cell. A variety of such helper viruses for AAV are known in the art, including adenoviruses, herpesviruses and poxviruses such as vaccinia. The adenoviruses encompass a number of different subgroups, although Adenovirus type 5 of subgroup C is most commonly used. Numerous adenoviruses of human, non-human mammalian and avian origin are known and available from depositories such as the ATCC. Viruses of the herpes family include, for example, herpes simplex viruses (HSV) and Epstein-Barr viruses (EBV), as well as cytomegaloviruses (CMV) and pseudorabies viruses (PRV); which are also available from depositories such as ATCC. [0108] The term “adenoviral helper proteins” and “AAV helper proteins” are interchangeably used herein. [0109] "Helper virus function(s)" refers to function(s) encoded in a helper virus genome which allows AAV replication and packaging (in conjunction with other requirements for replication and packaging described herein). As described herein, "helper virus function" may be provided in a number of ways, including by providing helper virus or providing, for example, polynucleotide sequences encoding the requisite function(s) to a producer cell in trans. [0110] An "infectious" virus or viral particle is one that comprises a polynucleotide component which the particle is capable of delivering into a cell for which the viral species is tropic. The term does not necessarily imply any replication capacity of the virus. As used herein, an “infectious” virus or viral particle is one that may access a target cell, may infect a target cell, and may express a heterologous nucleic acid in a target cell. Thus, “infectivity” refers to the ability of a viral particle to access a target cell, infect a target cell, and express a heterologous nucleic acid in a target cell. Infectivity may refer to in vitro infectivity or in vivo infectivity. Assays for counting infectious viral particles are described elsewhere in this disclosure and in the art. Viral infectivity may be expressed as the ratio of infectious viral particles to total viral particles. Total viral particles may be expressed as the number of viral genome (vg) copies. The ability of a viral particle to express a heterologous nucleic acid in a cell may be referred to as “transduction.” The ability of a viral particle to express a heterologous nucleic acid in a cell may be assayed using a number of techniques, including assessment of a marker gene, such as a green fluorescent protein (GFP) assay (e.g., where the virus comprises a nucleotide sequence encoding GFP), where GFP is produced in a cell infected with the viral particle and is detected and/or measured; or the measurement of a produced protein, for example by an enzyme-linked immunosorbent assay (ELISA). Viral infectivity may be expressed as the ratio of infectious viral particles to total viral particles. Methods of determining the ratio of infectious viral particle to total viral particle are known in the art. See, e.g., Grainger et al. (2005) Mol. Ther.11:S337 (describing a TCID50 infectious titer assay); and Zolotukhin et al. (1999) Gene Ther.6:973. [0111] The term "polynucleotide" refers to a polymeric form of nucleotides of any length, including deoxyribonucleotides or ribonucleotides, or analogs thereof. The terms “polynucleotide” and “nucleic acid” are interchangeably used herein. A polynucleotide may comprise modified nucleotides, such as methylated nucleotides and nucleotide analogs, and may be interrupted by non-nucleotide components. If present, modifications to the nucleotide structure may be imparted before or after assembly of the polymer. The term polynucleotide, as used herein, refers interchangeably to double- and single-stranded molecules. Unless otherwise specified or required, any embodiment of the invention described herein that is a polynucleotide encompasses both the double-stranded form and each of two complementary single-stranded forms known or predicted to make up the double-stranded form. [0112] As used herein, the term “polynucleotide construct” refers to a DNA segment of any size that includes one or more sequences encoding an RNA or protein and at least one promoter for driving expression from the one or more sequences. The term “polynucleotide construct” and “nucleic acid construct” are interchangeably used herein. A polynucleotide construct may be a circular DNA or a linear DNA. A polynucleotide construct may be single stranded or double stranded. As used herein, the term "vector" includes any genetic element, such as a plasmid, phage, transposon, cosmid, chromosome, artificial chromosome, virus, virion, etc., which is capable of replication when associated with the proper control elements and which may transfer gene sequences into and between cells. Thus, the term includes cloning and expression vehicles, as well as viral vectors. The use of the term "vector" throughout this specification encompasses plasmid or viral vectors, which permit the desired components to be transferred to the host cell via transfection or infection. For example, an adeno-associated viral (AAV) vector is a plasmid comprising a recombinant AAV genome. In some embodiments, useful vectors are contemplated to be those vectors in which the nucleic acid segment to be transcribed is positioned under the transcriptional control of a promoter. A vector may be linear or circular, single stranded or double stranded, DNA or RNA. In certain aspects, the vector may be circular, double stranded DNA. [0113] As used herein, the term “vector system” refers to two or more vectors that are used together, e.g., by simultaneous or sequential introduction into a cell, to provide at least two different components into the cell. The two different components may then work together in the cell. [0114] A polynucleotide or polypeptide has a certain percent "sequence identity" to another polynucleotide or polypeptide, meaning that, when aligned, that percentage of bases or amino acids are the same when comparing the two sequences. The term percent “sequence identity,” in the context of two or more nucleic acid or polypeptide sequences, refers to two or more sequences or subsequences that have a specified percentage of nucleotides or amino acid residues that are the same, when compared and aligned for maximum correspondence, as measured using one of the sequence comparison algorithms described below (e.g., BLASTP and BLASTN or other algorithms available to persons of skill) or by visual inspection. Depending on the application, the percent “sequence identity” can exist over a region of the sequence being compared, e.g., over a functional domain, or, alternatively, exist over the full length of the two sequences to be compared. [0115] For sequence comparison, typically one sequence acts as a reference sequence (also called the subject sequence) to which test sequences (also called query sequences) are compared. The percent sequence identity is defined as a test sequence’s percent identity to a reference sequence. For example, when stated “Sequence A having a sequence identity of 50% to Sequence B,” Sequence A is the test sequence and Sequence B is the reference sequence. When using a sequence comparison algorithm, test and reference sequences are input into a computer program, subsequence coordinates are designated, if necessary, and sequence algorithm program parameters are designated. The sequence comparison algorithm then aligns the sequences to achieve the maximum alignment, based on the designated program parameters, introducing gaps in the alignment if necessary. The percent sequence identity for the test sequence(s) relative to the reference sequence can then be determined from the alignment of the test sequence to the reference sequence. The equation for percent sequence identity from the aligned sequence is as follows: [0116] [(Number of Identical Positions)/(Total Number of Positions in the Test Sequence)] × 100% [0117] For purposes herein, percent identity and sequence similarity calculations are performed using the BLAST algorithm for sequence alignment, which is described in Altschul et al., J. Mol. Biol.215:403-410 (1990). Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information (www.ncbi.nlm.nih.gov/). The BLAST algorithm uses a test sequence (also called a query sequence) and a reference sequence (also called a subject sequence) to search against, or in some cases, a database of multiple reference sequences to search against. The BLAST algorithm performs sequence alignment by finding high-scoring alignment regions between the test and the reference sequences by scoring alignment of short regions of the test sequence (termed “words”) to the reference sequence. The scoring of each alignment is determined by the BLAST algorithm and takes factors into account, such as the number of aligned positions, as well as whether introduction of gaps between the test and the reference sequences would improve the alignment. The alignment scores for nucleic acids can be scored by set match/mismatch scores. For protein sequences, the alignment scores can be scored using a substitution matrix to evaluate the significance of the sequence alignment, for example, the similarity between aligned amino acids based on their evolutionary probability of substitution. For purposes herein, the substitution matrix used is the BLOSUM62 matrix. For purposes herein, the public default values of April 6, 2023 are used when using the BLASTN and BLASTP algorithms. The BLASTN and BLASTP algorithms then output a “Percent Identity” output value and a “Query Coverage” output value. The overall percent sequence identity as used herein can then be calculated from the BLASTN or BLASTP output values as follows: [0118] Percent Sequence Identity = (“Percent Identity” output value) × (“Query Coverage” output value) [0119] The following non-limiting examples illustrate the calculation of percent identity between two nucleic acids sequences. The percent identity is calculated as follows: [(number of identical nucleotide positions)/(total number of nucleotides in the test sequence)] × 100%. Percent identity is calculated to compare test sequence 1: AAAAAGGGGG (length = 10 nucleotides) to reference sequence 2: AAAAAAAAAA (length = 10 nucleotides). The percent identity between test sequence 1 and reference sequence 2 would be [(5)/(10)] ×100% = 50%. Test sequence 1 has 50% sequence identity to reference sequence 2. In another example, percent identity is calculated to compare test sequence 3: CCCCCGGGGGGGGGGCCCCC (length = 20 nucleotides) to reference sequence 4: GGGGGGGGGG (length = 10 nucleotides). The percent identity between test sequence 3 and reference sequence 4 would be [(10)/(20)] ×100% = 50%. Test sequence 3 has 50% sequence identity to reference sequence 4. In another example, percent identity is calculated to compare test sequence 5: GGGGGGGGGG (length = 10 nucleotides) to reference sequence 6: CCCCCGGGGGGGGGGCCCCC (length = 20 nucleotides). The percent identity between test sequence 5 and reference sequence 6 would be [(10)/(10)] ×100% = 100%. Test sequence 5 has 100% sequence identity to reference sequence 6. [0120] The following non-limiting examples illustrate the calculation of percent identity between two protein sequences. The percent identity is calculated as follows: [(number of identical amino acid positions)/(total number of amino acids in the test sequence)] × 100%. Percent identity is calculated to compare test sequence 7: FFFFFYYYYY (length = 10 amino acids) to reference sequence 8: YYYYYYYYYY (length = 10 amino acids). The percent identity between test sequence 7 and reference sequence 8 would be [(5)/(10)] ×100% = 50%. Test sequence 7 has 50% sequence identity to reference sequence 8. In another example, percent identity is calculated to compare test sequence 9: LLLLLFFFFFYYYYYLLLLL (length = 20 amino acids) to reference sequence 10: FFFFFYYYYY (length = 10 amino acids). The percent identity between test sequence 9 and reference sequence 10 would be [(10)/(20)] ×100% = 50%. Test sequence 9 has 50% sequence identity to reference sequence 10. In another example, percent identity is calculated to compare test sequence 11: FFFFFYYYYY (length = 10 amino acids) to reference sequence 12: LLLLLFFFFFYYYYYLLLLL (length = 20 amino acids). The percent identity between test sequence 11 and reference sequence 12 would be [(10)/(10)] ×100% = 100%. Test sequence 11 has 100% sequence identity to reference sequence 12. [0121] For purposes herein, reference to a polynucleotide sequence (e.g., a DNA sequence or an RNA sequence) also encompasses the reverse complement of the polynucleotide sequence. For example, a sequence of AAAAAGGGGG also encompasses a sequence of CCCCCTTTTT. [0122] A "gene" refers to a polynucleotide containing at least one open reading frame that is capable of encoding a particular protein after being transcribed and translated. [0123] The term "host cell" denotes, for example, microorganisms, yeast cells, insect cells, and mammalian cells, that may be, or have been, used as recipients of an AAV vector system as described herein, or other transfer DNA. The term includes the progeny of the original cell which has been transfected. Thus, a "host cell" as used herein generally refers to a cell which has been transfected with an exogenous DNA sequence. It is understood that the progeny of a single parental cell may not necessarily be completely identical in morphology or in genomic or total DNA complement to the original parent, due to natural, accidental, or deliberate mutation. In some aspects, the disclosure provides transfected host cells. [0124] The term "transfection" is used to refer to the uptake of foreign DNA by a cell, and a cell has been "transfected" when exogenous DNA has been introduced inside the cell membrane. A number of transfection techniques are generally known in the art. See, e.g., Graham et al. (1973) Virology, 52:456, Sambrook et al. (1989) Molecular Cloning, a laboratory manual, Cold Spring Harbor Laboratories, New York, Davis et al. (1986) Basic Methods in Molecular Biology, Elsevier, and Chu et al. (1981) Gene 13:197. Such techniques can be used to introduce one or more exogenous nucleic acids, such as a nucleotide integration vector and other nucleic acid molecules, into suitable host cells. [0125] As used herein, the term "cell line" refers to a population of cells capable of continuous or prolonged growth and division in vitro. Often, cell lines are clonal populations derived from a single progenitor cell. It is further known in the art that spontaneous or induced changes may occur in karyotype during storage or transfer of such clonal populations. Therefore, cells derived from the cell line referred to may not be precisely identical to the ancestral cells or cultures, and the cell line referred to includes such variants. [0126] The term "cell culture," refers to cells grown adherent or in suspension, bioreactors, roller bottles, hyperstacks, microspheres, macrospheres, flasks and the like, as well as the components of the supernatant or suspension itself, including but not limited to rAAV particles, cells, cell debris, cellular contaminants, colloidal particles, biomolecules, host cell proteins, nucleic acids, and lipids, and flocculants. Large scale approaches, such as bioreactors, including suspension cultures and adherent cells growing attached to microcarriers or macrocarriers in stirred bioreactors, are also encompassed by the term "cell culture." Cell culture procedures for both large and small-scale production of proteins are encompassed by the present disclosure. [0127] As used herein, the terms "recombinant cell" refers to a cell into which an exogenous DNA segment, such as DNA segment that leads to the transcription of a biologically-active polypeptide or production of a biologically active nucleic acid such as an RNA, has been introduced. [0128] As used herein, the term “intermediate cell line” refers to a cell line that contains the AAV rep and cap components integrated into the host cell genome or a cell line that contains the adenoviral helper functions integrated into the host cell genome. [0129] As used herein, the term “packaging cell line” refers to a cell line that contains the AAV rep and cap components and the adenoviral helper functions integrated into the host cell genome. A payload construct must be added to the packaging cell line to generate rAAV virions. [0130] As used herein, the term “production cell line” refers to a cell line that contains the AAV rep and cap components, the adenoviral helper functions, and a payload construct. The rep and cap components and the adenoviral helper functions are integrated into the host cell genome. The payload construct can be stably integrated into the host cell genome or transiently transfected. rAAV virions can be generated from the production cell line upon the introduction of one or more triggering agents in the absence of any plasmid or transfection agent. [0131] As used herein, the term “downstream purification” refers to the process of separating rAAV virions from cellular and other impurities. Downstream purification processes include chromatography-based purification processes, such as ion exchange (IEX) chromatography and affinity chromatography. [0132] The term “prepurification yield” refers to the rAAV yield prior to the downstream purification processes. The term “postpurification yield” refers to the rAAV yield after the downstream purification processes. rAAV yield can be measured as viral genome (vg)/L. [0133] The encapsidation ratio of a population of rAAV virions can be measured as the ratio of rAAV viral particle (VP) to viral genome (VG). The rAAV viral particle includes empty capsids, partially full capsids (e.g., comprising a partial viral genome), and full capsids (e.g., comprising a full viral genome). [0134] The F:E ratio of a population of rAAV virions can be measured as the ratio of rAAV full capsids to empty capsids. The rAAV full capsid particle includes partially full capsids (e.g., comprising a partial viral genome) and full capsids (e.g., comprising a full viral genome). The empty capsids lack a viral genome. [0135] The potency or infectivity of a population of rAAV virions can be measured as the percentage of target cells infected by the rAAV virions at a multiplicity of infection (MOI; viral genomes/target cell). Exemplary MOI values are 1 × 101, 1 × 102, 2 × 103, 5 × 104, or 1 × 105 vg/target cell. An MOI can be a value chosen from the range of 1 × 101 to 1 × 105 vg/target cell. [0136] The term "expression vector or construct" or “synthetic construct” means any type of genetic construct containing a nucleic acid in which part or all of the nucleic acid encoding sequence is capable of being transcribed. In some embodiments, expression includes transcription of the nucleic acid, for example, to generate a biologically-active polypeptide product or functional RNA (e.g., guide RNA) from a transcribed gene. [0137] The term “auxotrophic” or “auxotrophic selectable marker” as used herein refers to the usage of a medium lacking a supplement, such as a medium lacking an essential nutrient such as the purine precursors hypoxanthine and thymidine (HT), or the like, for selection of a functional enzyme which allows for growth in the medium lacking the essential nutrient, e.g., a functional dihydrofolate reductase or the like. [0138] The terms “tetracycline” is used generically herein to refer to all antibiotics that are structurally and functionally related to tetracycline, including tetracycline, doxycycline, demeclocycline, minocycline, sarecycline, oxytetracycline, omadacycline, or eravacycline. [0139] The terms “constitutive” or “constitutive expression” are used interchangeably herein. They refer to genes that are transcribed in an ongoing manner. Such gene are driven by a constitutive promoter. In some embodiments, the terms refer to the expression of a therapeutic payload or a nucleic acid sequence that is not conditioned on addition of an triggering agent to the cell culture medium. A constitutive promoter is capable of directing continuous gene expression in a cell. Constitutive promoters regulate expression of basal genes, like housekeeping genes. In contrast, an inducible promoter directs gene expression in the presence of an external stimulus. Thus, an inducible promoter can be controlled by providing or withdrawing the stimulus. [0140] As used herein, the term “polynucleotide payload” refers to a polynucleotide sequence that is packaged into a rAAV virion for delivery by the rAAV virion into a cell. A polynucleotide payload is flanked by AAV inverted terminal repeats (ITRs). Upon delivery to a cell, the polynucleotide payload may be available to the cell as a DNA (e.g., a homology region for homology-directed repair), transcribed into an RNA (e.g., a guide RNA (gRNA), a tRNA, a suppressor tRNA, a siRNA, a miRNA, an mRNA, a shRNA, a circular RNA, an antisense oligonucleotide (ASO)), or transcribed and translated into a polypeptide (e.g., an antibody, a hormone, a site-specific endonuclease, a reporter gene, a component of a CRISPR/Cas system, an adenosine deaminase acting on RNA (ADAR) enzyme, a transcriptional activator, a transcriptional repressor, a ribozyme, or a DNAzyme. [0141] "Recombinant," as applied to a polynucleotide means that the polynucleotide is the product of various combinations of cloning, restriction or ligation steps, and other procedures that result in a construct that is distinct from a polynucleotide found in nature. A recombinant virus is a viral particle comprising a recombinant polynucleotide. The terms respectively include replicates of the original polynucleotide construct and progeny of the original virus construct. [0142] A "control element" or "control sequence" is a nucleotide sequence involved in an interaction of molecules that contributes to the functional regulation of a polynucleotide, including replication, duplication, transcription, splicing, translation, or degradation of the polynucleotide. The regulation may affect the frequency, speed, or specificity of the process, and may be enhancing or inhibitory in nature. Control elements known in the art include, for example, transcriptional regulatory sequences such as promoters and enhancers. A promoter is a DNA region capable under certain conditions of binding RNA polymerase and initiating transcription of a coding region usually located downstream (in the 3' direction) from the promoter. A promoter is usually upstream of a gene whose expression is controlled by the promoter. [0143] "Operatively linked" or "operably linked" refers to a juxtaposition of genetic elements, wherein the elements are in a relationship permitting them to operate in the expected manner. For instance, a promoter is operatively linked to a coding region if the promoter helps initiate transcription of the coding sequence. There may be intervening residues between the promoter and coding region so long as this functional relationship is maintained. [0144] "Heterologous" means derived from a genotypically distinct entity from that of the rest of the entity to which it is being compared. For example, a polynucleotide introduced by genetic engineering techniques into a plasmid or vector derived from a different species is a heterologous polynucleotide. Additional sequences or sequence motifs operably linked to a sequence where it is not naturally found are also heterologous; such sequences or sequence motifs include polyA signal sequences, introns, and/or any other relevant sequence. Thus, for example, an rAAV that includes a heterologous nucleic acid encoding a heterologous payload is an rAAV that includes a nucleic acid not normally included in a naturally occurring, wild-type AAV, and the encoded heterologous payload is a payload not normally encoded by a naturally- occurring, wild-type AAV. As another example, a Capsid proteins coding sequence operably linked to a heterologous polyA signal sequence refers to a AAV Cap coding sequence operably linked to a sequence not native to AAV. [0145] A cell is said to be "stably" altered, transduced, genetically modified, or transformed with a genetic sequence if the sequence is available to perform its function during extended culture of the cell in vitro. Generally, such a cell is "heritably" altered (genetically modified) in that a genetic alteration is introduced which is also inheritable by progeny of the altered cell. For example, a gene integrated into the nuclear genome of the cell and is available to perform its function during extended culture of the cell in vitro. A gene integrated into the nuclear genome of the cell is inheritable by progeny of the cell. [0146] A cell is said to be "stably" altered, transduced, genetically modified, or transformed with a genetic sequence if the sequence is available to perform its function during extended culture of the cell in vitro. Generally, such a cell is "heritably" altered (genetically modified) in that a genetic alteration is introduced which is also inheritable by progeny of the altered cell. For example, a gene integrated into the nuclear genome of the cell and is available to perform its function during extended culture of the cell in vitro. A gene integrated into the nuclear genome of the cell is inheritable by progeny of the cell. [0147] The terms "polypeptide," "peptide," and "protein" are used interchangeably herein to refer to polymers of amino acids of any length. The terms also encompass an amino acid polymer that has been modified; for example, disulfide bond formation, glycosylation, lipidation, phosphorylation, or conjugation with a labeling component. Polypeptides such as anti-angiogenic polypeptides, neuroprotective polypeptides, and the like, when discussed in the context of delivering a payload to a mammalian subject, and compositions therefor, refer to the respective intact polypeptide, or any fragment or genetically engineered derivative thereof, which retains the desired biochemical function of the intact protein. Similarly, references to nucleic acids encoding anti-angiogenic polypeptides, nucleic acids encoding neuroprotective polypeptides, and other such nucleic acids for use in delivery of a payload to a mammalian subject (which may be referred to as "transgenes" to be delivered to a recipient cell), include polynucleotides encoding the intact polypeptide or any fragment or genetically engineered derivative possessing the desired biochemical function. [0148] An "isolated" plasmid, nucleic acid, vector, virus, virion, host cell, or other substance refers to a preparation of the substance devoid of at least some of the other components that may also be present where the substance or a similar substance naturally occurs or is initially prepared from. Thus, for example, an isolated substance may be prepared by using a purification technique to enrich it from a source mixture. Enrichment may be measured on an absolute basis, such as weight per volume of solution, or it may be measured in relation to a second, potentially interfering substance present in the source mixture. Increasing enrichments of the embodiments of this invention are increasingly more isolated. An isolated plasmid, nucleic acid, vector, virus, host cell, or other substance is in some cases purified, e.g., from about 80% to about 90% pure, at least about 90% pure, at least about 95% pure, at least about 98% pure, or at least about 99%, or more, pure. [0149] The terms "treatment", "treating", "treat" and the like are used herein to generally refer to obtaining a desired pharmacologic and/or physiologic effect. The effect may be prophylactic in terms of completely or partially preventing a disease or symptom(s) thereof and/or may be therapeutic in terms of a partial or complete stabilization or cure for a disease and/or adverse effect attributable to the disease. The term “treatment" encompasses any treatment of a disease in a mammal, particularly a human, and includes: (a) preventing the disease and/or symptom(s) from occurring in a subject who may be predisposed to the disease or symptom(s) but has not yet been diagnosed as having it; (b) inhibiting the disease and/or symptom(s), i.e., arresting development of a disease and/or the associated symptoms; or (c) relieving the disease and the associated symptom(s), i.e., causing regression of the disease and/or symptom(s). Those in need of treatment may include those already afflicted (e.g., those with a neurological disorder) as well as those in which prevention is desired (e.g., those with increased susceptibility to a neurological disorder; those suspected of having a neurological disorder; those having one or more risk factors for a neurological disorder, etc.). [0150] A "therapeutically effective amount" or "efficacious amount" means the amount of a compound that, when administered to a mammal or other subject for treating a disease, is sufficient, in combination with another agent, or alone in one or more doses, to effect such treatment for the disease. The "therapeutically effective amount" will vary depending on the compound, the disease and its severity and the age, weight, etc., of the subject to be treated. [0151] The terms “individual,” “host,” “subject,” and “patient” are used interchangeably herein, and refer to a mammal, including, but not limited to, human and non-human primates, including simians and humans; mammalian sport animals (e.g., horses, camels, etc.); mammalian farm animals (e.g., sheep, goats, cows, etc.); mammalian pets (dogs, cats, etc.); and rodents (e.g., mice, rats, etc.). In some cases, the individual is a human. [0152] The terms “v1.1 system” and “v1.2” system are interchangeable and are used herein to refer to the same version of system of polynucleotides. [0153] The terms "hybridize" and "hybridization" refer to the formation of complexes between nucleotide sequences which are sufficiently complementary to form complexes via Watson Crick base pairing. [0154] The term "homologous region" refers to a region of a nucleic acid with homology to another nucleic acid region. Thus, whether a "homologous region" is present in a nucleic acid molecule is determined with reference to another nucleic acid region in the same or a different molecule. Further, since a nucleic acid is often double-stranded, the term "homologous, region," as used herein, refers to the ability of nucleic acid molecules to hybridize to each other. For example, a single-stranded nucleic acid molecule may have two homologous regions which are capable of hybridizing to each other. Thus, the term "homologous region" includes nucleic acid segments with complementary sequences. Homologous regions may vary in length but will typically be between 4 and 500 nucleotides (e.g., from about 4 to about 40, from about 40 to about 80, from about 80 to about 120, from about 120 to about 160, from about 160 to about 200, from about 200 to about 240, from about 240 to about 280, from about 280 to about 320, from about 320 to about 360, from about 360 to about 400, from about 400 to about 440, etc.). [0155] As used herein, the terms "complementary" or "complementarity" refers to polynucleotides that are able to form base pairs with one another. Base pairs are typically formed by hydrogen bonds between nucleotide units in an anti-parallel orientation between polynucleotide strands. Complementary polynucleotide strands may base pair in a Watson-Crick manner (e.g., A to T, A to U, C to G), or in any other manner that allows for the formation of duplexes. As persons skilled in the art are aware, when using RNA as opposed to DNA, uracil (U) rather than thymine (T) is the base that is considered to be complementary to adenosine. However, when a uracil is denoted in the context of the present invention, the ability to substitute a thymine is implied, unless otherwise stated. "Complementarity" may exist between two RNA strands, two DNA strands, or between an RNA strand and a DNA strand. It is generally understood that two or more polynucleotides may be "complementary" and able to form a duplex despite having less than perfect or less than 100% complementarity. Two sequences are "perfectly complementary" or "100% complementary" if at least a contiguous portion of each polynucleotide sequence, comprising a region of complementarity, perfectly base pairs with the other polynucleotide without any mismatches or interruptions within such region. Two or more sequences are considered "perfectly complementary" or "100% complementary" even if either or both polynucleotides contain additional non-complementary sequences as long as the contiguous region of complementarity within each polynucleotide is able to perfectly hybridize with the other. "Less than perfect" complementarity refers to situations where less than all of the contiguous nucleotides within such region of complementarity are able to base pair with each other. Determining the percentage of complementarity between two polynucleotide sequences is a matter of ordinary skill in the art. As used herein, the term "recombination site" denotes a region of a nucleic acid molecule comprising a binding site or sequence-specific motif recognized by a site-specific recombinase that binds at the target site and catalyzes recombination of specific sequences of DNA at the target site. Site-specific recombinases catalyze recombination between two such target sites. The relative orientation of the target sites determines the outcome of recombination. For example, translocation occurs if the recombination sites are on separate DNA molecules. DNA between two recombination sites oriented in the same direction on the same DNA molecule will be excised as a circular loop of DNA. DNA between two recombination sites that are orientated in the opposite direction on the same DNA molecule will be inverted. [0156] The terms "v1.1 system" and "v1.2 system” are interchangeable and are used herein to refer to the same version of system of polynucleotides. 1.2. Overview [0157] To solve the problems associated with low rAAV titers, disclosed herein are polynucleotide constructs and cells, such as, cell lines stably integrated with the polynucleotide constructs that enable increased production of recombinant AAV (rAAV) virions. FIG.10 shows that in a v1.0 system, the production of payload sequences is higher than capsid production, indicating that capsid production could be a rate limiting step for producing encapsidated payloads, i.e., rAAV. FIG.10 demonstrates that increased encaspidated payload titer, i.e., increased rAAV titer was acheived by increasing total capsid production. Thus, increased production of rAAV is achieved by providing an overall increase in the levels of capsid proteins which in turn increases production of rAAV. Disclosed herein are various methods and constructs for increasing capsid production and therefore also increasing the titer of encapsidated genomes. In one embodiment, the increase in levels of capsid proteins is achieved by including a strong polyadenylation (polyA) signal sequence 3' to the sequence encoding the capsid proteins. In another embodiment, the increase in levels of capsid proteins is achieved by using an inducible promoter to drive expression of capsid proteins. In a further embodiment, the increase in levels of AAV capsid proteins is achieved by including a strong polyadenylation (polyA) signal sequence 3’ to the sequence encoding the AAV capsid proteins and by using an inducible promoter to drive expression of capsid proteins which inducible promoter is stronger than the native promoter controlling expression of AAV capsid proteins. In another embodiment, the increase in levels of capsid proteins is achieved by using two separate polynucleotide constructs each encoding AAV capsid proteins, one under the control of a native promoter and another under the control of an inducible promoter. One or more of these embodiments can also be combined to increase capsid proteins expression and enable increased production of recombinant AAV (rAAV). These embodiments are further described in detail below. 1.3. Polynucleotides Encoding AAV Capsid Proteins AAV Cap Encoding Sequence linked to PolyA Signal Sequence [0158] In some aspects, polynucleotides comprising (i) a sequence encoding AAV Cap proteins and (ii) a polyadenylation signal sequence. In some embodiments, the polyadenylation signal sequence encodes a stronger polyadenylation signal than a native AAV Cap polyadenylation signal sequence. In some embodiments, the polyadenylation signal sequence is 3' of the sequence encoding AAV Cap proteins are provided. In certain embodiments, the polynucleotides comprise (i) a sequence encoding AAV Cap proteins and (ii) a polyadenylation signal sequence, wherein the polyadenylation signal sequence encodes a stronger polyadenylation signal than a native AAV Cap polyadenylation signal sequence and is a 3' of the sequence encoding AAV Cap proteins. Suitable polyadenylation signals are further described below in the section “Polyadenylation Signals”. Polyadenylation Signals [0159] Polyadenylation (polyA) signal sequences generally include a short sequence that triggers polyadenylation of an mRNA. In certain instances, RNA stability, expression, and/or function can be enhanced with additional sequences surrounding a shorter sequence. Various polyA signaling sequences can be used for the coding sequences of various embodiments. [0160] In some embodiments, the polyadenylation signal sequence is a SV40 polyadenylation signal sequence (SV40 polyA). In other embodiments, the polyadenylation signal sequence is a bovine growth hormone polyadenylation signal sequence (bGH polyA). In still other embodiments, the polyadenylation signal sequence is a Rabbit Beta Globin polyadenylation signal sequence. [0161] In some embodiments, the polyadenylation signal sequence has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to SEQ ID NO: 152 (SV40 poly A). In certain embodiments, the polyadenylation signal sequence has sequence of SEQ ID NO: 152 (SV40 poly A). In certain embodiments, the polyadenylation signal sequence has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to SEQ ID NO: 151 (bGH polyA). In certain embodiments, the polyadenylation signal sequence has sequence of SEQ ID NO: 151 (bGH polyA). In some embodiments, the polyadenylation signal sequence has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to SEQ ID NO: 170 (Rabbit Beta Globin PolyA). In certain embodiments, the polyadenylation signal sequence has sequence of SEQ ID NO: 170 (Rabbit Beta Globin PolyA). [0162] In some embodiments, the polyadenylation signal sequence is any polyadenylation signal sequence that encodes a stronger polyadenylation signal than a native AAV Cap polyadenylation signal sequence. In some embodiments, the native AAV Cap polyadenylation signal sequence has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to SEQ ID NO: 162. In certain embodiments, the native AAV Cap polyadenylation signal sequence has sequence of SEQ ID NO: 162. [0163] In some embodiments, the stronger polyadenylation signal enhances RNA processing, RNA stability, RNA translation efficiency, or any combination thereof. [0164] In some embodiments, the polynucleotide described herein is not flanked by inverted terminal repeat sequences.

AAV Cap proteins [0166] In some embodiments, the AAV Cap proteins comprise VP1, VP2, and VP3. [0167] In some embodiments, a serotype of the AAV Cap proteins is selected from the group consisting of AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAV 10, AAV11, AAV 12, AAV13, AAV 14, AAV 15 and AAV 16, AAV.rh8, AAV.rh10, AAV.rh20, AAV.rh39, AAV.Rh74, AAV.RHM4-1, AAV.hu37, AAV.Anc80, AAV.Anc80L65, AAV.7m8, AAV.PHP.B, AAV2.5, AAV2tYF, AAV3B, AAV.LK03, AAV.HSC1, AAV.HSC2, AAV.HSC3, AAV.HSC4, AAV.HSC5, AAV.HSC6, AAV.HSC7, AAV.HSC8, AAV.HSC9, AAV.HSC10, AAV.HSC11, AAV.HSC12, AAV.HSC13, AAV.HSC14, AAV.HSC15, AAV.HSC16 and AAVhu68. In some embodiments, the serotype is an AAV5 Cap protein which comprises one or more mutations or insertions. In some embodiments, the AAV Cap proteins encode for AAV5 Cap proteins. In some embodiments, the AAV Cap proteins encode for AAV9 Cap proteins. In some embodiments, the serotype is an AAV9 Cap protein which comprises one or more mutations or insertions. In some embodiments, the AAV Cap proteins encode for PhP.EB Cap proteins. In some embodiments, the serotype is an PhP.EB Cap protein which comprises one or more mutations or insertions. In some embodiments, the AAV Cap proteins encode for AAV8 Cap proteins. In some embodiments, the serotype is an AAV8 Cap protein which comprises one or more mutations or insertions.

In some embodiments, the AAV Cap proteins encode for AAV6 Cap proteins. In some embodiments, the serotype is an AAV6 Cap protein which comprises one or more mutations or insertions. AAV Cap Encoding Sequence linked to Inducible Promoter [0168] In some aspects, polynucleotides comprising (i) a sequence encoding AAV Cap proteins operably linked to an inducible promoter and (ii) a polyadenylation signal sequence, wherein the polyadenylation signal sequence encodes a stronger polyadenylation signal than a native AAV Cap polyadenylation signal sequence and is 3' of the sequence encoding AAV Cap proteins are provided. Any suitable inducible promoter that is stronger than the native p40 promoter may be used for increasing AAV Cap proteins expression. Suitable inducible promoters are further described below in the section "Inducible Promoters". Inducible Promoters [0169] In certain aspects, the inducible promoters are selected on the basis of the regulatory sequence that allows for control of the promoter. The regulatory sequence may be operably linked to the promoter and positioned upstream of the promoter. Such regulatory sequences are known to those of skill in the art, and examples include those which cause the expression of a gene to be turned on or off in response to a chemical or physical stimulus, including the presence of a regulatory compound. The regulatory sequence used to control expression may be endogenous or exogenous to the host cell. In some embodiments, bacterial gene control elements in combination with viral transactivator proteins are used to provide mammalian inducible expression. Examples of mammalian-compatible regulatory sequences include those capable of controlling an engineered promoter to adjust transcription in response to antibiotics including, without limitation, tetracyclines, streptogramins, and macrolides. For example, inclusion of a bacterial tetracycline response element (TRE) in a construct allows mammalian expression to be induced by tetracycline or a derivative thereof (e.g., doxycycline).

[0170] In some embodiments, the inducible promoter is a tetracycline-inducible promoter. In other embodiments, the inducible promoter is an ecdysone-inducible promoter. In still other embodiments, the inducible promoter is a cumate-inducible promoter. [0171] In some embodiments, the inducible promoter comprises a tetracycline-responsive promoter element (TRE). In certain embodiments, the TRE comprises Tet operator (tetO) sequence concatemers fused to a minimal promoter. In some embodiments, the minimal promoter is a human cytomegalovirus promoter. In some embodiments, the TRE comprises seven repeats of a 19 base pair operator sequence (tetO).

Payloads [0287] Disclosed herein are payloads that may be encoded for by polynucleotide construct 4, which encodes for a payload. This fourth polynucleotide is referred to herein as a “payload construct” or “therapeutic payload.” Thus, disclosed herein are stable mammalian cell lines that encapsidate a payload. In some embodiments, the payload may be an expressible payload. In some embodiments, the polynucleotide may encode for any therapeutic. For example, the therapeutic may be a transgene, a guide RNA, an antisense RNA, an oligonucleotide, an mRNA, a miRNA, a shRNA, a tRNA suppressor, a CRISPR-Cas protein, any gene editing enzyme, or any combination thereof. In some embodiments, the payload is guide RNA, wherein the guide RNA, when bound to a target RNA, recruits an ADAR enzyme for editing of the target RNA. In some embodiments, the payload is progranulin. In some embodiments, the stable mammalian cell lines disclosed herein can conditionally produce rAAV virions that encapsidate more than one payload. Any combination of payloads disclosed herein is contemplated. [0288] The sequence encoding a payload as disclosed herein encompasses any nucleotide sequence that is to be delivered to a cell. The nucleotide sequence may be utilized in the cell for, e.g., insertion of the nucleotide sequence or a part thereof. For example, the nucleotide sequence may be used to repair an endogenous DNA. In such a case, the nucleotide sequence itself is the payload being delivered by the rAAV to a cell. [0289] In other cases, the polynucleotide payload is transcribed in the cell into an RNA which is not translated into a protein. In such a case, the RNA is the payload that is delivered by the polynucleotide payload present in the rAAV. In other cases, the polynucleotide payload is transcribed in the cell into an mRNA which is translated into a protein. In such a case, the protein is the payload that is delivered by the polynucleotide payload present in the rAAV. [0290] The polynucleotide payload may include a promoter operably linked to a DNA sequence. The promoter may be any promoter that allows for transcription of the DNA in the cell. A payload disclosed herein may be a therapeutic payload. [0291] The DNA sequence may be transcribed to produce RNA in the cell. The RNA may be mRNA. The RNA may be a guide RNA (gRNA), a tRNA, a suppressor tRNA, an mRNA, or a circular RNA. The RNA may be a regulatory RNA of interest such as, but not limited to, a microRNA (miRNA), a small interfering RNA (siRNA), a short hairpin RNA (shRNA), a small nuclear RNA (snRNA), a long non-coding RNA (lncRNA), an antisense nucleic acid, and the like. [0292] The polynucleotide payload may be a gene encoding a polypeptide, such as, an antibody, a hormone, a site-specific endonuclease, a reporter gene, a component of a CRISPR/Cas system, an adenosine deaminase acting on RNA (ADAR) enzyme, a transcriptional activator, a transcriptional repressor, a ribozyme, a DNAzyme, or any combination thereof. [0293] A payload may include any one or combination of the following: a transgene, a tRNA suppressor, a guide RNA, or any other target binding/modifying oligonucleotide or derivative thereof, or payloads may include immunogens for vaccines, and elements for any gene editing machinery (DNA or RNA editing). Payloads may also include those that deliver a transgene encoding antibody chains or fragments that are amenable to viral vector-mediated expression (also referred to as “vectored or vectorized antibody” for gene delivery). See, e.g., Curr Opinion HIV AIDS.2015 May; 10(3): 190–197, describing vectored antibody gene delivery for the prevention or treatment of HIV infection. See also, U.S. Pat. No.10,780,182, which describes AAV delivery of trastuzumab (Herceptin) for treatment of HER2+ brain metastases. A payload disclosed herein may not be a therapeutic payload (e.g., a coding for a detectable marker such as GFP). In particular, in some instances the polynucleotide payload refers to a polynucleotide that may be a homology element for homology-directed repair, or polynucleotide transcribed into a guide RNA to be delivered for a variety of purposes. In some embodiments, the transgene refers to a nucleic acid sequence coding for expression of guide RNA for ADAR editing or ADAT editing. In some embodiments, the transgene refers to a transgene packaged for gene therapy. In some embodiments, the transgene refers to synthetic constructs packaged for vaccines. In certain aspects, a polynucleotide payload may be described as encoding an RNA, which is meant to refer to the RNA transcribed from the polynucleotide. [0294] In certain examples, the sequence encoding the payload comprises two expressible sequences, wherein a first expressible sequence encodes for a first gRNA and a second expressible sequence encodes for a second gRNA. In some embodiments, the first gRNA and the second gRNA are different. In some embodiments, the first gRNA and the second gRNA are the same. In certain examples, the sequence encoding the payload comprises two or more expressible sequences. In some embodiments, the two or more expressible sequences encode for two or more gRNA. In some embodiments, the two or more gRNA are all different gRNA, all the same gRNA, or a combination of the same and different gRNA. [0295] In some cases, the sequence encoding the payload comprises an expressible sequence encoding both a heterologous RNA and a heterologous polypeptide. In other cases, the expressible sequence encodes two or more heterologous payloads. Where the expressible sequence encodes two heterologous payloads, in some cases, the nucleotide sequences encoding the two heterologous payloads are operably linked to the same promoter. Where the expressible sequence encodes two heterologous payloads, in some cases, the nucleotide sequences encoding the two heterologous payloads are operably linked to two different promoters. In some cases, sequence encoding the payload comprises an expressible sequence encoding three heterologous payloads. Where the expressible sequence encodes three heterologous payloads, in some cases, the nucleotide sequences encoding the three heterologous payloads are operably linked to the same promoter. Where the expressible sequence encodes three heterologous payloads, in some cases, the nucleotide sequences encoding the three heterologous payloads are operably linked to two or three different promoters. In some cases, the fourth polynucleotide construct of the present disclosure comprises two or more expressible sequences, each comprising a nucleotide sequence encoding a heterologous payload. [0296] In some embodiments, the expressible sequence encodes a polypeptide of interest. The polypeptide of interest may be any type of protein/peptide including, without limitation, an enzyme, an extracellular matrix protein, a receptor, transporter, ion channel, or other membrane protein, a hormone, a neuropeptide, an antibody, or a cytoskeletal protein; or a fragment thereof, or a biologically active domain of interest. In some cases, the payload is a therapeutic polypeptide, e.g., a polypeptide that provides clinical benefit. [0297] Where the payload is an interfering RNA (RNAi), suitable RNAi include RNAi that decrease the level of an apoptotic or angiogenic factor in a cell. For example, an RNAi may be an shRNA or siRNA that reduces the level of a payload that induces or promotes apoptosis in a cell. A payload may be a gene whose gene product induces or promotes apoptosis are referred to herein as “pro-apoptotic genes” and the products of those genes (mRNA; protein) are referred to as “pro-apoptotic gene products.” Pro-apoptotic gene products include, e.g., Bax, Bid, Bak, and Bad gene products. See, e.g., U.S. Patent No.7,846,730. In another example, the RNAi specifically reduces the level of an RNA and/or a polypeptide product of a defective allele. [0298] In some embodiments, the payload is an aptamer. In some cases, the aptamer is a therapeutic aptamer. For example, the aptamer may function as an antagonist by blocking interactions at a disease-associated target (e.g., receptor-ligand interactions). Alternatively, an aptamer may serve as an agonist for activating the function of a target receptor. Exemplary aptamers of interest include aptamers against growth factor receptors and growth factors such as aptamers that bind to epidermal growth factor receptor (see, e.g., Wang et al. (2014) Biochem. Biophys. Res. Commun.453(4):681-5), transforming growth factor-beta type III receptor (see, e.g., Ohuchi et al. (2006) Biochimie 88(7):897-904.), vascular endothelial growth factor (VEGF) (see, e.g., Ng et al. (2006) Nat. Rev. Drug Discovery 5:123; and Lee et al. (2005) Proc. Natl. Acad. Sci. USA 102:18902) or platelet-derived growth factor (PDGF), e.g., E10030 (see, e.g., Ni and Hui (2009) Ophthalmologica 223:401; and Akiyama et al. (2006) J. Cell Physiol. 207:407). [0299] In some embodiments, the expressible sequence encodes a sequence-specific endonuclease for use in genome editing. The sequence specific endonuclease may be used to create a double-stranded break at a specific site in the genome. The double stranded breaks may then be repaired by non-homologous end joining (NHEJ), microhomology-mediated end joining (MMEJ), or homology-directed repair (HDR) pathways. Desired genome edits may be introduced into the genome using donor DNA to repair double-strand breaks by homologous recombination. Various sequence-specific endonucleases may be used in genome editing for creation of double-strand breaks in DNA, including, without limitation, engineered zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), meganucleases, and clustered regularly interspaced short palindromic repeats (CRISPR) Cas9. See, e.g., Targeted Genome Editing Using Site-Specific Nucleases: ZFNs, TALENs, and the CRISPR/Cas9 System (T. Yamamoto ed., Springer, 2015); Genome Editing: The Next Step in Gene Therapy (Advances in Experimental Medicine and Biology, T. Cathomen, M. Hirsch, and M. Porteus eds., Springer, 2016); Aachen Press Genome Editing (CreateSpace Independent Publishing Platform, 2015); herein incorporated by reference. Precise control over the timing of production of the genome editing enzyme may be achieved by inducibly producing recombinant adenovirus associated virus (rAAV) virions with the vector system to allow turning on and off of expression as desired. [0300] In some cases, a payload of interest is a site-specific endonuclease that provides for site- specific knock-down of gene function, e.g., where the endonuclease knocks out an allele associated with a disease. For example, in a case where a dominant allele encodes a defective copy of a gene, and the wild-type gene provides for normal function, a site-specific endonuclease may be targeted to the defective allele and knock out the defective allele. In some cases, a site-specific endonuclease is an RNA-guided endonuclease. [0301] A site-specific nuclease may also be used to stimulate homologous recombination with a donor DNA that encodes a functional copy of the protein encoded by the defective allele. Thus, e.g., a subject rAAV virion may be used to deliver a site-specific endonuclease that knocks out a defective allele and also be used to deliver a functional copy of the defective allele, resulting in repair of the defective allele, thereby providing for production of a functional gene product. [0302] In some cases, the payload is an RNA-guided endonuclease. In some cases, the payload is an RNA comprising a nucleotide sequence encoding an RNA-guided endonuclease. In some cases, the payload is a guide RNA, e.g., a single-guide RNA. In some cases, the payloads are: 1) a guide RNA; and 2) an RNA-guided endonuclease. The guide RNA may comprise: a) a protein- binding region that binds to the RNA-guided endonuclease; and b) a region that binds to a target nucleic acid. An RNA-guided endonuclease is also referred to herein as a “genome editing nuclease.” [0303] Examples of RNA-guided endonucleases are CRISPR/Cas endonucleases (e.g., class 2 CRISPR/Cas endonucleases such as a type II, type V, or type VI CRISPR/Cas endonucleases). A suitable genome editing nuclease is a CRISPR/Cas endonuclease (e.g., a class 2 CRISPR/Cas endonuclease such as a type II, type V, or type VI CRISPR/Cas endonuclease). In some cases, a suitable RNA-guided endonuclease is a class 2 CRISPR/Cas endonuclease. In some cases, a suitable RNA-guided endonuclease is a class 2 type II CRISPR/Cas endonuclease (e.g., a Cas9 protein). In some cases, a genome targeting composition includes a class 2 type V CRISPR/Cas endonuclease (e.g., a Cpf1 protein, a C2c1 protein, or a C2c3 protein). In some cases, a suitable RNA-guided endonuclease is a class 2 type VI CRISPR/Cas endonuclease (e.g., a C2c2 protein; also referred to as a “Cas13a” protein). Also suitable for use is a CasX protein. Also suitable for use is a CasY protein. [0304] In some cases, the genome-editing endonuclease is a Type II CRISPR/Cas endonuclease. In some cases, the genome-editing endonuclease is a Cas9 polypeptide. The Cas9 protein is guided to a target site (e.g., stabilized at a target site) within a target nucleic acid sequence (e.g., a chromosomal sequence or an extrachromosomal sequence, e.g., an episomal sequence, a minicircle sequence, a mitochondrial sequence, a chloroplast sequence, etc.) by virtue of its association with the protein-binding segment of the Cas9 guide RNA. In some cases, the Cas9 polypeptide used in a composition or method of the present disclosure is a Staphylococcus aureus Cas9 (saCas9) polypeptide. In some cases, a suitable Cas9 polypeptide is a high-fidelity (HF) Cas9 polypeptide. Kleinstiver et al. (2016) Nature 529:490. In some cases, a suitable Cas9 polypeptide exhibits altered PAM specificity. See, e.g., Kleinstiver et al. (2015) Nature 523:481. In some cases, the genome-editing endonuclease is a type V CRISPR/Cas endonuclease. In some cases a type V CRISPR/Cas endonuclease is a Cpf1 protein. In some cases, the genome-editing endonuclease is a CasX or a CasY polypeptide. CasX and CasY polypeptides are described in Burstein et al. (2017) Nature 542:237. [0305] In some cases, a genome editing nuclease is a fusion protein that is fused to a heterologous polypeptide (also referred to as a “fusion partner”). In some cases, a genome editing nuclease is fused to an amino acid sequence (a fusion partner) that provides for subcellular localization, i.e., the fusion partner is a subcellular localization sequence (e.g., one or more nuclear localization signals (NLSs) for targeting to the nucleus, two or more NLSs, three or more NLSs, etc.). [0306] Also suitable for use is an RNA-guided endonuclease with reduced enzymatic activity. Such an RNA-guided endonuclease is referred to as a “dead” RNA-guided endonuclease; for example, a Cas9 polypeptide that comprises certain amino acid substitutions such that it exhibits substantially no endonuclease activity, but such that it still binds to a target nucleic acid when complexed with a guide RNA, is referred to as a “dead” Cas9 or “dCas9.” In some cases, a “dead” Cas9 protein has a reduced ability to cleave both the complementary and the non- complementary strands of a double stranded target nucleic acid. For example, a “nuclease defective” Cas9 lacks a functioning RuvC domain (i.e., does not cleave the non-complementary strand of a double stranded target DNA) and lacks a functioning HNH domain (i.e., does not cleave the complementary strand of a double stranded target DNA). Such a Cas9 protein has a reduced ability to cleave a target nucleic acid (e.g., a single stranded or double stranded target nucleic acid) but retains the ability to bind a target nucleic acid. A Cas9 protein that may not cleave target nucleic acid (e.g., due to one or more mutations, e.g., in the catalytic domains of the RuvC and HNH domains) is referred to as a “nuclease defective Cas9”, “dead Cas9” or simply “dCas9.” Other residues may be mutated to achieve the above effects (i.e. inactivate one or the other nuclease portions). [0307] In some cases, the genome-editing endonuclease is an RNA-guided endonuclease (and its corresponding guide RNA) known as Cas9-synergistic activation mediator (Cas9-SAM). The RNA-guided endonuclease (e.g., Cas9) of the Cas9-SAM system is a “dead” Cas9 fused to a transcriptional activation domain (wherein suitable transcriptional activation domains include, e.g., VP64, p65, MyoD1, HSF1, RTA, and SET7/9) or a transcriptional repressor domain (where suitable transcriptional repressor domains include, e.g., a KRAB domain, a NuE domain, an NcoR domain, a SID domain, and a SID4X domain). The guide RNA of the Cas9-SAM system comprises a loop that binds an adapter protein fused to a transcriptional activator domain (e.g., VP64, p65, MyoD1, HSF1, RTA, or SET7/9) or a transcriptional repressor domain (e.g., a KRAB domain, a NuE domain, an NcoR domain, a SID domain, or a SID4X domain). For example, in some cases, the guide RNA is a single-guide RNA comprising an MS2 RNA aptamer inserted into one or two loops of the sgRNA; the dCas9 is a fusion polypeptide comprising dCas9 fused to VP64; and the adaptor/functional protein is a fusion polypeptide comprising: i) MS2; ii) p65; and iii) HSF1. See, e.g., U.S. Patent Publication No.2016/0355797. [0308] Also suitable for use is a chimeric polypeptide comprising: a) a dead RNA-guided endonuclease; and b) a heterologous fusion polypeptide. Examples of suitable heterologous fusion polypeptides include a polypeptide having, e.g., methylase activity, demethylase activity, transcription activation activity, transcription repression activity, transcription release factor activity, histone modification activity, RNA cleavage activity, DNA cleavage activity, DNA integration activity, or nucleic acid binding activity. [0309] A nucleic acid that binds to a class 2 CRISPR/Cas endonuclease (e.g., a Cas9 protein; a type V or type VI CRISPR/Cas protein; a Cpf1 protein; etc.) and targets the complex to a specific location within a target nucleic acid is referred to herein as a “guide RNA” or “CRISPR/Cas guide nucleic acid” or “CRISPR/Cas guide RNA.” A guide RNA provides target specificity to the complex (the RNP complex) by including a targeting segment, which includes a guide sequence (also referred to herein as a targeting sequence), which is a nucleotide sequence that is complementary to a sequence of a target nucleic acid. [0310] In some cases, a guide RNA includes two separate nucleic acid molecules: an “activator” and a “targeter” and is referred to herein as a “dual guide RNA”, a “double-molecule guide RNA”, a “two-molecule guide RNA”, or a “dgRNA.” In some cases, the guide RNA is one molecule (e.g., for some class 2 CRISPR/Cas proteins, the corresponding guide RNA is a single molecule; and in some cases, an activator and targeter are covalently linked to one another, e.g., via intervening nucleotides), and the guide RNA is referred to as a “single guide RNA”, a “single-molecule guide RNA,” a “one-molecule guide RNA”, or simply “sgRNA.” [0311] In some cases, the guide RNA is at least partially complementary to a target RNA sequence and is capable of recruiting an ADAR enzyme for RNA editing of the target RNA sequence. [0312] Where the payload is an RNA-guided endonuclease or is both an RNA-guided endonuclease and a guide RNA, the payload may modify a target nucleic acid. In some cases, e.g., where a target nucleic acid comprises a deleterious mutation in a defective allele (e.g., a deleterious mutation in a neural cell target nucleic acid), the RNA-guided endonuclease/guide RNA complex, together with a donor nucleic acid comprising a nucleotide sequence that corrects the deleterious mutation (e.g., a donor nucleic acid comprising a nucleotide sequence that encodes a functional copy of the protein encoded by the defective allele), may be used to correct the deleterious mutation, e.g., via homology-directed repair (HDR). [0313] In some cases, the payloads are an RNA-guided endonuclease and 2 separate sgRNAs, where the 2 separate sgRNAs provide for deletion of a target nucleic acid via non-homologous end joining (NHEJ). [0314] In some cases, the payloads are: i) an RNA-guided endonuclease; and ii) one guide RNA. In some cases, the guide RNA is a single-molecule (or “single guide”) guide RNA (an “sgRNA”). In some cases, the guide RNA is a dual-molecule (or “dual-guide”) guide RNA (“dgRNA”). [0315] In some cases, the payloads are: i) an RNA-guided endonuclease; and ii) 2 separate sgRNAs, where the 2 separate sgRNAs provide for deletion of a target nucleic acid via non- homologous end joining (NHEJ). In some cases, the guide RNAs are sgRNAs. In some cases, the guide RNAs are dgRNAs. [0316] In some cases, the payloads are: i) a Cpf1 polypeptide; and ii) a guide RNA precursor; in these cases, the precursor may be cleaved by the Cpf1 polypeptide to generate 2 or more guide RNAs. [0317] The payloads as described herein may be flanked by ITRs.

[0330] In some embodiments, any combinations of the first promoter, the second promoter, the third promoter, the fourth promoter, and the fifth promoter are the same constitutive promoter or different constitutive promoters. [0331] In some embodiments, the first selectable marker, the second selectable marker, the third selectable marker, the fourth selectable marker, and the fifth selectable marker, or any combination thereof is an antibiotic resistance gene. In certain embodiments, the antibiotic resistance gene is a blasticidin resistance gene, a hygromycin resistance gene, or a puromycin resistance gene. [0332] In some embodiments, the first selectable marker, the second selectable marker, the third selectable marker, the fourth selectable marker, and the fifth selectable marker, or any combination thereof is a first split portion of an antibiotic resistance gene. In certain embodiments, the first split portion of the antibiotic resistance gene is a first split portion of the blasticidin resistance gene. [0333] In some embodiments, the first selectable marker, the second selectable marker, the third selectable marker, the fourth selectable marker, and the fifth selectable marker, or any combination thereof is a second split portion of an antibiotic resistance gene. In certain embodiments, the second split portion of the antibiotic resistance gene is a second split portion of the blasticidin resistance gene. [0334] In some embodiments, the first promoter, the second promoter, the third promoter, the fourth promoter, the fifth promoter, or any combination thereof, is an EF1alpha promoter or an attenuated version thereof. In some embodiments, the attenuated version comprises a mutation in the TATA box. In certain embodiments, the attenuated EF1alpha promoter has weaker promoter activity than an EF1alpha promoter. [0335] In some embodiments, the fourth polynucleotide comprising the sequence encoding the payload further comprises a spacer between the 5' ITR and the sequence encoding the fourth selectable marker or a spacer between the sequence encoding the fourth selectable marker and the 3' ITR, or a combination thereof.

[0336] In some embodiments, the fourth polynucleotide comprising the sequence encoding the payload further comprises a spacer between the 5' ITR and the sequence encoding the selectable marker or a spacer between the sequence encoding the fourth selectable marker and the 3' ITR, or a combination thereof. In some embodiments, the spacer ranges in length from 500 base pairs to 5000 base pairs. Selectable Marker [0337] In some embodiments, suitable markers include genes which confer resistance to antibiotics or toxins, or sensitivity, or impart color, or change the antigenic characteristics when cells, which have been transfected with the nucleic acid constructs, are grown in an appropriate selective medium. Exemplary selectable marker genes include, without limitation, the neomycin resistance gene (neo encoding aminoglycoside phosphotransferase (APH)) that allows selection in mammalian cells by conferring resistance to G418 (Geneticin), the hygromycin-B resistance gene (hygB encoding hygromycin-B-phosphotransferase (HPH)) that confers resistance to hygromycin-B, the puromycin resistance gene (pac encoding puromycin-N-acetyltransferase) that confers resistance to puromycin, Zeocin resistance gene (Sh bla encodes a protein that binds to Zeocin) that prevents Zeocin from binding DNA and damaging it, and the blasticidin resistance gene (BSD) that confers resistance to blasticidin. In addition, dihydrofolate reductase (DHFR)-based methotrexate (MTX) selection or glutamine synthetase (GS)-based methionine sulfoximine (MSX) selection may be used in mammalian cells. Other suitable markers and selection methods are known to those of skill in the art. [0338] In some embodiments, the selectable marker is an antibiotic resistance protein. In some embodiments, the selectable marker is a split selectable marker that allows for selection of cells retaining two different polynucleotides using a single selective pressure. In some embodiments, the antibiotic resistance protein is split into two portions that can associate to form a functional antibiotic resistance protein. A first portion of the antibiotic resistance protein is encoded by a first polynucleotide and a second portion of the antibiotic resistance protein is encoded by a second polynucleotide. In some embodiments, a split intervening proteins (inteins) system that permits stable retention of two integrated nucleic acid constructs under a single selective pressure is used. Inteins auto catalyze a protein splicing reaction that results in excision of the intein and joining of the flanking amino acids (extein sequences) via a peptide bond. Inteins exist in nature as a single domain within a host protein or, less frequently, in a split form. For split inteins, the two separate polypeptide fragments of the intein must associate in order for protein trans-splicing to occur to excise the intein. Split intein systems are described in: Cheriyan et al, J. Biol. Chem 288: 6202-6211 (2013); Stevens et al, PNAS 114: 8538-8543 (2017); Jillette et al., Nat Comm 10: 4968 (2019); US 2020/0087388 A1; and US 2020/0263197 A1.In some embodiments, a split intein is derived from the Nostoc punctiforme (Npu) DnaE intein, the Synechocystis species, strain PCC6803 (Ssp) DnaE intein, or the consensus DnaE intein (Cfa). In some embodiments, a first portion of the antibiotic resistance protein is the N- terminal portion which is fused to a N-terminal intein at the C-terminus and a second portion of the antibiotic resistance protein is the C-terminal portion which is fused to a C-terminal intein at the N-terminus. When both portions are present, the N-terminal intein associates with the C- terminal intein resulting in excision of the inteins and splicing of the C-terminus of the N- terminal portion of the antibiotic resistance protein to the N-terminus of the C-terminal portion of the antibiotic resistance protein, thereby forming a functional antibiotic resistance proteins. [0339] In some embodiments, the selectable marker is an auxotrophic selection element. In some embodiments, the auxotrophic selection element codes for an inactive protein that requires expression of a second auxotrophic selection element for activity. In some embodiments, the auxotrophic selection element codes for a C-terminal fragment of the auxotrophic protein Z-Cter and the second auxotrophic selection element codes for N-terminal fragment of an auxotrophic protein Z-Nter or vice a versa. In some embodiments, the auxotrophic selection element codes for DHFR Z-Cter and DHFR Z-Nter. In some embodiments, the auxotrophic selection element codes for a C-terminal fragment of the auxotrophic protein fused to a C-terminal intein of a split intein and the second auxotrophic selection element codes for an N-terminal fragment of an auxotrophic protein fused to an N-terminal intein of a split intein. In some embodiments, the auxotrophic selection element codes for C-terminal fragment of PAH, GS, TYMS, or DHFR fused to a C-terminal intein of a split intein. In some embodiments, the auxotrophic selection element codes for an N-terminal fragment of PAH, GS, TYMS, or DHFR fused to a N-terminal intein of a split intein. [0340] In certain embodiments, a split auxotrophic selection system that permits stable retention of two integrated nucleic acid constructs under a single selective pressure can be used. One construct encodes the N-terminal fragment of mammalian dihydrofolate reductase (DHFR) fused to a leucine zipper peptide (“Nter-DHFR”). This N-terminal fragment is enzymatically nonfunctional. The other construct encodes the C-terminal fragment of DHFR fused to a leucine zipper peptide (“Cter-DHFR”). This C-terminal fragment is enzymatically nonfunctional. When both fragments are concurrently expressed in the cell, a functional DHFR enzyme complex is formed through association of the leucine zipper peptides. Both constructs can be stably retained in the genome of a DHFR null cell by growth in a medium lacking hypoxanthine and thymidine.

In some embodiments, the selectable marker is a leucine zipper linked to an N-terminus of the antibiotic resistance protein or leucine zipper linked to a C-terminus of the antibiotic resistance protein. In some embodiments, the antibiotic resistance protein is for puromycin resistance or blasticidin resistance. In some embodiments, the split intein is derived from the Nostoc punctiforme (Npu) DnaE intein, the Synechocystis species, strain PCC6803 (Ssp) DnaE intein, or the consensus DnaE intein (Cfa). In some embodiments, an N-terminal intein comprises at least 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to SEQ ID NO: 140. In some embodiments, a C-terminal intein comprises at least 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to SEQ ID NO: 141. [0407] In some embodiments, the stuffer sequence further comprises a sequence coding for a selectable marker and a helper enzyme, wherein expression of the helper enzyme facilitates growth of the cell in conjunction with the selectable marker. In certain embodiments, the helper enzyme is an enzyme that facilitates production of a molecule required for cell growth. For example, the helper enzyme may be required for production of a cofactor utilized by the functional enzyme to generate the molecule required for cell growth. In certain embodiments, the cell may produce the helper enzyme at low levels and the expression of the helper enzyme from the helper construct can increase helper enzyme levels thereby increasing production of the molecule required for cell growth, by, e.g., increasing levels of a co-factor required for enzyme activity. In some embodiments, the stuffer sequence further encodes a helper enzyme involved in production of tyrosine from phenylalanine. In some embodiments, the helper enzyme facilitates PAH-mediated production of tyrosine from phenylalanine. In some embodiments, the helper enzyme catalyzes production a co-factor required by PAH for converting phenylalanine to tyrosine. In some embodiments, the helper enzyme is GTP cyclohydrolase I (GTP-CH1). In some embodiments, the helper enzyme comprises at least 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to SEQ ID NO: 99. In some embodiments, the GTP-CH1 produces the cofactor (6R)-5,6,7,8-tetrahydrobiopterin (BH4) that is required for conversion of phenylalanine to tyrosine. In some embodiments, expression of GTP-CH1 facilitates growth of the host cell in conjunction with functional PAH upon application of the single selective pressure. [0408] In some embodiments, a selectable marker comprises at least 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to SEQ ID NO: 90 – SEQ ID NO: 98, SEQ ID NO: 112 – SEQ ID NO: 131, SEQ ID NO: 137, or SEQ ID NO: 138. In some embodiments, the selectable marker and helper enzyme comprises at least 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to SEQ ID NO: 101 – SEQ ID NO: 109. [0409] A major advantage of the inducible polynucleotide constructs disclosed herein encoding for Rep and Cap include that upon stable integration into a mammalian cell line, expression of Rep and Cap is inducible even in the absence of a transfection agent or a plasmid. In some embodiments, the stable cell line populations disclosed herein are homogeneous. For example, at least 70%, at least 80%, at least 90%, at least 95%, or 100% of the stable cell population comprises the stably integrated polynucleotide construct encoding for Rep and Cap proteins. [0410] The second polynucleotide construct may include a Cap protein encoding sequence identical or substantially identical to the Cap protein encoding sequence present in the Rep/Cap encoding polynucleotide construct. The second polynucleotide construct may include a Cap protein encoding sequence identical or substantially identical to the Cap protein encoding sequence present in the Rep/Cap encoding polynucleotide construct, but the Cap protein encoding sequence is driven by an inducible promoter. The second polynucleotide construct may be referred to as an inducible Cap construct. The inducible promoter may be any inducible promoter that is described herein in the below Adenoviral Helper Construct(s) section and is activated by any triggering agent and activator as described herein in the below Adenoviral Helper Construct(s) section. In some embodiments, the inducible promoter is a Tet inducible promoter. In some embodiments, the Tet inducible promoter is activated when bound to Tet responsive activator protein, e.g., Tet-on 3G, in the presence of a trigger agent, such as doxycycline. In some embodiments, a polynucleotide encoding a sequence comprising an inducible promoter Cap protein sequence may have at least 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to SEQ ID NO: 148. The second polynucleotide construct may be provided as a plasmid. The plasmid may have at least 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to SEQ ID NO: 149. The second polynucleotide construct may be provided as a vector. Adenoviral Helper Construct(s) [0411] In some aspects, provided herein is a third polynucleotide construct (also referred to as Construct 3), which encodes for one or more adenoviral helper proteins. Construct 3 is also referred to as Ad helper/Cre construct. This third polynucleotide construct is also referred to as an inducible helper construct (e.g., Adenoviral Helper Construct provides one or more helper proteins selected from E1A, E1B, E2A and E4 absent from a host cell) to be used in production of rAAV virions. In some embodiments, the sequence encoding E4 is a sequence encoding E4orf6. In some embodiments, the elements of an inducible helper construct (e.g., one or more helper proteins selected from E1A, E1B, E2A and E4 absent from a host cell) are in one or more separate constructs to be used in production of rAAV virions. In some embodiments, the host cell provides, one, two, or three of the four helper proteins. For example, for a host cell expressing E1A and E1B, the adenoviral helper construct provides E2A and E4. For a host cell expressing E2A and E4, the adenoviral helper construct provides E1A and E1B. For a host cell expressing E1B, the adenoviral helper construct provides E1A, E2A and E4. For a host cell expressing E2A, the adenoviral helper construct provides E1B, E1A and E4. For a host cell expressing E4, the adenoviral helper construct provides E1B, E2A and E1A. For a host cell expressing E1A, E2A and E4, the adenoviral helper construct provides E1B. For a host cell expressing E1B, E1A and E4, the adenoviral helper construct provides E2A. For a host cell expressing E1B, E2A and E1A, the adenoviral helper construct provides E4. In some embodiments, E4 is E4orf6. [0412] In some embodiments, the sequences coding for E1A, E1B, E2A, and E4 are operably linked to separate promoters. In some embodiments, the sequences coding for E1A, E1B, E2A, and E4 are operably linked to one promoter. In some embodiments, the sequences coding for E1A, E1B, E2A, and E4 are operably linked, in any combination, to one promoter or separate promoters. The separate promoters can be the same promoters or different promoters. A combination of the separate promoters and the one promoter can be the same promoters or different promoters. The one promoter can be a native promoter, a constitutive promoter, or an inducible promoter. The separate promoters can be native promoters, constitutive promoters, inducible promoters, or any combination thereof. In some embodiments, the constitutive promoter is EF1alpha promoter or human cytomegalovirus promoter. In some embodiments, the inducible promoter is a tetracycline-inducible promoter, a cumate-inducible promoter, or an ecdysone-inducible promoter. For example, some the sequence coding for E1A and E1B are separated by an IRES sequence of P2A sequence and are operably linked to one promoter. In some embodiments, the sequence coding for E1A and E2A are separated by an IRES sequence of P2A sequence and are operably linked to one promoter. In some embodiments, the sequence coding for E1A and E4 are separated by an IRES sequence of P2A sequence and are operably linked to one promoter. In some embodiments, the sequence coding for E1B and E2A are separated by an IRES sequence of P2A sequence and are operably linked to one promoter. In some embodiments, the sequence coding for E1B and E4 are separated by an IRES sequence of P2A sequence and are operably linked to one promoter. In some embodiments, the sequence coding for E2A and E4 are separated by an IRES sequence of P2A sequence and are operably linked to one promoter. In some embodiments, the sequences coding for the helper proteins are in different orientations. In some embodiments, the sequences coding for the helper proteins are bidirectional. In some embodiments, the E1A is operably linked to a natural or constitutive promoter, E1B is operably linked to a natural or constitutive promoter, and E2A and E4 are downstream of an excisable element (e.g., a sequence flanked by recombination sites and comprising a stop signal) and constitutive promoter, wherein upon excision of the excisable element (e.g., by a recombinase), E2A and E4 are operably linked to the constitutive promoter. In some embodiments, the E1A is operably linked to a natural or constitutive promoter, E1B is operably linked to a natural or constitutive promoter, and E2A and E4 are downstream of an excisable element (e.g., a sequence flanked by recombination sites and comprising a stop signal) and inducible promoter, wherein upon excision of the excisable element (e.g., by a recombinase), E2A and E4 are operably linked to the inducible promoter. In some embodiments, the E2A is operably linked to a natural or constitutive promoter, E4 is operably linked to a natural or constitutive promoter, and E1A and E1B are downstream of an excisable element (e.g., a sequence flanked by recombination sites and comprising a stop signal) and constitutive promoter, wherein upon excision of the excisable element (e.g., by a recombinase), E1A and E1B are operably linked to the constitutive promoter. In some embodiments, the E2A is operably linked to a natural or constitutive promoter, E4 is operably linked to a natural or constitutive promoter, and E1A and E1B are downstream of an excisable element (e.g., a sequence flanked by recombination sites and comprising a stop signal) and inducible promoter, wherein upon excision of the excisable element (e.g., by a recombinase), E1A and E1B are operably linked to the inducible promoter. [0413] In certain embodiments, the adenoviral helper construct provides inducible production of one or more of the helper proteins. In some embodiments, an adenoviral helper protein further comprises a protein tag. A protein tag can be a FLAG tag. In some embodiments, E2A is a FLAG tagged E2A. In some embodiments, E4 is a FLAG tagged E4. A protein tag, such as a FLAG tag, can be used to screen for or to confirm integration of the third polynucleotide construct and expression of the adenoviral helper protein from the third polynucleotide construct in a cell after induction. [0414] In some embodiments, the third integrated synthetic construct comprises conditionally expressible recombinase and conditionally expressible adenovirus helper proteins. In some embodiments, the third synthetic construct comprises conditionally expressible recombinase and conditionally expressible adenovirus helper proteins. In some embodiments, the one or more separate integrated constructs comprises conditionally expressible recombinase and conditionally expressible adenovirus helper proteins. In some embodiments, the one or more separate constructs comprises conditionally expressible recombinase and conditionally expressible adenovirus helper proteins. In some embodiments, the third integrated synthetic construct comprises conditionally expressible Cre recombinase and conditionally expressible adenovirus helper proteins. In the exemplary embodiments illustrated in FIG.1A and FIG.2A, prior to the cell being contacted with at least a third triggering agent, the third integrated construct comprises, from 5’ to 3’: an inducible promoter, a Cre coding sequence, a first polyA sequence, adenoviral helper protein coding sequences, a second polyA sequence, a constitutive promoter, a coding sequence for a protein that is responsive to the first triggering agent, and a second mammalian cell selection element. [0415] In typical embodiments, the Cre coding sequence is operatively linked to the inducible promoter. Various inducible promoters suitable for controlling expression of the Cre coding sequence and the Cap proteins coding sequences are described throughout the specification, e.g., in the section “Inducible Promoters”. In various embodiments, the inducible promoter comprises an element responsive to the third triggering agent. In some embodiments, the inducible promoter contains a regulatory sequence that allows for control of the promoter. The regulatory sequence can be operably linked to the promoter and positioned upstream of the promoter. Such regulatory sequences are known to those of skill in the art, and examples include those which cause the expression of a gene to be turned on or off in response to a chemical or physical stimulus, including the presence of a regulatory compound. The regulatory sequence used to control expression may be endogenous or exogenous to the host cell. In some embodiments, bacterial gene control elements in combination with viral transactivator proteins are used to provide mammalian inducible expression. Examples of mammalian-compatible regulatory sequences include those capable of controlling an engineered promoter to adjust transcription in response to antibiotics including, without limitation, tetracyclines, streptogramins, and macrolides.

[0416] In some embodiments, a bacterial tetracycline response element (TRE) is included in a construct to allow mammalian expression to be induced by tetracycline or a derivative thereof (e.g., doxycycline). In certain embodiments, the inducible promoter comprises a plurality of tetracycline (Tet) operator elements capable of binding to a Tet responsive activator protein in the presence of a tetracycline. In some embodiments, the plurality of tetracycline (Tet) operator elements form a Tetracycline Responsive element (TRE). In some embodiments, the TRE comprises seven repeats of a 19 base pair operator sequence. In further embodiments, the TRE comprises seven repeats of a 19 base pair operator sequence upstream of a minimal CMV promoter sequence. [0417] In some embodiments, a Tet responsive activator protein comprises an amino acid sequence having at least 90% identity (e.g., at least 95% or 100% identity) to the amino acid sequence: [0418] MSRLDKSKVINSALELLNGVGIEGLTTRKLAQKLGVEQPTLYWHVKNKRALLD ALPIEMLDRHHTHFCPLEGESWQDFLRNNAKSFRCALLSHRDGAKVHLGTRPTEKQYE TLENQLAFLCQQGFSLENALYALSAVGHFTLGCVLEEQEHQVAKEERETPTTDSMPPLL RQAIELFDRQGAEPAFLFGLELIICGLEKQLKCESGGPADALDDFDLDMLPADALDDFD LDMLPADALDDFDLDMLPG (SEQ ID NO:40).

[0513] The Tet responsive activator protein or variant thereof, the Tet Repressor binding protein or variant thereof, TRE sequence, or any tetracycline-inducible promoter sequence or variant thereof can be any of those disclosed in US 7,541,446; US 8,383,364; US 6,136,954; US 5,814,618; US 6,271,348; US 5,789,156; US 7,666,668; US 6,914,124; US 5,650,298; US 5,922,927; US 5,464,758; US 5,866,755; US 5,589,362; US 5,654,168; US 6,242,667; US 5,912,411; US 6,783,756; US 5,888,981; US 6,004,941; US 6,252,136; US 5,859,310; US 6,271,341; US 6,087,166; US2003022315; US20050037335; US 9,181,556; and WO03056021, which are each herein incorporated by reference in their entirety. [0514] Any of the proteins described herein may be expressed from a nucleotide sequence that has been codon-optimized to increase expression in a host cell, e.g., a mammalian cell or a human cell line. [0515] In other embodiments, an insect gene control element is used to provide mammalian inducible expression. For example, an ecdysone-responsive element and a gene encoding the ecdysone receptor can be included in a construct to allow mammalian expression to be induced by the insect hormone ecdysone or analogs or derivatives thereof, such as ponasterone. In mammalian cells, the ecdysone receptor heterodimerizes with the retinoid X receptor (RXR). The ecdysone-responsive element comprises a binding site for the RXR-ecdysone receptor heterodimer, which is typically a synthetic recognition site for the heterodimer that preferably does not bind any endogenous transcription factors or natural nuclear hormone receptors. In the presence of ecdysone or an analog or derivative thereof, the RXR-ecdysone receptor heterodimer binds to the ecdysone-responsive element to activate transcription from the promoter. For a description of ecdysone-responsive promoters, see, e.g., No et al. (1996) Proc. Natl. Acad. Sci. USA 93(8):3346-51, Oehme et al. (2006) Cell Death and Differentiation (2006) 13:189-201; herein incorporated by reference. [0516] In some embodiments, the third construct or an additional separate construct comprises an element responsive to a fourth triggering agent. In certain embodiments, the fourth triggering agent-responsive element comprises a plurality of hormone-response elements. In particular embodiments, the hormone-response elements are estrogen responsive elements (EREs). In various embodiments, the third triggering agent is the same as the first triggering agent, and the fourth triggering agent is the same as the second triggering agent. [0517] In some embodiments, the inducible promoter comprises a plurality of Tet operator elements capable of binding to a Tet responsive activator protein in the presence of a third triggering agent. In particular embodiments, the third triggering agent is the same as the first triggering agent. [0518] In some embodiments, the recombinase coding sequence is flanked by a first recombinase site and a second recombinase site. In some embodiments, the recombinase is Cre. In some embodiments, the Cre coding sequence is flanked by a first lox site and a second lox site. In some embodiments, the first polyA sequence is positioned between the Cre coding sequence and adenoviral helper protein coding sequences that encode one or both of adenovirus E2A and E4. The strong 3’ polyadenylation signal positioned upstream (5’ to) the coding sequences for the adenovirus helper proteins prevents basal expression of the downstream adenoviral helper genes, E2A and E4. [0519] In some embodiments, helper construct does not comprise a recombinase that is self- excising. In some embodiments, the recombinase is a site-specific recombinase. In some embodiments, the recombinase is fused to a ligand binding domain. In some embodiments, the recombinase is Cre polypeptide or flippase polypeptide. In some embodiments, the Cre polypeptide is fused to a ligand binding domain. In some embodiments, the ligand binding domain is a hormone receptor. In some embodiments, the hormone receptor is an estrogen receptor. In some embodiments, the estrogen receptor comprises a point mutation. In some embodiments, the estrogen receptor is ERT2. In some embodiments, the recombinase is a Cre- ERT2 polypeptide. In some embodiments, the recombinase translocates to the nucleus in the presence of a triggering agent. In some embodiments, the triggering agent is an estrogen receptor ligand. In some embodiments, the triggering agent is a selective estrogen receptor modulator (SERM). In some embodiments, the triggering agent is tamoxifen. When the recombinase is not self-excisable, the sequence or sequences encoding one or more helper proteins can be operably linked to an inducible promoter. When the recombinase is not self-excisable, the sequence or sequences encoding one or more helper proteins can be downstream of an excisable element (e.g., a sequence flanked by recombination sites and comprising a stop signal) and constitutive promoter, wherein upon excision of the excisable element (e.g., by a recombinase), the sequence or sequences encoding one or more helper proteins are operably linked to the constitutive promoter. [0520] In some embodiments, the further segment shown in FIG.1A provides for inducible production of VA-RNA from construct 3. [0521] In this embodiment, the further segment includes a Cre-inducible U6 or U7 promoter. The U6 or U7 promoter is split into 2 parts separated by a Lox flanked stuffer sequence. The U6 or U7 promoter is inactive because of the presence of the stuffer sequence. Cre mediated excision of the stuffer activates the U6 or U7 promoter. The U6 or U7 promoter drives the expression of transcriptionally dead mutants of VA-RNA1 (a preferred embodiment is a double point mutant G16A- G60A). Other embodiments provide for alternative sources of VA-RNA. [0522] In various embodiments, the coding sequence for the first triggering agent-responsive protein is operatively linked to a CMV promoter. In some embodiments, the coding sequence for the first triggering agent-responsive protein comprises a coding sequence for the Tet responsive activator protein. In particular embodiments, the Tet responsive activator protein is Tet-on 3G activator protein. [0523] In various embodiments, the second mammalian cell selection element confers antibiotic resistance. In particular embodiments, the antibiotic resistance conferring element is a blasticidin resistance gene. [0524] Multiple inducible helper polynucleotide constructs are contemplated herein. In some embodiments, the elements of the inducible helper polynucleotide constructs can be in one or more separate constructs. In some embodiments, said inducible helper polynucleotide constructs encode for one or more adenoviral helper proteins, such as VA-RNA, E2A, E4, or any combination thereof. In some embodiments, the present disclosure provides for an inducible polynucleotide construct encoding for a mutated VA-RNA gene sequence. In some embodiments, the mutations to VA-RNA render its internal promoters inactive. For example, the inducible helper polynucleotide construct may comprise from 5’ to 3’ a first part of a U6 promoter sequence, a first lox sequence, a stuffer sequence, a second lox sequence, and a second part of a U6 promoter sequence. The stuffer sequence may be any polynucleotide sequence and is excised by Cre. Cre may be exogenously provided, such as in the form of Cre gesicles. Cre may also be encoded for in the same inducible helper polynucleotide construct and expression of Cre may be conditioned on the presence of at least two triggering agents, such as doxycycline and tamoxifen. Cre may be a hormone activated Cre. [0525] In other embodiments, instead of a mutated VA-RNA gene sequence, the inducible helper constructs may comprise a constitutively expressed VA-RNA that is not mutated. [0526] In some embodiments, the inducible helper polynucleotide construct also encodes for one or more helper proteins, a self-excising element upstream of the one or more helper proteins, and an inducible promoter upstream of the self-excising element. Expression of the self-excising element may be driven by a Tet-on 3G system. For example, the construct may comprise a Tet- On 3G gene sequence, wherein expression is driven by an EF1alpha promoter. The EF1alpha promoter may be a mutated EF1alpha promoter. The mutated EF1alpha promoter can have a sequence of: ggatctgcgatcgctccggtgcccgtcagtgggcagagcgcacatcgcccacagtccccgagaagttggggggaggggtcggcaattg aacgggtgcctagagaaggtggcgcggggtaaactgggaaagtgatgtcgtgtactggctccgcctttttcccgagggtgggggagaac cgtatgtaagtgcagtagtcgccgtgaacgttctttttcgcaacgggtttgccgccagaacacagctgaagcttcgaggggctcgcatctctc cttcacgcgcccgccgccctacctgaggccgccatccacgccggttgagtcgcgttctgccgcctcccgcctgtggtgcctcctgaactgc gtccgccgtctaggtaagtttaaagctcaggtcgagaccgggcctttgtccggcgctcccttggagcctacctagactcagccggctctcca cgctttgcctgaccctgcttgctcaactctacgtctttgtttcgttttctgttctgcgccgttacagatccaagctgtgaccggcgcctac (SEQ ID NO: 20). [0527] In the presence of a first triggering agent, such as doxycycline, Tet-On 3G is able to bind the Tet inducible promoter. Upon this binding event, the Tet inducible promoter drives expression of the self-excising element. In some embodiments, the self-excising element is a hormone activated Cre. In the presence of a second triggering agent, such as tamoxifen, and upon expression of Cre, Cre self-excises itself leading to expression of downstream adenoviral helper proteins. Thus, mammalian cell lines stably integrated with the inducible helper constructs disclosed herein only express adenoviral helper proteins in the presence of at least two triggering agents (e.g., doxycycline and tamoxifen). [0528] In some embodiments, an inducible helper construct is a polynucleotide construct coding for: a) one or more helper proteins; and b) a self-excising element upstream of the one or more helper proteins. In some embodiments, the self-excising element is operably linked to a constitutive promoter. In some embodiments, the constitutive promoter is EF1alpha promoter or human cytomegalovirus promoter. In some embodiments, a sequence coding for the self- excising element comprises a poly A sequence. In some embodiments, the self-excising element is a recombinase. In some embodiments, the recombinase is a site-specific recombinase. In some embodiments, the recombinase is fused to a ligand binding domain. In some embodiments, the recombinase is Cre polypeptide or flippase polypeptide. In some embodiments, the Cre polypeptide is fused to a ligand binding domain. In some embodiments, the ligand binding domain is a hormone receptor. In some embodiments, the hormone receptor is an estrogen receptor. In some embodiments, the estrogen receptor comprises a point mutation. In some embodiments, the estrogen receptor is ERT2. In some embodiments, the recombinase is a Cre- ERT2 polypeptide. In some embodiments, the self-excising element translocates to the nucleus in the presence of a triggering agent. In some embodiments, the triggering agent is an estrogen receptor ligand. In some embodiments, the triggering agent is a selective estrogen receptor modulator (SERM). In some embodiments, the triggering agent is tamoxifen. In some embodiments, the recombinase is flanked by recombination sites. In some embodiments, the recombination sites are lox sites or flippase recognition target (FRT) sites. In some embodiments, the lox sites are loxP sites. In some embodiments, the self-excising element is excised upon administration of the triggering agent, thereby operably linking the constitutive promoter to the one or more helper proteins. In some embodiments, the inducible helper construct lacks sequences coding for a tetracycline inducible system (e.g., a tetracycline- responsive promoter element (TRE) and/or a reverse tetracycline-controlled transactivator (rTA)). In some embodiments, the inducible helper construct lacks sequences coding for a tetracyline-inducible system, an ecdysone-inducible system, or a cumate-inducible system. [0529] In some embodiments, an inducible helper construct is a polynucleotide construct coding for: a) one or more helper proteins; b) a self-excising element upstream of the one or more helper proteins; and c) an inducible promoter upstream of the self-excising element. In some embodiments, the self-excising element is operably linked to the inducible promoter. In some embodiments, expression of the self-excising element is driven by the inducible promoter. [0530] In some embodiments, an inducible helper construct is a polynucleotide construct coding for: a) one or more helper proteins; b) a recombinase; and c) an inducible promoter upstream of the one or more helper proteins; and d) an inducible promoter upstream the recombinase. In some embodiments, the recombinase is operably linked to the inducible promoter. In some embodiments, the one or more helper proteins are operably linked to the inducible promoter. In some embodiments, expression of the recombinase is driven by the inducible promoter. In some embodiments, expression of the one or more helper proteins is driven by the inducible promoter. [0531] In some embodiments, the inducible promoter is a tetracycline-responsive promoter element (TRE). In some embodiments, the TRE comprises Tet operator (tetO) sequence concatemers fused to a minimal promoter. In some embodiments, the minimal promoter is a human cytomegalovirus promoter. In some embodiments, the minimal promoter comprises a sequence having at least 70%, 80%, 90%, 95%, 99%, or 100% sequence identity to any one of SEQ ID NOs: 63-68. In some embodiments, the inducible promoter comprises a sequence having at least 70%, 80%, 90%, 95%, 99%, or 100% sequence identity to any one of SEQ ID NOs: 22, 46-48, or 50-62.

Synthetic nucleic acid constructs [0553] In typical embodiments, the nuclear genome of the cell of the stable cell line comprises a plurality of integrated synthetic nucleic acid constructs. In some embodiments, each of the plurality of synthetic nucleic acid constructs is separately integrated into the nuclear genome of the cell. In some embodiments, only a single non-auxotrophic selection is required to maintain all of the plurality of synthetic nucleic acid constructs stably within the nuclear genome of the cells. In some embodiments, antibiotic resistance is required to maintain the plurality of synthetic constructs stably within the nuclear genomes of the cells. In some embodiments, both a non-auxotrophic selection and antibiotic resistance is required to maintain the plurality of synthetic constructs stably within the nuclear genomes of the cells. In some embodiments, auxotrophic selection and antibiotic resistance is required to maintain the plurality of synthetic constructs stably within the nuclear genomes of the cells. In some embodiments, auxotrophic selection is required to maintain the plurality of synthetic constructs stably within the nuclear genomes of the cells. [0554] In particular embodiments, the first integrated synthetic construct comprises conditionally expressible AAV Rep and Cap coding sequences; the second integrated synthetic construct comprises a conditionally expressible AAV Cap coding sequence, where the AAV Cap coding sequence is operably linked to a native or an inducible promoter; the third integrated synthetic construct comprises a conditionally expressible Cre coding sequence and conditionally expressible adenoviral helper protein coding sequences; and the fourth integrated synthetic construct comprises expressible coding sequences for the payload. An example of this embodiment is depicted in FIG.1A. [0555] In particular embodiments, the first integrated synthetic construct comprises conditionally expressible AAV Rep and Cap coding sequences, where the AAV Cap coding sequence is operably linked to an inducible promoter; the second integrated synthetic construct comprises a conditionally expressible Cre coding sequence and conditionally expressible adenoviral helper protein coding sequences; and the third integrated synthetic construct comprises expressible coding sequences for the payload. An example of this embodiment is depicted in FIG.2A. Production of Single-Stranded or Self-Complementary rAAV Virion DNA [0556] In some embodiments, the region of the fourth polynucleotide construct between the two inverted terminal repeats (3’ ITR and 5’ ITR) is packaged into rAAV virions. In some embodiments, the rAAV virions comprise wild-type inverted terminal repeats, wherein the rAAV virion DNA that is generated is single-stranded (i.e., ssAAV virion). In other embodiments, a terminal resolution site in the 3' ITR is deleted, resulting in formation of an rAAV virion comprising DNA that is self-complementary (i.e., scAAV virion). The scAAV forms a single-stranded DNA molecule during replication in which two single-stranded genomes comprising a plus DNA strand and a minus DNA strand are concatenated to form a self- complementary intramolecular dsDNA genome. Unlike ssAAV virions, the scAAV virions do not need to perform second-strand DNA synthesis, which increases the efficiency of scAAV transgene expression relative to ssAAV. However, the maximum cargo capacity of scAAV (i.e., maximum length of region between the 5' ITR and 3' ITR of the fourth polynucleotide construct) that can be packaged into the rAAV virion is about half that of ssAAV because the scAAV DNA packaged into a viral particle is a concatemer of two single-stranded genomes of opposite strands. For a description of methods of producing scAAV virions, see, e.g., Raj et al. (2011) Expert Rev. Hematol.4(5):539-549, McCarty (2008) Mol. Ther.16(10):1648-1656, McCarty et al. (2003) Gene Ther.10(26):2112-2118; herein incorporated by reference in their entireties. For example, a ssAAV plasmid encoding a sequence of a payload (e.g., construct 3 of FIG.2A) can be SEQ ID NO: 159. For example, a scAAV plasmid encoding a sequence of a payload (e.g., construct 3 of FIG.2A) can be SEQ ID NO: 157. Split Auxotrophic selection [0557] In some embodiments, maintaining constructs stably in the cellular genome requires selective pressure. [0558] Typically, each integrated nucleic acid construct comprises a mammalian cell selection element. In some embodiments, the stable cell line comprises four integrated nucleic acid constructs, wherein the first nucleic acid construct comprises a first mammalian cell selection element, the second nucleic acid construct comprises a second mammalian cell selection element, the third nucleic acid construct comprises a third mammalian cell selection element and the fourth nucleic acid construct comprises a fourth mammalian cell selection element. In some embodiments, the stable cell line comprises three integrated nucleic acid constructs, wherein the first nucleic acid construct comprises a first mammalian cell selection element, the second nucleic acid construct comprises a second mammalian cell selection element, and the third nucleic acid construct comprises a third mammalian cell selection element. [0559] In some embodiments, the mammalian selection elements are components of a split auxotrophic selection system or a split antibiotic resistance gene. [0560] In some embodiments, a split auxotrophic system can be a leucine zipper based system that permits stable retention of two integrated nucleic acid constructs under a single selective pressure. In some embodiments, components of the split auxotrophic selection system described herein comprise a C-terminal fragment of the auxotrophic protein Z-Cter and an N-terminal fragment of an auxotrophic protein Z-Nter. In some embodiments, a split auxotrophic system is a split intervening proteins (inteins) system that permits stable retention of two integrated nucleic acid constructs under a single selective pressure. Inteins auto catalyze a protein splicing reaction that results in excision of the intein and joining of the flanking amino acids (extein sequences) via a peptide bond. Inteins exist in nature as a single domain within a host protein or, less frequently, in a split form. For split inteins, the two separate polypeptide fragments of the intein must associate in order for protein trans-splicing to occur to excise the intein. Split intein systems are described in: Cheriyan et al, J. Biol. Chem 288: 6202-6211 (2013); Stevens et al, PNAS 114: 8538-8543 (2017); Jillette et al., Nat Comm 10: 4968 (2019); US 2020/0087388 A1; and US 2020/0263197 A1. In some embodiments, components of the split auxotrophic selection system described herein comprises a construct encoding an N-terminal fragment of an auxotrophic protein fused to an N-terminal intein of the split intein and a construct encoding the C-terminal fragment of the auxotrophic protein fused to a C-terminal intein of the split intein. This N-terminal fragment is enzymatically nonfunctional and this C-terminal fragment is enzymatically nonfunctional. When both fragments are concurrently expressed in the cell, the split inteins can catalyze the joining of the N-terminal fragment of the auxotrophic protein and a C-terminal fragment of the auxotrophic protein to form a functional enzyme, such as any one of the enzymes disclosed herein (e.g., PAH, GS, TYMS, DHFR). In some embodiments, both constructs can be stably retained in the genome of a cell by growth in a medium lacking the product produced by the enzyme. [0561] In some embodiments, a construct encoding for a component of a split auxotrophic system further encodes a helper enzyme, wherein expression of the helper enzyme facilitates growth of the host cell in conjunction with the functional enzyme upon application of the single selective pressure.

Host production cell [0589] The present disclosure further provides host cells comprising the vector system described herein. A subject host cell can be an isolated cell, e.g., a cell in in vitro culture. A subject host cell is useful for producing rAAV virions, as described below. A subject host cell useful for producing rAAV virions can be any cell that is capable of expressing proteins from a p5 promoter. Where a subject host cell is used to produce rAAV virions, it is referred to as a “packaging cell.” In some cases, a subject host cell is stably genetically modified with the vector system. In other cases, a subject host cell is transiently genetically modified with the vector system. [0590] In some aspects, vector systems that comprise the first polynucleotide described herein; the second polynucleotide described herein; the third polynucleotide described herein; and the fourth polynucleotide described herein are provided. [0591] In some aspects, vector systems that comprise the first polynucleotide described herein; the second polynucleotide described herein; the third polynucleotide described herein; the fourth polynucleotide described herein; and the fifth polynucleotide described herein are provided. [0592] In some aspects, vector systems that comprise the first polynucleotide described herein; the second polynucleotide described herein; the third polynucleotide described herein; the fourth polynucleotide described herein; the fifth polynucleotide described herein; and the sixth polynucleotide described herein are provided. [0593] The vector system described herein can be used in a variety of host cells for rAAV virion production. For example, suitable host cells that have been transfected with the vector system are rendered capable of producing rAAV virions. The first, second, third and fourth polynucleotide constructs of the vector system can be introduced into a host cell, either simultaneously or serially, using established transfection techniques, including, but not limited to, electroporation, calcium phosphate precipitation, liposome-mediated transfection, and the like. In some embodiments, the first, second, and third polynucleotide constructs of the vector system are introduced into a host cell, and the fourth polynucleotide construct comprising the expressible payload is introduced later when production of the payload is desired. [0594] A subject host cell is generated by introducing the vector system into any of a variety of cells, e.g., mammalian cells, including, without limitation, murine cells, and primate cells (e.g., human cells). Suitable mammalian cells include, but are not limited to, primary cells and cell lines, where suitable cell lines include, but are not limited to, 293 cells, COS cells, HeLa cells, Vero cells, 3T3 mouse fibroblasts, C3H10T1/2 fibroblasts, CHO cells, and the like. Non- limiting examples of suitable host cells include, e.g., HeLa cells (e.g., American Type Culture Collection (ATCC) No. CCL-2), CHO cells (e.g., ATCC Nos. CRL9618, CCL61, CRL9096), 293 cells (e.g., ATCC No. CRL-1573), Vero cells, NIH 3T3 cells (e.g., ATCC No. CRL-1658), Huh-7 cells, BHK cells (e.g., ATCC No. CCL10), PC12 cells (ATCC No. CRL1721), COS cells, COS-7 cells (ATCC No. CRL1651), RAT1 cells, mouse L cells (ATCC No. CCLI.3), human embryonic kidney (HEK) cells (ATCC No. CRL1573), HLHepG2 cells, and the like. A subject host cell can also be made using a baculovirus to infect insect cells such as Sf9 cells, which produce AAV (see, e.g., U.S. Patent Nos.7,271,002 and 8,945,918). In some embodiments, a host cell is any cell capable of activating a p5 promoter of sequence encoding a Rep protein. [0595] In typical embodiments, the production host cell is a mammalian cell line that expresses adenovirus E1A and E1B. In particular embodiments, the cell is a human embryonic kidney (HEK) 293 cell line or derivatives thereof (HEK293T cells, HEK293F cells), a human HeLa cell line that expresses E1A and E1B, a Chinese hamster ovary (CHO) cell line that expresses E1A and E1B, or a Vero cell that expresses adenovirus E1A and E1B. In particular embodiments, the host cell is a HEK293 cell line. [0596] In certain embodiments, the host cell is or is genetically altered to be deficient in an enzyme required for production of a molecule required for cell growth, for example, an enzyme required for catalyzing production of a cofactor or nutrient. In certain embodiments, the host cell is DHFR null. In specific embodiments, the host cell is a DHFR null HEK293 cell. In some embodiments, the host cell is GS null. In some embodiments, the host cell is a GS null HEK293. [0597] In some embodiments, the host cell expresses or is genetically modified to express GTP- CH1. [0598] In some embodiments, the HEK293 cell expresses AAV E1A and E1B. In the presence of doxycycline and tamoxifen, the ER2 Cre is excised from the first integrated synthetic construct, thereby permitting expression of AAV E2A and E4. The self-excised ER2 Cre recombines by virtue of the lox sites flanking the EGFP cassette in the second integrated synthetic construct, thereby removing the EGFP segment from the second spacer element in the integrated second synthetic construct. As such, any cells comprising only the second integrated synthetic construct will be EGFP signal positive whereas cells comprising both the first and second integrated synthetic constructs will be EGFP signal negative, following the addition of the triggering agents. Absence of EGFP signal indicates successful transfection of both the first and second integrated synthetic constructs in a cell. This is further ensured by antibiotic resistance selection, e.g., blasticidin resistance. [0599] Additionally, removal of the EGFP cassette provides for the functional expression of Rep and Cap proteins, which can be linked to a first selectable marker, e.g., a first DHFR selection element, e.g., Z-Cter DHFR. The first selectable marker is capable of associating with a second selectable marker, e.g., a second DHFR selection element, e.g., a Z-Cter DHFR is capable of associating with a second DHFR selection element, e.g., Z-Nter DHFR, present in the fourth integrated synthetic construct to form an active molecule that allows the cell to survive in a selection medium, e.g., HT lacking media selection. The first selectable marker and second selectable marker can be any selectable marker as described herein, wherein expression of the first selectable marker and expression of the second selectable marker form an active molecule (e.g., a functional enzyme) that allows the cell to survive in a selection medium (e.g., a selection media deficient in the product produced by the functional enzyme). [0600] In some embodiments, the fourth integrated synthetic construct comprises a payload. The payload can be a guide RNA, an HDR homology region, or a gene of interest. [0601] In some embodiments, one or more of the synthetic nucleic acid constructs are integrated into the genome of a production host cell. In some embodiments, the integration of a construct into a chromosome is site-specific. Any method known in the art for directing integration into the genome may be used. For example, a polynucleotide construct can be cloned into a lentivirus vector that integrates into the nuclear genome of the cell. Alternatively, a transposon system, a clustered regularly interspersed short palindromic repeats (CRISPR) system, or a site-specific recombinase can be used to integrate a polynucleotide construct into the host cell genome, as described further below. [0602] In some embodiments, a polynucleotide construct is integrated into the genome using a transposon system comprising a transposase and transposon donor DNA. The transposase can be provided to a host cell with an expression vector or mRNA comprising a coding sequence encoding the transposase. The transposon donor DNA can be provided with a vector comprising transposon terminal inverted repeats (TIRs). The polynucleotide construct is cloned into the transposon donor vector between the TIRs. The host cell is cotransfected with an expression vector or mRNA encoding the transposase and the transposon donor vector containing the polynucleotide construct insert, wherein the polynucleotide construct is excised from the transposon donor vector and integrated into the genome of the host cell at a target transposon insertion site. Transposition efficiency may be improved in a host cell by codon optimization of the transposase, using engineered hyperactive transposases, and/or introduction of mutations in the transposon terminal repeats. Any suitable transposon system can be used including, without limitation, the piggyBac, Tol2, or Sleeping Beauty transposon systems. For a description of various transposon systems, see, e.g., Kawakami et al. (2007) Genome Biol.8 Suppl 1(Suppl 1):S7, Tipanee et al. (2017) Biosci Rep.37(6):BSR20160614, Yoshida et al. (2017) Sci Rep. 7:43613, Yusa et al. (2011) Proc. Natl. Acad. Sci. USA 108(4):1531-1536, Doherty et al. (2012) Hum. Gene Ther.23(3):311-320; herein incorporated by reference in their entireties. [0603] In some embodiments, a construct is integrated at a target chromosomal locus by homologous recombination using site-specific nucleases or site-specific recombinases. For example, a construct can be integrated into a double-strand DNA break at the target chromosomal site by homology-directed repair. A DNA break may be created by a site-specific nuclease, such as, but not limited to, a Cas nuclease (e.g., Cas9, Cpf1, or C2c1), an engineered RNA-guided FokI nuclease, a zinc finger nuclease (ZFN), a transcription activator-like effector- based nuclease (TALEN), a restriction endonuclease, a meganuclease, a homing endonuclease, and the like. Any site-specific nuclease that selectively cleaves a sequence at the target site for integration of the construct may be used. See, e.g., Targeted Genome Editing Using Site-Specific Nucleases: ZFNs, TALENs, and the CRISPR/Cas9 System (T. Yamamoto ed., Springer, 2015); Genome Editing: The Next Step in Gene Therapy (Advances in Experimental Medicine and Biology, T. Cathomen, M. Hirsch, and M. Porteus eds., Springer, 2016); Aachen Press Genome Editing (CreateSpace Independent Publishing Platform, 2015); herein incorporated by reference in their entireties. [0604] The construct sequence to be integrated is flanked by a pair of homology arms responsible for targeting the construct to the target chromosomal locus. A 5' homology arm that hybridizes to a 5' genomic target sequence and a 3' homology arm that hybridizes to a 3' genomic target sequence can be introduced into a polynucleotide construct. The homology arms are referred to herein as 5' and 3' (i.e., upstream and downstream) homology arms, which relates to the relative position of the homology arms in the polynucleotide construct. The 5' and 3' homology arms hybridize to regions within the target locus where the construct is integrated, which are referred to herein as the "5' target sequence" and "3' target sequence," respectively. [0605] The homology arm must be sufficiently complementary for hybridization to the target sequence to mediate homologous recombination between the construct and genomic DNA at the target locus. For example, a homology arm may comprise a nucleotide sequence having at least about 80-100% sequence identity to the corresponding genomic target sequence, including any percent identity within this range, such as at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% sequence identity thereto, wherein construct is integrated into the genomic DNA by HDR at the genomic target locus recognized (i.e., sufficiently complementary for hybridization) by the 5' and 3' homology arms. [0606] In certain embodiments, the corresponding homologous nucleotide sequences in the genomic target sequence (i.e., the "5' target sequence" and "3' target sequence") flank a specific site for cleavage and/or a specific site for integrating the construct. The distance between the specific cleavage site and the homologous nucleotide sequences (e.g., each homology arm) can be several hundred nucleotides. In some embodiments, the distance between a homology arm and the cleavage site is 200 nucleotides or less (e.g., 0, 10, 20, 30, 50, 75, 100, 125, 150, 175, and 200 nucleotides). In most cases, a smaller distance may give rise to a higher gene targeting rate. [0607] A homology arm can be of any length, e.g., 10 nucleotides or more, 50 nucleotides or more, 100 nucleotides or more, 250 nucleotides or more, 300 nucleotides or more, 350 nucleotides or more, 400 nucleotides or more, 450 nucleotides or more, 500 nucleotides or more, 1000 nucleotides (1 kb) or more, 5000 nucleotides (5 kb) or more, 10000 nucleotides (10 kb) or more, etc. In some instances, the 5' and 3' homology arms are substantially equal in length to one another, e.g., one may be 30% shorter or less than the other homology arm, 20% shorter or less than the other homology arm, 10% shorter or less than the other homology arm, 5% shorter or less than the other homology arm, 2% shorter or less than the other homology arm, or only a few nucleotides less than the other homology arm. In other instances, the 5' and 3' homology arms are substantially different in length from one another, e.g., one may be 40% shorter or more, 50% shorter or more, sometimes 60% shorter or more, 70% shorter or more, 80% shorter or more, 90% shorter or more, or 95% shorter or more than the other homology arm. [0608] An RNA-guided nuclease can be targeted to a particular genomic sequence (i.e., genomic target sequence for insertion of a polynucleotide construct) by altering its guide RNA sequence. A target-specific guide RNA comprises a nucleotide sequence that is complementary to a genomic target sequence, and thereby mediates binding of the nuclease-gRNA complex by hybridization at the target site. For example, the gRNA can be designed to selectively bind to the chromosomal target site where integration of the construct is desired. In certain embodiments, the RNA-guided nuclease used for genome modification is a clustered regularly interspersed short palindromic repeats (CRISPR) system Cas nuclease. Any RNA-guided Cas nuclease capable of catalyzing site-directed cleavage of DNA to allow integration of polynucleotide constructs by the HDR mechanism can be used for selective integration at a target chromosomal site, including CRISPR system type I, type II, or type III Cas nucleases. Examples of Cas proteins include Cas1, Cas1B, Cas2, Cas3, Cas4, Cas5, Cas5e (CasD), Cas6, Cas6e, Cas6f, Cas7, Cas8a1, Cas8a2, Cas8b, Cas8c, Cas9 (Csn1 or Csx12), Cas10, Cas10d, CasF, CasG, CasH, Csy1, Csy2, Csy3, Cse1 (CasA), Cse2 (CasB), Cse3 (CasE), Cse4 (CasC), Csc1, Csc2, Csa5, Csn2, Csm2, Csm3, Csm4, Csm5, Csm6, Cmr1, Cmr3, Cmr4, Cmr5, Cmr6, Csb1, Csb2, Csb3, Csx17, Csx14, Csx10, Csx16, CsaX, Csx3, Csx1, Csx15, Csf1, Csf2, Csf3, Csf4, and Cu1966, and homologs or modified versions thereof. [0609] In certain embodiments, a type II CRISPR system Cas9 endonuclease is used. In some embodiments, Cas9 nucleases from any species, or biologically active fragments, variants, analogs, or derivatives thereof that retain Cas9 endonuclease activity (i.e., catalyze site-directed cleavage of DNA to generate double-strand breaks) may be used to selectively integrate a construct at a chromosomal target site as described herein. In certain embodiments, the Cas9 need not be physically derived from an organism but may be synthetically or recombinantly produced. Cas9 sequences from a number of bacterial species are well known in the art and listed in the National Center for Biotechnology Information (NCBI) database. See, for example, NCBI entries for Cas9 from: Streptococcus pyogenes (WP_002989955, WP_038434062, WP_011528583); Campylobacter jejuni (WP_022552435, YP_002344900), Campylobacter coli (WP_060786116); Campylobacter fetus (WP_059434633); Corynebacterium ulcerans (NC_015683, NC_017317); Corynebacterium diphtheria (NC_016782, NC_016786); Enterococcus faecalis (WP_033919308); Spiroplasma syrphidicola (NC_021284); Prevotella intermedia (NC_017861); Spiroplasma taiwanense (NC_021846); Streptococcus iniae (NC_021314); Belliella baltica (NC_018010); Psychroflexus torquisI (NC_018721); Streptococcus thermophilus (YP_820832), Streptococcus mutans (WP_061046374, WP_024786433); Listeria innocua (NP_472073); Listeria monocytogenes (WP_061665472); Legionella pneumophila (WP_062726656); Staphylococcus aureus (WP_001573634); Francisella tularensis (WP_032729892, WP_014548420), Enterococcus faecalis (WP_033919308); Lactobacillus rhamnosus (WP_048482595, WP_032965177); and Neisseria meningitidis (WP_061704949, YP_002342100); all of which sequences (as entered by the date of filing of this application) are herein incorporated by reference. Any of these sequences or a variant thereof comprising a sequence having at least about 70-100% sequence identity thereto, including any percent identity within this range, such as 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, or 99% sequence identity thereto, can be used for genome editing, as described herein.

[0610] In some embodiments, the CRISPR-Cas system naturally occurs in bacteria and archaea where it plays a role in RNA-mediated adaptive immunity against foreign DNA. In certain embodiments, the bacterial type II CRISPR system uses the endonuclease, Cas9, which forms a complex with a guide RNA (gRNA) that specifically hybridizes to a complementary genomic target sequence, where the Cas9 endonuclease catalyzes cleavage to produce a double-stranded break. In certain embodiments, targeting of Cas9 typically further relies on the presence of a 5′ protospacer-adjacent motif (PAM) in the DNA at or near the gRNA-binding site. [0611] In some embodiments, the genomic target site may comprise a nucleotide sequence that is complementary to the gRNA and may further comprise a protospacer adjacent motif (PAM). In certain embodiments, the target site comprises 20-30 base pairs in addition to a 3 base pair PAM. Typically, the first nucleotide of a PAM can be any nucleotide, while the two other nucleotides will depend on the specific Cas9 protein that is chosen. Exemplary PAM sequences are known to those of skill in the art and include, without limitation, NNG, NGN, NAG, and NGG, wherein N represents any nucleotide. In certain embodiments, the allele targeted by a gRNA comprises a mutation that creates a PAM within the allele, wherein the PAM promotes binding of the Cas9-gRNA complex to the allele. [0612] In certain embodiments, the gRNA is 5-50 nucleotides, 10-30 nucleotides, 15-25 nucleotides, 18-22 nucleotides, or 19-21 nucleotides in length, or any length between the stated ranges, including, for example, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, or 35 nucleotides in length. In some embodiments, the guide RNA may be a single guide RNA comprising crRNA and tracrRNA sequences in a single RNA molecule, or the guide RNA may comprise two RNA molecules with crRNA and tracrRNA sequences residing in separate RNA molecules. [0613] In another embodiment, the CRISPR nuclease from Prevotella and Francisella 1 (Cpf1) may be used. In some embodiments, Cpf1 is another class II CRISPR/Cas system RNA-guided nuclease with similarities to Cas9 and may be used analogously. Unlike Cas9, Cpf1 does not require a tracrRNA and only depends on a crRNA in its guide RNA, which provides the advantage that shorter guide RNAs can be used with Cpf1 for targeting than Cas9. Cpf1 is capable of cleaving either DNA or RNA. The PAM sites recognized by Cpf1 have the sequences 5'-YTN-3' (where "Y" is a pyrimidine and "N" is any nucleobase) or 5'-TTN-3', in contrast to the G-rich PAM site recognized by Cas9. Cpf1 cleavage of DNA produces double- stranded breaks with a sticky-ends having a 4 or 5 nucleotide overhang. For a discussion of Cpf1, see, e.g., Ledford et al. (2015) Nature.526 (7571):17-17, Zetsche et al. (2015) Cell.163 (3):759-771, Murovec et al. (2017) Plant Biotechnol. J.15(8):917-926, Zhang et al. (2017) Front. Plant Sci.8:177, Fernandes et al. (2016) Postepy Biochem.62(3):315-326; herein incorporated by reference. [0614] In some embodiments, C2c1is another class II CRISPR/Cas system RNA-guided nuclease that may be used. C2c1, similarly to Cas9, depends on both a crRNA and tracrRNA for guidance to target sites. For a description of C2c1, see, e.g., Shmakov et al. (2015) Mol Cell. 60(3):385-397, Zhang et al. (2017) Front Plant Sci.8:177; herein incorporated by reference. [0001] In yet another embodiment, an engineered RNA-guided FokI nuclease may be used. In some embodiments, RNA-guided FokI nucleases comprise fusions of inactive Cas9 (dCas9) and the FokI endonuclease (FokI-dCas9), wherein the dCas9 portion confers guide RNA-dependent targeting on FokI. For a description of engineered RNA-guided FokI nucleases, see, e.g., Havlicek et al. (2017) Mol. Ther.25(2):342-355, Pan et al. (2016) Sci Rep.6:35794, Tsai et al. (2014) Nat Biotechnol.32(6):569-576; herein incorporated by reference. [0615] In some embodiments, the RNA-guided nuclease can be provided in the form of a protein, such as the nuclease complexed with a gRNA, or provided by a nucleic acid encoding the RNA-guided nuclease, such as an RNA (e.g., messenger RNA) or DNA (expression vector) that is introduced into the host cell. In certain embodiments, Codon usage may be optimized to improve production of an RNA-guided nuclease in a particular cell or organism. For example, a nucleic acid encoding an RNA-guided nuclease can be modified to substitute codons having a higher frequency of usage in a yeast cell, a bacterial cell, a human cell, a non-human cell, a mammalian cell, a rodent cell, a mouse cell, a rat cell, or any other host cell of interest, as compared to the naturally occurring polynucleotide sequence. When a nucleic acid encoding the RNA-guided nuclease is introduced into cells, the protein can be transiently, conditionally, or constitutively expressed in the cell. [0616] In some embodiments, a polynucleotide construct is site-specifically integrated into the genome of a host cell using a clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 system, wherein the construct is integrated into a Cas9-induced double-strand break at the target chromosomal site. In some embodiments, a vector encoding Cas9 and a gRNA targeting the desired chromosomal site for integration is introduced into the host cell. In some embodiments, sequences with homology to the target locus are introduced into the polynucleotide construct to allow for integration by homology-directed repair. For a description of the use of a CRISPR-Cas9 systems for targeted genomic integration of AAV constructs, see, e.g., Nat. Commun. (2019) 10(1):4439; herein incorporated by reference. [0617] Alternatively, site-specific recombinases can be used to selectively integrate a polynucleotide construct at a target chromosomal site. In some embodiments, a target chromosomal site for integration of one or more polynucleotide constructs disclosed herein may include transcriptionally active chromosomal sites. Examples of transcriptionally active chromosomal sites include DNaseI hypersensitive sites (DHSs). In some embodiments, a polynucleotide construct can be site-specifically integrated into the genome of a host cell by introducing a first recombination site into the construct and expressing a site-specific recombinase in the host cell. In some embodiments, the target chromosomal site of the host cell comprises a second recombination site, wherein recombination between the first and second recombination sites mediated by the site-specific recombinase results in integration of the vector at the target chromosomal locus. In some embodiments, the target chromosomal site may comprise either a recombination site native to the genome of the host cell or an engineered recombination site recognized by the site-specific recombinase. In some embodiments, various recombinases may be used for site-specific integration of vector constructs, including, but not limited to phi C31 phage recombinase, TP901-1 phage recombinase, and R4 phage recombinase. In some cases, a recombinase engineered to improve the efficiency of genomic integration at the target chromosomal site may be used. For a description of various site-specific recombinase systems and their use in site-specific recombination and genomic integration of constructs, see, e.g., U.S. Patent No.6,632,672; Olivares et al. (2001) Gene 278:167-176; Stoll et al. (2002) J. Bacteriol.184(13):3657-3663; Thyagarajan et al. (2001) Mol. Cell Biol.21(12):3926-3934; Sclimenti et al. (2001) Nucleic Acids Res.29(24):5044-5051; Stark et al. (2011) Biochem. Soc. Trans.39(2):617-22; Olorunniji et al. (2016) Biochem. J.473(6):673-684; Birling et al. (2009) Methods Mol.

[0618] In some embodiments, one or more of the polynucleotide constructs are not integrated into the genome of the production host cell, and instead are maintained in the cell extrachromosomally. Examples of extrachromosomal polynucleotide constructs include those that persist as stable/persistent plasmids or episomal plasmids. In some embodiments, a construct comprises Epstein-Barr virus (EBV) sequences, including the EBV origin of replication. oriP, and the EBV gene, EBNA1, to provide stable extrachromosomal maintenance and replication of the construct. For a description of methods of using EBV sequences to stably maintain vectors extrachromosomally, see, e.g., Stoll et al. (2010) Mol. Ther.4(2):122-129 and Deutsch et al. (2010) J. Virol.84(5):2533-2546; herein incorporated by reference in their entireties. In some embodiments, the polynucleotide constructs of the present disclosure may be introduced into a cell in manner similar to the currently used triple-transfection method for production of rAAV virions. [0619] In a preferred embodiment, this system requires only one antibiotic resistance marker, and two split auxotrophic constructs for selection of all three plasmids, each being transformed just once into the DHFR knockout strain- producing a master cell line for virion production which can be stored and then utilized for scaled-up production without further transformations. This approach provides inducible control over expression of the Rep/Cap products avoiding the toxicity typically associated with Rep/Cap production and also avoids selection with multiple antibiotics, which is not preferred for therapeutic products. In some embodiments, both overexpression of Rep/Cap and selection with multiple antibiotics can be toxic and result in diminished virion yield. In other embodiments, the transformed cells can be frozen for storage and thawed for subsequent applications. 1.8.

[0732] In some embodiments, a) a first polynucleotide construct comprises the first polynucleotide and the second polynucleotide; optionally, wherein the first polynucleotide construct has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to SEQ ID NO: 32.

[0734] In other embodiments, cells for inducibly producing AAV comprise a) a first polynucleotide construct comprising the first polynucleotide and the second polynucleotide; optionally, wherein the first polynucleotide construct has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to SEQ ID NO: 32; b) a second polynucleotide construct comprising the third polynucleotide, optionally, wherein the second polynucleotide construct has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to SEQ ID NO: 149; c) a third polynucleotide construct comprising the fourth, optionally, wherein the third polynucleotide construct has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to SEQ ID NO: 30; and d) a fourth polynucleotide construct comprising the fifth polynucleotide, optionally, wherein the fourth polynucleotide construct has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% sequence identity to SEQ ID NO: 147. [0735] In some embodiments, the first polynucleotide construct, second polynucleotide construct, and the third polynucleotide construct are integrated into the nuclear genome of the cell, and wherein the AAV Rep proteins, the AAV Cap proteins, and the one or more adenoviral helper proteins are conditionally expressible and when the cell expresses the AAV Rep, the Cap proteins, and the helper proteins, the cell conditionally produces recombinant AAV (rAAV) virions. [0736] In some embodiments, the first polynucleotide construct, second polynucleotide construct, the third polynucleotide construct and fourth polynucleotide construct are integrated into the nuclear genome of the cell, and wherein the AAV Rep proteins, the AAV Cap proteins, and the one or more adenoviral helper proteins are conditionally expressible and when the cell expresses the AAV Rep, the Cap proteins, and the helper proteins, the cell conditionally produces recombinant AAV (rAAV) virions. [0737] In some embodiments, the first polynucleotide construct, second polynucleotide construct, the third polynucleotide construct, fourth polynucleotide construct and fifth polynucleotide construct are integrated into the nuclear genome of the cell, and wherein the AAV Rep proteins, the AAV Cap proteins, and the one or more adenoviral helper proteins are conditionally expressible and when the cell expresses the AAV Rep, the Cap proteins, and the helper proteins, the cell conditionally produces recombinant AAV (rAAV) virions. [0738] In some embodiments, cells of interest comprise a plurality of the first polynucleotide construct, the second polynucleotide construct, the third polynucleotide construct, the fourth polynucleotide construct, or the fifth polynucleotide construct, or any combination thereof. [0739] In some embodiments, the first polynucleotide construct further comprises a first constitutive promoter operably linked to a sequence encoding a first selectable marker. [0740] In some embodiments, the third polynucleotide construct comprises a sequence encoding the activator. In certain embodiments, the sequence encoding the activator is operably linked to a constitutive promoter. In certain embodiments, the constitutive promoter is EF1alpha promoter or human cytomegalovirus promoter. [0741] In some embodiments, the activator is reverse tetracycline-controlled transactivator (rTA) comprising a Tet Repressor binding protein (TetR) fused to a VP16 transactivation domain. [0742] In some embodiments, the triggering agent for inducing the tetracycline-inducible promoter is tetracycline or doxycycline. [0743] In some embodiments, the inducible recombinase is fused to an estrogen response element (ER) and translocates to the nucleus in the presence of tamoxifen. [0744] In some embodiments, the recombination sites in the first polynucleotide construct and the third polynucleotide construct are lox sites and the recombinase is a cre recombinase or wherein the recombination sites in the first polynucleotide construct and the third polynucleotide are flippase recognition target (FRT) sites and the recombinase is a flippase (Flp) recombinase. [0745] In some embodiments, presence of the triggering agent activates the activator for activation of the first inducible promoter to express Cap proteins from the third polynucleotide comprising the third sequence encoding the AAV Cap proteins. [0746] In some embodiments, presence of the triggering agent activates the activator for activation of the second inducible promoter to express the Rep proteins, the Cap proteins of the second polynucleotide, the inducible recombinase, and the one or more AAV helper proteins. [0747] In some aspects, the cells or stable cells may further include a fourth polynucleotide construct encoding a payload. [0748] In some embodiments, these cells provide for an increased levels of AAV capsid proteins thereby leading to increased rAAV production as compared to cells that include the first and third polynucleotide construct but do not include a second polynucleotide construct comprising a third sequence encoding the AAV Cap proteins. [0749] In some embodiments, the third polynucleotide construct permits inducible expression of a hormone-activated excising element. In some embodiments, the excising element can be a recombinase. In some embodiments, the recombinase can be a site-specific recombinase. In some embodiments, the site-specific recombinase can be a Cre polypeptide or a flippase. Triggering of Cre expression via an inducible promoter leads to recombination at lax sites, which in turn lead to expression of adenovirus helper proteins, expression of AAV Rep and Cap proteins, and production of rAAV, optionally, encapsidating a therapeutic payload (e.g., transgene, a tRNA suppressor, a guide RNA, or other oligonucleotide). [0750] In certain embodiments, expression of the Cre recombinase and the AAV capsid proteins from the second polynucleotide construct may be under the control of the same inducible promoter. Such a configuration may lead to a substantially simultaneous expression of AAV capsid proteins from the first polynucleotide construct (where the expression is activated after the action of Cre) and from the second polynucleotide construct. [0751] While the figures provided herein show specific arrangement of genes in the polynucleotide constructs, any combination that is capable of conditionally producing AAV Rep/Cap proteins and producing rAAV is also envisioned. [0752] FIG.1A depicts an exemplary system of polynucleotides for inducibly producing rAAV. In the embodiment shown, four synthetic polynucleotide constructs are separately integrated into the nuclear genome of a cell line that expresses adenovirus E1A and E1B, such as HEK 293 cells. In the pre-triggered state “off state” shown in FIG.1A, transcriptional read-through of rep on Construct 1 is blocked by an excisable element comprising a first recombination site, a coding sequence comprising a stop signaling sequence, a second recombination site. A first and second recombination sites flank the coding sequence comprising a stop signaling sequence and the first recombination site and the second recombination site are oriented in the same direction. Construct 1 comprises from 5’ to 3’: one or more promoters operably linked to a sequence comprising a first part of an AAV Rep coding sequence, a 5’ splice site, a first part of an intron, a first recombination site, a first 3’ splice site, a coding sequence comprising a stop signaling sequence, a second recombination site, a second part of the intron, a second 3’ splice site, and a sequence comprising a second part of the AAV Rep coding sequence, wherein the first recombination site, the first 3’ splice site, the coding sequence comprising the stop signaling sequence, and the second recombination site form an excisable element, wherein the first recombination site and the second recombination site are oriented in the same direction, and wherein the one or more promoters are not operably linked to the sequence comprising the second part of the AAV Rep coding sequence. [0753] Construct 2 encodes a mammalian selectable marker under the control of a constitutive promoter and AAV capsid proteins under the control of an inducible promoter. Each of Constructs 1 and 2 include sequences that encode for the same Cap proteins. In some embodiments, each of the Constructs 1 and 2 encodes for AAV5 cap proteins, VP1, VP2, and VP3. [0754] In some embodiments, Construct 3 includes a conditionally self-excising element which permits conditional expression of ER2 Cre under the control of an inducible promoter. For example, the inducible promoter is a Tet-inducible promoter (e.g., Tet-On promoter). In certain embodiments, in the absence of a triggering agent, the inducible promoter is not active. For example, a triggering agent for Tet-inducible promoter is a tetracycline. In certain embodiments, in the absence of a tetracycline, such as doxycycline (“Dox”), Tet activator protein (TetOn3G) expressed, under the control of a constitutive promoter, cannot bind and activate the basal Tet inducible promoter. In other embodiments, in addition, the localization of Cre is under control of estrogen response elements (“ER2”) that require binding of an estrogen agonist or selective modulator, such as tamoxifen, for the translocation from the cytoplasm to the nucleus. This approach limits pre-triggering Cre expression with consequent promiscuous recombination events and toxicity. In some embodiments, the ER2 Cre element also comprises a strong 3’ polyadenylation signal, which prevents basal expression of the downstream adenoviral helper genes, E2A and E4. [0755] In some embodiments, the Cre element is split into two fragments, that can be fused in the presence of a chemical agent, such as rapamycin. In some embodiments, the Cre is a light inducible Cre. [0756] In some embodiments, the Construct 3 comprises a P2A sequence positioned between an E2A sequence and an E4 sequence. The P2A sequence encodes a self-cleaving peptide such that E2A and E4 proteins are generated after cleavage of a fusion protein comprising E4, P2A, E2A amino acid sequences. In some embodiments, the Construct 3 comprises an internal ribosomal entry site (IRES) sequence positioned between an E2A sequence and an E4 sequence. In some embodiments, an IRES can comprise at least 80%, 85%, 90%, 95%, 98%, 99% or 100% sequence identity to SEQ ID NO: 135. [0757] In some embodiments, the inducible promoter system of Construct 3 is a tetracycline- inducible promoter (e.g., a Tet On inducible promoter that is part of a Tet On inducible promoter system). In some embodiments, the inducible promoter system of Construct 3 is a Tet Off inducible promoter system. In some embodiments, the inducible promoter system of Construct 3 is a cumate inducible promoter system. [0758] In this embodiment, in Construct 3, the activator TetOn3G is expressed under the control of the constitutive EF1alpha promoter and a gene encoding for puromycin resistance is under the control of the constitutive CMV promoter. In some embodiments, Construct 3 includes an optional insert which includes a Cre inducible U6 promoter that drives the expression of transcriptionally dead mutants of VA RNA1 (VA RNA). Specifically, the U6 promoter is split into two parts separated by a Lox flanked stuffer sequence. The U6 promoter is inactive because of the presence of the stuffer sequence. Cre mediated excision of the stuffer sequence activates the U6 promoter, which then drives the expression of VA RNA. [0759] In some embodiments, the payload polynucleotide on Construct 4 is flanked by AAV ITRs, represented by the brackets. In other embodiments, Construct 4 also includes a constitutive promoter operably linked to a sequence encoding a selectable marker or a first portion or a second portion of a split selectable marker. In the embodiment depicted in FIG.1A, Construct 1 includes a sequence encoding a first portion or a second portion of a split selectable marker and Construct 4 includes a sequence encoding the other portion of the split selectable marker. [0760] In some embodiments, when a first triggering agent (e.g., doxycycline, which is also referred to as Dox) and a second triggering agent (e.g., tamoxifen) are added to the culture medium, Tet-on 3G and Dox bind the Tet responsive basal promoter and ER2 Cre is expressed and translocates to the nucleus. In some embodiments, ER2 Cre excises its own coding sequence from Construct 3, leaving the integrated construct shown in FIG.1B. Excision of the self-excising ER2 Cre coding sequence allows expression of E2A and E4 helper proteins under the control of the tetracycline-inducible promoter. Similarly, for the optional additional insert shown in FIG.1A, VA-RNA is expressed following Cre mediated excision of the stuffer sequence, which activates the U6 promoter which then drives the expression of VA-RNA, as shown in FIG.1B. [0761] In some embodiments, Construct 1 is designed to prevent expression of AAV Rep prior expression and translocation of ER2 Cre and permit expression of AAV Rep and Cap proteins from their endogenous promoters after translocation of ER2 Cre to the nucleus. [0762] In the embodiment shown in FIG.1A, the excisable element in Construct 1 which interrupts the rep coding sequence, blocking transcriptional read-through of the full-length rep coding sequence results in production of a pre-triggered transcript that includes the 5’ portion of AAV Rep coding sequence fused to a blue fluorescent marker protein (BFP) coding sequence. In some embodiments, the transcript contains a single intron flanked by 5’ and 3’ splice sites. Routine splicing produces a transcript that encodes a fusion protein that includes the N-terminal portion of rep fused to BFP. The fusion protein lacks the toxicity of full-length Rep protein, and presence of pre-triggered Construct 1 in the cell genome can be detected by BFP fluorescence for quality control. [0763] In some embodiments, the excisable element comprises a first spacer segment, a second spacer segment, and a third spacer segment. In some embodiments, the excisable element is inserted at an insertion site between the p19 internal promoter and the p40 internal promoter of the AAV Rep coding sequence. In some embodiments, the insertion site is CAG-G, CAG-A, AAG-G, or AAG-A, wherein the dash (-) indicates the point of insertion of the excisable spacer. In other embodiments, Construct 1 also includes a sequence encoding a selectable marker. In certain embodiments, the selectable marker may be a split selectable marker, e.g., split antibiotic resistance protein expressed under the control of a constitutive promoter. [0764] FIG.1B shows the conversion of the pre-triggered Construct 1 to a post-triggered state “on state” upon exposure to ER2 Cre within the cell nucleus. ER2 Cre excises the excisable element, which includes the BFP marker coding sequence and the upstream 3’ splice site. As rearranged, the construct now allows expression of functional Rep and Cap transcripts from their respective endogenous promoters. Loss of BFP expression indicates successful Cre-mediated genomic recombination. [0765] An exemplary embodiment of Construct 4 shown in FIG.1A and FIG.1B encodes a payload. In some embodiments, Construct 4 includes a polynucleotide encoding a payload, which can be a gene of interest flanked by ITRs, and a second portion of the selectable marker expressed from a constitutive promoter. In some embodiments, the polynucleotide payload can be any payload for which rAAV is an appropriate vehicle, including a transgene encoding a protein of interest, a homology element for homology-directed repair, or a guide RNA. In other embodiments, the polynucleotide payload is flanked by AAV ITRs, represented by the brackets. In certain embodiments, the sequence encoding the payload may be under control of a constitutive promoter. In certain embodiments, the sequence encoding the payload is under control of a tissue-specific promoter active in the tissue where the payload is to be delivered. [0766] FIG.1B depicts the post-triggered state “on state” of the constructs shown in FIG.1A following the addition of tamoxifen and doxycycline to the cell medium. Adenoviral E2A and E4 helper proteins are expressed from integrated Construct 3 under control of the inducible promoter (e.g., a Tet-On promoter activated in the presence of Dox). AAV rep and cap coding sequences are expressed from Construct 1 under control of endogenous promoters. In some embodiments, AAV cap coding sequences are expressed from Construct 2 under control of the Tet promoter. rAAV virions that encapsidate the payload are therefore produced. [0767] This approach provides numerous benefits over current AAV systems for delivery of payloads. [0768] In some embodiments, maintaining constructs stably in the cellular genome requires selective pressure. FIGS.1A and 1B depict polynucleotides for selection of cells based in antibiotics resistance. In this example, the split blasticidin is used in Constructs 1 and 4. A separate exemplary antibiotic selection approach, puromycin resistance, is used in Construct 3. A separate exemplary antibiotic selection approach, hygromycin resistance, is used in Construct 2. This results in the ability to stably maintain all four constructs in the mammalian cell line using three antibiotics. [0769] In some embodiments, to reduce the number of selective agents (and in particular, antibiotics) required to stably maintain integrated constructs within the cell line genome, other approaches that stably maintains all 4 constructs in the nuclear genome with two antibiotic selections, plus a single auxotrophic selection can also be utilized. In some embodiments, the cell line stably maintains all 4 constructs in the nuclear genome with no antibiotic selection and instead utilizes auxotrophic protein selection. [0770] In certain embodiments, a split auxotrophic selection system that permits stable retention of two integrated nucleic acid constructs under a single selective pressure can be used. One construct encodes the N-terminal fragment of mammalian dihydrofolate reductase (DHFR) fused to a leucine zipper peptide (“Nter-DHFR”). This N-terminal fragment is enzymatically nonfunctional. The other construct encodes the C-terminal fragment of DHFR fused to a leucine zipper peptide (“Cter-DHFR”). This C-terminal fragment is enzymatically nonfunctional. When both fragments are concurrently expressed in the cell, a functional DHFR enzyme complex is formed through association of the leucine zipper peptides. Both constructs can be stably retained in the genome of a DHFR null cell by growth in a medium lacking hypoxanthine and thymidine. [0771] An exemplary deployment of this split auxotrophic selection design in the multi- construct system of FIG.1A is disclosed. In this example, the split auxotrophic selection elements are deployed on Constructs 1 and 4. A separate exemplary antibiotic selection approach, puromycin resistance, is deployed on Construct 3. A separate exemplary antibiotic selection approach, hygromycin resistance, is deployed on Construct 2. This results in the ability to stably maintain all four constructs in the mammalian cell line using two antibiotics, culturing in medium with puromycin and hygromycin, lacking thymidine and hypoxanthine. [0772] In some embodiments, the split selection system is a split intervening proteins (inteins) system that permits stable retention of two integrated nucleic acid constructs under a single selective pressure. Inteins auto catalyze a protein splicing reaction that results in excision of the intein and joining of the flanking amino acids (extein sequences) via a peptide bond. Inteins exist in nature as a single domain within a host protein or, less frequently, in a split form. For split inteins, the two separate polypeptide fragments of the intein must associate in order for protein trans-splicing to occur to excise the intein. Split intein systems are described in: Cheriyan et al, J. Biol. Chem 288: 6202-6211 (2013); Stevens et al, PNAS 114: 8538-8543 (2017); Jillette et al., Nat Comm 10: 4968 (2019); US 2020/0087388 A1; and US 2020/0263197 A1. In some embodiments, the split auxotrophic selection system described herein comprises a construct encoding an N-terminal fragment of an auxotrophic protein fused to an N-terminal intein of the split intein and a construct encoding the C-terminal fragment of the auxotrophic protein fused to a C-terminal intein of the split intein. In certain embodiments, this N-terminal fragment is enzymatically nonfunctional and this C-terminal fragment is enzymatically nonfunctional. When both fragments are concurrently expressed in the cell, the split inteins can catalyze the joining of the N-terminal fragment of the auxotrophic protein and a C-terminal fragment of the auxotrophic protein to form a functional enzyme, such as any one of the enzymes disclosed herein (e.g., PAH, GS, TYMS, DHFR). In some embodiments, both constructs can be stably retained in the genome of a cell by growth in a medium lacking the product produced by the enzyme. In some embodiments, the split auxotrophic selection elements (e.g., a construct encoding an N-terminal fragment of an auxotrophic protein fused to an N- terminal intein of the split intein and a construct encoding the C-terminal fragment of the auxotrophic protein fused to a C-terminal intein of the split intein) deployed on, for example, Constructs 1 and 4, are part of a split intein system. A separate exemplary auxotrophic selection approach, e.g., a full length auxotrophic protein, can be deployed on Construct 3. In some embodiments, a construct encoding an N-terminal fragment of an auxotrophic protein fused to an N-terminal intein of the split intein or a construct encoding the C-terminal fragment of the auxotrophic protein fused to a C-terminal intein of the split intein further encodes a helper enzyme, wherein expression of the helper enzyme facilitates growth of the host cell in conjunction with the functional enzyme upon application of the single selective pressure. [0773] In some embodiments, following triggering and Cre-mediated genomic rearrangement, the selection elements remain unchanged, allowing continued maintenance of the four post- triggering integrated constructs using two antibiotics in medium lacking hypoxanthine and thymidine. [0774] In some embodiments, viral proteins needed for AAV virion formation are inhibited by host cell mechanisms. Inhibition of these host cell mechanisms to maximize AAV viral titers in the stable cell lines described herein include, but are not limited to: knocking out PKR (PKR KO) (pathway is responsible for inhibition of viral proteins) in the starting cell line (P0), introducing a mutant EIF2alpha (in the PKR pathway) in the starting cell line (P0), and/or manipulating or modulating virus-associated (VA) RNAs (VA-RNAs, an inhibitor of PKR). Virus-associated (VA) RNAs from adenovirus act as small-interference RNAs and are transcribed from the vector genome. These VA-RNAs can trigger the innate immune response. Moreover, VA-RNAs are processed to functional viral miRNAs and disturb the expression of numerous cellular genes. Therefore, VA-deleted adenoviral vector production constructs (AdVs) lacking VA-RNA genes, or having modified VA-RNA, would be advantageous. However, VA- deleted AdVs do not produce commercially sufficient quantities of AAV titers (e.g., resulting in fewer and poor-quality virions). Conversely, overexpressing VA-RNA also results in a low titer of AAV production that would not be commercially feasible for scale-up. Thus, developing conditional VA-RNA constructs, and combining any of those optimized constructs with the conditional helper constructs described herein, will provide commercially relevant, high-quality virions from the AAV production systems as described herein. All three of these strategies can be done in any combination. [0775] In some embodiments, VA-RNA is also an inhibitor of PKR, which is involved in a pathway responsible for inhibiting AAV viral protein synthesis. In particular, PKR phosphorylates EIF2alpha, which results in inhibition of viral protein synthesis. [0776] While the limited interactions between VA-RNA, PKR, and EIF2alpha are understood, PKR is a major kinase that may self-phosphorylate and EIF2alpha may be phosphorylated by other kinases. As such, three strategies (PKR KO, EIF2alpha mutation, manipulation of VA- RNA) are being developed for use in any combination in the AAV production systems described herein. [0777] In some aspects, the constructs of this system can also be used in a vector system, wherein the constructs do not integrate into the genome of the cell. [0778] In the embodiment shown in FIG.2A, an exemplary system of polynucleotides for inducibly producing rAAV is depicted. In absence of a first triggering agent and a second triggering agent, the system is in an off state. In Construct 1, depicted in this embodiment, the sequence encoding the AAV Cap proteins is operably linked to an inducible promoter. The coding sequences and promoters for the Rep proteins are separated from the coding sequence and inducible promoter for the Cap proteins by a transcription blocking element (TBE). The coding sequence for the Rep proteins is similar to the coding sequence for the Rep proteins described in FIG.1A. This construct may also be referred to as a Rep-Cap construct. This construct comprises from 5’ to 3’: one or more promoters operably linked to a sequence comprising a first part of an AAV Rep coding sequence, a 5’ splice site, a first part of an intron, a first recombination site, a first 3’ splice site, a coding sequence comprising a stop signaling sequence, a second recombination site, a second part of the intron, a second 3’ splice site, and a sequence comprising a second part of the AAV Rep coding sequence, wherein the first recombination site, the first 3’ splice site, the coding sequence comprising the stop signaling sequence, and the second recombination site form an excisable element, wherein the first recombination site and the second recombination site are oriented in the same direction, and wherein the one or more promoters are not operably linked to the sequence comprising the second part of the AAV Rep coding sequence. Construct 2 is similar to Construct 4 depicted in FIGS.1A and 1B. Construct 3 is similar to Construct 3 depicted in FIGS.1A and 1B.

Conditional expression [0813] In a first aspect, stable cell lines, e.g., mammalian stable cell lines, capable of conditionally producing recombinant AAV (rAAV) virions are provided. The rAAV virions package an expressible payload, such as, a sequence encoding a therapeutic nucleic acid or protein or a complex therefore. In certain embodiments, production of virions is not conditioned on the presence of an episome or independent plasmid within the cell. [0814] In another aspect, the plasmids are provided comprising the constructs as disclosed herein. In some embodiments, the plasmids further comprise Epstein-Barr virus (EBV) sequences to stably maintain the constructs extrachromosomally. Rep Protein and Cap Protein Inducible Expression [0815] As discussed herein, expression of AAV Rep and Cap proteins is conditional. In certain embodiments, expression of AAV Cap proteins is conditioned on addition of at least a first triggering agent to the cell culture medium. In certain embodiments, expression of AAV Rep proteins is conditioned on addition of a first triggering agent and a second triggering agent to the cell culture medium. [0816] In some embodiments, the first triggering agent is . In certain embodiments, doxycycline is used to the control a Tet inducible promoter. In certain embodiments, the expression of the AAV cap proteins is under the control of a Tet inducible promoter. [0817] In some embodiments, expression of AAV Rep proteins is conditional. In certain embodiments, expression of AAV Rep proteins is conditioned on addition of at least a first triggering agent to the cell culture medium. In certain embodiments, expression of AAV Rep proteins is conditioned on addition of a first triggering agent and a second triggering agent to the cell culture medium. In certain embodiments, a first triggering agent is used to the control a Tet inducible promoter. In certain embodiments, the expression of the AAV cap proteins is under the control of a Tet inducible promoter. In some embodiments, a first triggering agent is doxycycline. [0818] In some embodiments, alternatively, other inducible promoters can be utilized instead of a Tet inducible promoter, such as, but not limited to, a cumate inducible promoter system, which is under the control of cumate as the triggering agent or an ecdysone-inducible promoter, which is under the control of ecdysone or ponasterone as the triggering agent. Site-Specific Recombinase System [0819] In some embodiments, any suitable inducible excising agent (e.g., recombinase) can be utilized. In certain embodiments, an excising agent can be a recombinase. In certain cases, an excising agent can be a site-specific recombinase. Exemplary site-specific recombinase systems include, without limitation, Cre-loxP, Flp-FRT, PhiC31-att, Dre-rox, and Tre-loxLTR site- specific recombinase systems. In some embodiments, the Cre-loxP system uses a Cre recombinase to catalyze site-specific recombination between two loxP sites. In some embodiments, the Flp-FRT system uses a flippase (FLP) recombinase to catalyze site-specific recombination between two flippase recognition target (FRT) sites. In some embodiments, the PhiC31-att system uses a phiC31 recombinase to catalyze site-specific recombination between two attachment (att) sites referred to as attB and attP. In some embodiments, the Dre-rox system uses a DreO recombinase to catalyze site-specific recombination between two rox sites. In some embodiments, the Tre-loxLTR system uses a Tre recombinase to catalyze site-specific recombination between two loxP sites that are modified with HIV long terminal repeats (loxLTR). For a description of various site-specific recombinase systems, see, e.g., Stark et al. (2011) Biochem. Soc. Trans.39(2):617-22; Olorunniji et al. (2016) Biochem. J.473(6):673-684; Birling et al. (2009) Methods Mol. Biol.561:245-63; García-Otin et al. (2006) Front. Biosci. 11:1108-1136; Weasner et al. (2017) Methods Mol. Biol.1642:195-209; herein incorporated by reference in their entireties. [0820] In some embodiments, an excising agent can target a recombination site. Examples of suitable inducible excising agents include Cre and a flippase. In certain embodiments, the Cre element can be hormone activated Cre, or light inducible Cre. In some embodiments, a recombination site can be a lox site. In certain embodiments, a lox site can be a loxP site. In other embodiments, a recombination site can be an FRT site. [0821] In some embodiments, the Flippase recombinase system is based on Flp-FRT recombination, a site-directed recombination technology used to manipulate DNA under controlled conditions in vivo. It is analogous to Cre-lox recombination but involves the recombination of sequences between short flippase recognition target (FRT) sites by the recombinase flippase (Flp) derived from the 2 µ plasmid of baker's yeast Saccharomyces cerevisiae. The Flp protein, much like Cre, is a tyrosine family site-specific recombinase. [0822] In typical embodiments, the cells do not express cytotoxic levels of Rep protein prior to addition of both the first expression and second triggering agents to the cell culture medium. In certain embodiments, the cells do not express cytostatic levels of Rep protein prior to addition of both the first and second triggering agents to the cell culture medium. In certain embodiments, the average concentration of Rep protein within the cells is less than the amount prior to addition of both of the first and second triggering agents to the cell culture medium. In some embodiments, expression of Rep and Cap proteins becomes constitutive after addition of all of the at least first triggering agents to the cell culture medium. [0823] In some embodiments, expression of at least one adenoviral helper protein is conditional. In certain embodiments, expression of the at least one adenoviral helper protein is conditioned on addition of at least a third triggering agent to the cell culture medium. In particular embodiments, the third triggering agent is the same as the first triggering agent. In certain embodiments, expression of adenoviral helper proteins is conditioned on addition of a third triggering agent and a fourth triggering agent to the cell culture medium. In particular embodiments, the fourth triggering agent is the same as the second triggering agent. In particular embodiments, the third triggering agent is the same as the first triggering agent and the fourth triggering agent is the same as the second triggering agent. For example, the first triggering agent and the third triggering agent are both doxycycline. For example, the second triggering agent and the fourth triggering agent are both tamoxifen. [0824] In some embodiments, continued expression of adenoviral helper proteins following triggering of expression by contact of the cell with the at least third triggering agent requires the presence of only the third triggering agent in the cell culture medium. In certain embodiments, the third triggering agent is the same as the first triggering agent. For example, the first triggering agent and the third triggering agent are both doxycycline. [0825] In some embodiments, expression of at least one adenoviral helper RNA is conditional. In certain embodiments, the adenoviral helper proteins comprise Ad E2A. In certain embodiments, the adenoviral helper proteins comprise Ad E4. In some embodiments, the adenoviral helper protein is tagged. A tag can be a protein tag. A protein tag can be a FLAG tag. In some embodiments, E2A is FLAG-tagged. In some embodiments, E4 is FLAG-tagged. [0826] In particular embodiments, the adenoviral helper RNA is a VA-RNA. In particular embodiments, the adenoviral helper RNA is expressed from an inducible VA-RNA construct. In some embodiments, the VA-RNA is a mutant VA-RNA. In some embodiments, the VA-RNA is a transcriptionally dead VA-RNA. In some embodiments, the VA-RNA is under the control of an RNA polymerase III promoter. In some embodiments, the VA-RNA is under the control of an interrupted RNA polymerase III promoter. In some embodiments, the VA-RNA is under the control of a U6 or U7 promoter. In some embodiments, the VA-RNA is under the control of an interrupted U6 or U7 promoter. [0827] In some embodiments, the third triggering agent is a tetracycline. In certain embodiments, the tetracycline is doxycycline (“Dox”). In some embodiments, the fourth triggering agent is an estrogen receptor ligand. In certain embodiments, the estrogen receptor ligand is a selective estrogen receptor modulator (SERM). In particular embodiments, the estrogen receptor ligand is tamoxifen. [0828] In some embodiments of the stable cell line, expression of the payload is conditioned on addition of at least a fifth triggering agent to the cell culture medium. In some embodiments, expression of the payload is not conditioned on addition of an triggering agent to the cell culture medium. [0829] In some embodiments, expression of Rep and Cap proteins, Cap proteins, adenoviral helper proteins, and the payload becomes constitutive after addition of only one triggering agent to the cell culture medium. In certain embodiments, expression of Rep and Cap proteins, Cap proteins, and the adenoviral helper proteins becomes constitutive after addition of only one triggering agent to the cell culture medium. [0830] In certain embodiments, the one triggering agent is the first triggering agent. In certain embodiments, the first triggering agent is a tetracycline. In particular embodiments, the first triggering agent is doxycycline. 1.11.

In some embodiments, the first therapeutically effective amount and the second therapeutically effective amount vary by no more than 1%, 5%, 10%, or 15%. Methods of Delivering a Payload or Protein [0935] Once formulated, compositions comprising an rAAV virion or protein (e.g., therapeutic protein such as an antibody or any fragment or derivative thereof) may be administered directly to a subject or, alternatively, delivered ex vivo, to cells derived from the subject. For example, methods for the ex vivo delivery and reimplantation of transformed cells into a subject are known in the art and may include, e.g., dextran-mediated transfection, calcium phosphate precipitation, polybrene mediated transfection, lipofectamine and LT-1 mediated transfection, protoplast fusion, electroporation, encapsulation of the polynucleotide(s) in liposomes, and direct microinjection of the DNA into nuclei. Direct delivery of a vector system comprising an expressible sequence encoding a payload of interest in vivo will generally be accomplished by injection using either a conventional syringe, needless devices such as Bioject or a gene gun, such as the Accell gene delivery system (PowderMed Ltd, Oxford, England). [0936] In certain embodiments, rAAV of the present disclosure or compositions comprising the rAAV may be administered to a subject in need thereof by any suitable route, such as, intravenous, intramuscular, intracranial, intracerebroventicular, intrathecal, intracisternal, or via brain surgery. [0937] In some embodiments, the rAAV virions comprising an expressible sequence encoding a payload of interest are used in gene therapy applications to treat a disease. The payload may be, for example, a polypeptide, a protein, or an RNA. A polypeptide or a protein may be, for example, an enzyme, an antibody, a hormone, an aptamer, or an endonuclease (e.g., a site- specific endonuclease such an RNA-guided endonuclease), a component of a CRISPR/Cas system, an adenosine deaminase acting on RNA (ADAR) enzyme, a transcriptional activator, a transcriptional repressor, or any combination thereof, as described above. The payload may be progranulin. An RNA may be, for example, a guide RNA, a tRNA, a suppressor tRNA, a siRNA, a miRNA, an mRNA, a shRNA, a circular RNA, an antisense oligonucleotide (ASO), a ribozyme, a DNAzyme, an aptamer, or any combination thereof. In some embodiments, the rAAV virions used in gene therapy applications to treat a disease comprise one or more expressible sequences encoding one or more payloads of interest. For example, the rAAV virions comprise two expressible sequences, wherein a first expressible sequence encodes for a first gRNA and a second expressible sequence encodes for a second gRNA. In some embodiments, the first gRNA and the second gRNA are different. In some embodiments, the first gRNA and the second gRNA are the same. [0938] In some embodiments, the protein (e.g., therapeutic protein such as an antibody or any fragment or derivative thereof) is used in gene therapy applications to treat a disease. The protein may be, for example, a polypeptide. A polypeptide or a protein may be, for example, an enzyme, an antibody, a hormone, an aptamer, or an endonuclease (e.g., a site-specific endonuclease such an RNA-guided endonuclease), a component of a CRISPR/Cas system, an adenosine deaminase acting on RNA (ADAR) enzyme, a transcriptional activator, a transcriptional repressor, or any combination thereof, as described above. [0939] The rAAV virions or protein (e.g., therapeutic protein) may be formulated into compositions for delivery to a vertebrate subject (e.g., mammalian subject, preferably human). These compositions may either be prophylactic (to prevent a disease or condition) or therapeutic (to treat a disease or condition). The compositions will comprise a “therapeutically effective amount” of the rAAV virions such that amounts of the payload of interest may be produced in vivo sufficient to have a therapeutic benefit in the individual to which it is administered. The compositions will comprise a “therapeutically effective amount” of the protein (e.g., therapeutic protein) such that amounts have a therapeutic benefit in the individual to which it is administered. The exact amounts necessary will vary depending on the subject being treated; the age and general condition of the subject to be treated; the degree of protection desired; the severity of the condition being treated; the particular therapeutic agent produced, and the mode of administration, among other factors. An appropriate effective amount may be readily determined by one of skill in the art. Thus, a “therapeutically effective amount” will fall in a relatively broad range that may be determined through routine trials. [0940] A “therapeutically effective amount” of virion comprising an expressible sequence encoding a payload of interest will fall in a relatively broad range that may be determined through experimentation and/or clinical trials. For example, for in vivo injection, a therapeutically effective dose of rAAV virions will be on the order of from about 106 to about 1015 of the rAAV virions, e.g., from about 108 to 1012 rAAV virions. For in vitro transduction, an effective amount of rAAV virions to be delivered to cells will be on the order of from about 108 to about 1013 of the rAAV virions. Other effective dosages may be readily established by one of ordinary skill in the art through routine trials establishing dose response curves. [0941] In some cases, more than one administration (e.g., two, three, four or more administrations) may be employed to achieve the desired level of gene expression. In some cases, more than one administration is administered at various intervals, e.g., daily, weekly, twice monthly, monthly, every 3 months, every 6 months, yearly, etc. In some cases, multiple administrations are administered over a period of time from 1 month to 2 months, from 2 months to 4 months, from 4 months to 8 months, from 8 months to 12 months, from 1 year to 2 years, from 2 years to 5 years, or more than 5 years. 1.15. rAAV Virion Produced by Methods of the Present Disclosure [0942] In some aspects, the rAAV virion produced by the methods described in section “1.14.

EXAMPLES [0949] Below are examples of specific embodiments for carrying out the present invention. The examples are offered for illustrative purposes only, and are not intended to limit the scope of the present invention in any way. Efforts have been made to ensure accuracy with respect to numbers used (e.g., amounts, temperatures, etc.), but some experimental error and deviation should, of course, be allowed for. [0950] The practice of the present invention will employ, unless otherwise indicated, conventional methods of protein chemistry, biochemistry, recombinant DNA techniques and pharmacology, within the skill of the art. Such techniques are explained fully in the literature. Example 1 - Mammalian cell line with three stably integrated plasmids [0951] A stable mammalian cell line v1.0 capable of inducible expression of rAAV encapsidating a payload was constructed by integrating three nucleic acid constructs (e.g., see FIG.16) via plasmids into the nuclear genome of a cell line that expresses adenovirus E1A and E1B. The plasmids were a plasmid having the sequence of SEQ ID NO: 30, a plasmid having the sequence of SEQ ID NO: 32, and either a plasmid having the sequence of SEQ ID NO: 33 or a plasmid having the sequence of SEQ ID NO: 147. Cells that successfully integrated all three v1.0 constructs are selected and maintained by growth in media in the presence of puromycin and blasticidin. See FIG.4. SCC refers to single cell clones. Example 2 – Mammalian cell line with four stably integrated plasmids [0952] v1.0 cells that successfully integrated all three v1.0 constructs are transfected with a plasmid encoding AAV5 capsid proteins under control of an inducible promoter and resistance to hygromycin and selected for hygromycin resistance to produce v1.2 cells, referred to as T231 (P3) or T231 in subsequent figures. The plasmid encoding AAV5 capsid proteins under control of an inducible promoter and resistance to hygromycin had a sequence of SEQ ID NO: 149. Control cells were produced by transfecting v1.0 cells with a stuffer control plasmid, referred to as T232 (P3) or T232 in subsequent figures. The plasmid stuffer control plasmid had a sequence of SEQ ID NO: 150. See FIG.5. [0953] FIG.6 provides data for the titer of AAV Capsid proteins and the titer of AAV Capsids proteins encapsidating the gene encoding progranulin (PGRN) produced in T231 (P3) and T232 (P3) cells. The table shows percent packaging of the gene encoding PGRN. The T231 (P3) cells or the T232 (P3) cells are pooled cells (also referred to as T231 stable cell pool or T232 stable cell pool), in which a pool comprises more than one single cell clone that can later be isolated and expanded to produce a monoclonal cell population. [0954] FIG.7 depicts v1.2 system that in addition to the polynucleotides of the v1.0 system (Contruct 1, Construct 3, and Construct 4) includes an additional polynucleotide (Construct 2) for encoding AAV Cap proteins to achieve an overall increase in AAV Cap proteins expression as compared to the v1.0 system. The payload (“GOI”) of polynucleotide (Construct 4) may encode for either progranulin or GFP. [0955] FIG.8 provides an overview schematic summarizing induction of cells that include the v1.2 system of polynucleotide constructs “v1.2 cells” and characterization of the Capsid levels, excision kinetics for production of AAV Rep and Cap, GOI levels, and levels of encapsidated GOI. [0956] FIG.9 provides a timeline from the point of induction of cells when tamoxifen and doxycycline are added (T=0) through 96 hours post-induction (T=96 hours). Expression of a protein marker, blue fluorescent protein, encoded by Construct 1 of FIG.7 prior to the induction in v1.2 cells (pooled) was measured and compared to the an expanded single cell clone that has only integrated the helper construct (T177CL9; see FIG.4 schematic). Presence of the additional Construct 2 of FIG.7 was shown to not impact excision of the gene encoding BFP such that AAV Rep and Cap proteins were expressed. [0957] FIG.10 provides data for characterization of rAAV produced by v1.2 cells (wherein the encapsidated payload is progranulin and the induced cells are pooled cells) and v1.0 cells (wherein the encapsidated payload is progranulin and the induced cells are pooled cells) (left two graphs). [0958] Encapsidated gene of interest (GOI) was measured using droplet digital PCR (ddPCR). Crude lysate was treated with Benzonase to remove unencapsidated DNA. Benzonase was then inactivated and viral particles are denatured to expose encapsidated GOI. This DNA was quantified by ddPCR using GOI specific primer and probe set. Capsids levels were measured by ELISA. [0959] Total gene of interest was measured using ddPCR. Viral particles in crude cell lysate are denatured to expose encapsidated GOI. Both unencapsidated and encapsidated DNA are quantified by ddPCR using GOI specific primer and probe set. [0960] Capsids titer was measured by ELISA. [0961] FIG.11 shows a timeline for production of viral particles over a 7 day period after induction of v1.2 cells (wherein the encapsidated payload is progranulin and the induced cells are pooled cells) and v1.0 cells (wherein the encapsidated payload is GFP and the induced cells are from an expanded single cell clone) with tamoxifen and doxycycline. In FIG.11, expression of total capsid production was measured. Capsids levels were measured by ELISA. [0962] FIG.12 shows a timeline for production of viral particles over a 7-day period after induction of v1.2 cells (wherein the encapsidated payload is progranulin and the induced cells are pooled cells) and v1.0 cells (wherein the encapsidated payload is GFP and the induced cells are from an expanded single cell clone) with tamoxifen and doxycycline. In FIG.12, expression of capsid encapsidated vector genomes (encapsidated payload) was measured. [0963] FIG.13 shows high titer produced after induction of v1.2 cells from the T231 stable cell pool wherein the payload is progranulin (“v1.2 Pool (PGRN)”). This v1.2 Pool (PGRN) titer is higher than the titer produced via transient transfection wherein the payload is eGFP (Transient Transfection (eGFP)), titer produced by a v1.0 stable cell pool wherein the payload is progranulin (v1.0 Pool (PGRN)), and titer produce by a v1.0 stable cell pool wherein the payload is eGFP (v1.0 Pool (eGFP)), indicating the v1.2 stable cell pool may comprise single cell clones, that when isolated and expanded to monoclonal populations, may be capable of producing higher titer than titer produced by single cell clones from v1.0 stable cell pools isolated and expanded to monoclonal populations, and higher titer than titer produced by transient transfection. [0964] FIG.14A shows high capsid titer produced after induction of v1.2 pool cells wherein the payload is progranulin (v1.2 Pool (PGRN)) and after induction of v1.2 single cell clones wherein the payload is progranulin (v1.2 Clones (PGRN)). The v1.2 Pool (PGRN) capsid titer and v1.2 Clones (PGRN) capsid titer are higher than the v1.0 stable pool cells wherein the payload is eGFP (v1.0 eGFP Pool) capsid titer, v1.0 single stable cell clones wherein the payload is eGFP (v1.0 eGFP clones) capsid titer, v1.0 stable pool cells wherein the payload is progranulin (v1.0 PGRN Pool) capsid titer, and v1.0 single stable cell clones wherein the payload is progranulin (v1.0 PGRN Clones)capsid titer, indicating the v1.2 stable cells have successfully increased capsid titer >2 log. [0965] FIG.14B shows high vector genome production after induction of v1.2 pool cells wherein the payload is progranulin (v1.2 Pool (PGRN)) and after induction of v1.2 single cell clones wherein the payload is progranulin (v1.2 Clones (PGRN)). The v1.2 Pool (PGRN) vector genome titer and v1.2 Clones (PGRN) vector genome titer are higher than the v1.0 stable pool cells wherein the payload is eGFP (v1.0 eGFP Pool) vector genome titer, v1.0 single stable cell clones wherein the payload iseGFP (v1.0 eGFP clones) vector genome titer, v1.0 stable pool cells wherein the payload is progranulin (v1.0 PGRN Pool) vector genome titer, and v1.0 single stable cell clones wherein the payload is progranulin (v1.0 PGRN Clones) vector genome titer, indicating the v1.2 stable cells have successfully increased vector genome titer. [0966] FIG.15 shows high encapsidated vector genome (vg) production and high capsid (vp) titer produced after induction of a v1.2 pooled cell line (T318). T318 was generated from T205 CL23 clone. T205 CL23 clone was the top clone selected on the basis of highest vg/ml and vp/ml production from pool of T205 cells that have stably integrated Construct 1, Construct 3, and Construct 4 (see FIG.7). T318 cells were generated by then introducing Construct 2 into T205 CL23 clone and selecting for cells resistant to puromycin, blasticidin, and hygromycin.

Example 4 - Rep Cap construct Integration Into a Stable Cell Line [0968] This example describes integration of a construct 1 encoding Rep and Cap polypeptides (SEQ ID NO: 7) into a stable cell line and describes inducible expression of Rep and Cap polypeptides in said stable cell line. An AAV2 genome without the ITRs and with the polynucleotide construct was cloned into a piggybac vector with a Blasticidin resistance gene (SEQ ID NO: 8). The excisable element interrupting Rep was inserted downstream of the p19 promoter, as shown in FIG.1A. [0969] Suspension HEK293 cells (viral production cells, VPCs; also referred to as the parental cells or parental VPC pool) were transfected using a PEI pro transfection reagent. The ratio of transposon to transposase ratio used was 2:1. Cells were allowed to recover in non-selective media for 72 hours and passaged into selective media (10 µg/ml Blasticidin). Example 5 - Inducible Helper Constructs [0970] This example describes inducible helper constructs of the present disclosure. A tetracycline/ doxycycline (“Dox”) inducible promoter (TRE3G) drives the expression of estrogen inducible cre (ER2 cre). The estrogen inducible cre has a strong polyadenylation signal (stop signal) at its 3’ end. The cre gene and the polyadenylation signal are flanked by lox sites. Following this is a bicistronic E2A E4, orf6 cassette. The plasmid also has a constitutive promoter (mutant EF1alpha), which drives the expression of Tet-on 3G (Tet responsive activator protein). [0971] Mechanism of action: In the off state (in the absence of Dox), Tet-on 3G is unable to bind the Tet operator elements in the TRE3G promoter and, thus, the TRE3G promoter is not active. In an embodiment of the system, an estrogen responsive Cre is used instead of simple Cre to counteract any basal (or “leaky”) expression of the TRE3G promoter. Thus, even if the system yields leaky expression of the Cre gene, the expressed Cre protein will be held inactive in the cytoplasm. The strong polyadenylation stop signal positioned 3’ of the Cre gene will prevent basal expression of adenoviral helper genes (E2A and E4). [0972] To induce expression, Dox and Tamoxifen are added to the cell culture. Dox binds to the Tet-on 3G protein and promotes binding of Tet-on 3G to the Tet operator elements in the TRE3G promoter. This triggers activation of the promoter. ER2 Cre is expressed at high levels and Tamoxifen brings Cre to the nucleus. Cre recombines the lox sites, causing excision of the Cre-polyadenylation cassette. This brings the bicistronic E2A and E4 cassette next to the tetracycline-inducible promoter triggering their expression. Self-excision of Cre will limit the duration of Cre expression in the cells thus limiting Cre related toxicity and promiscuous recombination events. [0973] A first version of an inducible helper construct (STXC0123) is shown in FIG.1A. The construct also has a mutant of VA-RNA (G16A and G60A, which disable the internal PolIII promoter) driven by a U6 promoter. The proximal sequence element (PSE) and distal sequence element (DSE) of the U6 promoter are separated by a Lox sequence-flanked stuffer sequence (PGK driven Fusion Red-PuroR), thus, disabling the promoter. The promoter is reconstituted by Cre mediated excision of the stuffer sequence, resulting in VA-RNA expression conditional upon Cre expression. The inducible helper construct can have a sequence of SEQ ID NO: 153. The inducible helper construct can be in a plasmid having a sequence of SEQ ID NO: 30 or SEQ ID NO: 154. [0974] A second version of an inducible helper construct (STXC0133) can include a constitutively expressed VA-RNA element driven by its internal native promoters. The inducible helper construct can be in a plasmid having a sequence of SEQ ID NO: 31. [0975] Multiple variations of the inducible helper construct are envisioned. Fusion Red-PuroR can be replaced with PuromycinR and the PGK promoter can be replaced with a CMV promoter in two different orientations. [0976] The Rep Cap construct can be a STXC0137 plasmid (SEQ ID NO: 32) and payload construct can be a STXC0136 plasmid (SEQ ID NO: 33). The payload construct (STXC0136) comprises a sequence that encodes GFP flanked by ITRs (STX650 (sc GFP AAV) (SEQ ID NO: 34)) and the other half of a split blasticidin resistance gene, both under control of a constitutive promoter. Example 6 – Stable Cell Line for Production of Virions Encapsidating a Sequence Coding for Progranulin [0977] A stable mammalian cell line (“Progranulin Stable Cell line”) capable of inducible expression of rAAV encapsidating a sequence coding for progranulin is constructed by integrating three nucleic acid constructs (STXC-0123 (SEQ ID NO: 30), STXC0137 (SEQ ID NO: 32), and STXC0136 (SEQ ID NO: 33), in which the GFP of STXC0136 is replaced with a sequence coding for progranulin (e.g., SEQ ID NO: 147, SEQ ID NO: 157, or SEQ ID NO: 159)) into the nuclear genome of a cell line that expresses adenovirus E1A and E1B. Cells that successfully integrated all 3 constructs are selected and maintained by growth in media in the presence of puromyocin and blasticidin to produce a stable cell line. [0978] The stable cell line is cultured, and then a construct similar to construct 2 (e.g., SEQ ID NO: 149) is transfected into the stable cell line. After selection, the v1.2 stable cell line is therefore producede and these v1.2 stable cells are induced to produce rAAV by adding Dox and Tamoxifen to the Progranulin Stable Cell line. Example 7 – AAV production in GS KO cells that integrated a helper construct comprising a GS selectable marker, a Rep Cap construct comprising a C-term of a split Blasticidin resistance protein selectable marker, a payload construct comprising a N-term of a split Blasticidin resistance protein selectable marker, and a Cap construct [0979] Glutamine Synthetase KO cells were transfected with a vector system comprising the helper construct comprising Glutamine Synthetase as a selectable marker, a Rep Cap construct comprising a C-term of a split Blasticidin resistance protein as a selectable marker, a payload construct comprising a N-term of a split Blasticidin resistance protein as a selectable marker, and a Cap construct with a third selectable marker. Example 8 – Exemplary V1.2 System [0980] This example describes another V1.2 system in which Cap proteins are expressed under the control of an inducible promoter that is stronger than native AAV p40 promoter. See, for example, Construct 1 of FIG.2A. The Rep proteins coding sequence is oriented in a direction opposite to the Cap proteins coding sequence. A TBE is positioned between the two sequences. The Cap proteins coding sequence includes a SV40 polyA signal sequence such that the SV40 polyA signal sequence is 3’ to the Cap coding sequence. [0981] In one method for generating cells with the V1.2 system, Construct 3 as shown in FIG. 2A is introduced in the cells and cells resistant to puromycin are selected. Constructs 1 and 2 as shown in FIG.2A are introduced into cells resistant to puromycin and cells resistant to puromycin and blasticidin are selected to generate cells harboring all three constructs. [0982] In another method, Constructs 1 and 2 as shown in FIG.2A are introduced into cells and cells resistant to blasticidin are selected. Construct 3 as shown in FIG.2A is introduced in the cells resistant to blasticidin and cells resistant to puromycin and blasticidin are selected to generate cells harboring all three constructs. [0983] Cells harboring all three constructs are separated into single cells which are expanded to generate clonal cell lines. Alternatively, a pool of cells harboring all three constructs are expanded. [0984] Clonal cell lines or pooled cells harboring all three constructs are induced by addition of doxycycline and tamoxifen. Addition of doxycycline results in expression of Cap proteins and ER2 Cre. In the presence of tamoxifen, ER2 Cre translocates to the nucleus and excises the excisable element positioned between the first part and the second part of the Rep coding sequence, resulting in expression of Rep. After induction, the Construct 3 of FIG.2A having a sequence of SEQ ID NO: 153 is induced to a Construct 3 of FIG.2B having a sequence of SEQ ID NO: 155. After induction, the Rep construct of Construct 1 of FIG.2A having a sequence of SEQ ID NO: 160 is induced to a Rep construct of Construct 1 of FIG.2B having a sequence of SEQ ID NO: 161. After induction, the Construct 1 of FIG.2A having a sequence of SEQ ID NO: 164 is induced to a Construct 1 of FIG.2B having a sequence of SEQ ID NO: 165. After induction, the VA-RNA construct of Construct 3 of FIG.2A having a sequence of SEQ ID NO: 167 is induced to a VA-RNA construct of Construct 3 of FIG.2B having a sequence of SEQ ID NO: 168. Since Cap is expressed under the control of Tet-On promoter which is stronger than the AAV p40 promoter used for expressing Cap proteins in the V1.0 system, these cells lines will produce higher levels of Cap proteins and higher levels of rAAV as compared to V1.0 system. Example 9 – AAV Cap encoding sequence comprising bGH or RBG poly A signal sequence [0985] This example describes the V1.2 system described in Example 8. The Cap proteins are expressed under the control of Tet-On promoter. The Cap proteins coding sequence includes a bGH or RBG poly A signal sequence located 3’ to the Cap proteins coding sequence. [0986] In one method for generating cells with the V1.2 system, Construct 3 as shown in FIG. 2A is introduced in the cells and cells resistant to puromycin are selected. Constructs 1 and 2 as shown in FIG.2A are introduced into cells resistant to puromycin and cells resistant to puromycin and blasticidin are selected to generate cells harboring all three constructs. [0987] In another method, Constructs 1 and 2 as shown in FIG.2A are introduced into cells and cells resistant to blasticidin are selected. Construct 3 as shown in FIG.2A is introduced in the cells resistant to blasticidin and cells resistant to puromycin and blasticidin are selected to generate cells harboring all three constructs. [0988] Cells harboring all three constructs are separated into single cells which are expanded to generate clonal cell lines. Alternatively, a pool of cells harboring all three constructs are expanded. [0989] Clonal cell lines or pooled cells harboring all three constructs are induced by addition of doxycycline and tamoxifen. Addition of doxycycline results in expression of Cap proteins and ER2 Cre. In the presence of tamoxifen, ER2 Cre translocates to the nucleus and excises the excisable element positioned between the first part and the second part of the Rep coding sequence, resulting in expression of Rep. Since Cap is expressed under the control of Tet-On promoter which is stronger than the AAV p40 promoter used for expressing Cap proteins in the V1.0 system, these cells lines will produce higher levels of Cap proteins and higher levels of rAAV as compared to V1.0 system. Example 10 – Exemplary V1.2 System [0990] This example describes another V1.2 system which includes two separate nucleic acids for inducibly expressing Cap proteins. Such a system is depicted in FIGS.3A and 3B. In this V1.2 system, Cap proteins are expressed under the control of Tet-On promoter. The constructs shown in FIG.3A may be introduced into cells in any suitable order. Cells harboring all four constructs are selected by growing the transduced cells in the presence of puromycin, blasticidin and hygromycin. The Cap proteins coding sequence present on the same polynucleotide as the Rep coding sequence may include a native polyA signal sequence and the Cap proteins coding sequence present on the separate polynucleotide may include a SV40 polyA signal sequence positioned 3’ to the Cap proteins coding sequence. [0991] Addition of doxycycline results in production of Cap proteins. Addition of doxycycline and tamoxifen results in production of rAAV. As compared to the V1.0 system which has a high level of unencapsidated payload, the increased level of Capsid proteins is expected to increase the levels of rAAV as observed in Fig.10 when using the V1.2 system depicted in FIG.1. Example 11 – Exemplary V1.2 System [0992] This example describes another V1.2 system which includes two separate nucleic acids for inducibly expressing Cap proteins. Such a system is depicted in FIGS.3A and 3B. In this V1.2 system, Cap proteins are expressed under the control of Tet-On promoter. The constructs shown in FIG.3A may be introduced into cells in any suitable order. Cells harboring all four constructs are selected by growing the transduced cells in the presence of puromycin, blasticidin and hygromycin. The Cap proteins coding sequence present on the same polynucleotide as the Rep coding sequence may include a native polyA signal sequence and the Cap proteins coding sequence present on the separate polynucleotide may include a bGH or RBG polyA signal sequence positioned 3’ to the Cap proteins coding sequence. Addition of doxycycline results in production of Cap proteins. Addition of doxycycline and tamoxifen results in production of rAAV. As compared to the V1.0 system which has a high level of unencapsidated payload, the increased level of Capsid proteins is expected to increase the levels of rAAV as observed in Fig. 10 when using the V1.2 system depicted in FIG.1. Example 12 – Viral production in cells selected to comprise a high construct copy number using an attenuated promoter [0993] This example describes viral production in cells that are selected to comprise a high copy number of a construct integrated into a cell using an attenuated promoter. [0994] A plasmid encoding helper proteins and a puromycin resistance gene (helper construct, e.g., a polynucleotide construct comprising SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 30, or SEQ ID NO: 153) is produced. [0995] A glutamine synthetase (GS) protein is split at a Cys residue within the GS protein, in which an attenuated promoter operably linked to a C-Term GS/C-Term intein (referred to as the split-GS C-term module) is integrated into a construct encoding Rep (Rep2) and Cap (Cap5) proteins (e.g., SEQ ID NO: 164) to produce the C-term GS Rep/Cap plasmid, and an attenuated promoter operably linked to an N-Term intein/N-Term GS (referred to as the split-GS N-term module) is integrated into a construct encoding a GFP AAV (e.g., SEQ ID NO: 139) to produce the N-term GS payload plasmid. C-term GS Rep/Cap plasmids and N-term GS payload plasmids comprising the split-GS C-term module or the split-GS N-term module are generated, in which the GS split is at Cys53, Cys183, Cys229, or Cys252. The attenuated promoter is an attenuated EF1alpha promoter having a sequence of SEQ ID NO: 132. [0996] VPCs knocked out for GS are transfected with the helper construct and grown in media having puromycin. Surviving cells containing the helper construct are further transfected (independently for each GS split pair) with C-term GS Rep/Cap plasmids and N-term GS payload plasmids, and then are cultured in media deficient in glutamine to select for cells comprising high copy number integration of C-term GS Rep Cap constructs and N-term GS payload constructs, are expanded, and the copy number integration of C-term GS Rep Cap constructs and N-term GS payload constructs are assessed. The cells are then transfected with a construct encoding an AAV cap protein and another selectable marker. The selected cells are then induced with doxycycline and tamoxifen to produce virions. Titer is measured by qPCR. Example 13 – Viral production in cells selected to comprise a high construct copy number using a selectable marker having weak activity [0997] This example describes viral production in cells that are selected to comprise a high copy number of a construct integrated into a cell using a selectable marker having weak activity, such as a selectable marker mutated to have decreased activity. [0998] A plasmid encoding helper proteins and a puromycin resistance gene (helper construct, e.g., a polynucleotide construct comprising SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 30, or SEQ ID NO: 153) is produced. [0999] A glutamine synthetase (GS) protein is split at a Cys residue within the GS protein, in which a promoter operably linked to a C-Term GS/C-Term intein (referred to as the split-GS C- term module) is integrated into a construct encoding Rep (Rep2) and Cap (Cap5) proteins (e.g., SEQ ID NO: 164) to produce the C-term GS Rep/Cap plasmid and a promoter operably linked to an N-Term intein/N-Term GS (referred to as the split-GS N-term module) is integrated into a construct encoding a GFP AAV (e.g., SEQ ID NO: 139) to produce the N-term GS GOI plasmid. C-term GS Rep/Cap plasmids and N-term GS GOI plasmids comprising the split-GS C-term module or the split-GS N-term module are generated, in which the GS split is at Cys53, Cys183, Cys229, or Cys252, and wherein the GS is a mutated GS having a R324C, R324S, or R341C mutation as compared to SEQ ID NO: 112. The promoter is an EF1alpha promoter having a sequence of SEQ ID NO: 132. [1000] VPCs knocked out for GS are transfected with the helper construct and grown in media having puromycin. Surviving cells containing the helper construct are further transfected (independently for each GS split pair) with C-term GS Rep/Cap plasmids and N-term GS payload plasmids, and then are cultured in media deficient in glutamine to select for cells comprising high copy number integration of C-term GS Rep Cap constructs and N-term GS payload constructs, are expanded, and the copy number integration of C-term GS Rep Cap constructs and N-term GS payload constructs are assessed. The cells are then transfected with a construct encoding an AAV cap protein and another selectable marker. The selected cells are then induced with doxycycline and tamoxifen to produce virions.

[1012] A helper plasmid encoding helper proteins and a puromycin resistance gene (helper construct, e.g., a polynucleotide construct comprising SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 30, or SEQ ID NO: 153) is produced.

The cells are then transfected with a construct encoding an AAV cap protein and another selectable marker. The selected cells are then induced with doxycycline and tamoxifen to produce virions. Titer is measured by qPCR. Example 18 – Viral production in cells selected to comprise a high Rep Cap construct copy number [1014] This example describes several metabolic selection schemes for increasing amplification of a construct (by, e.g., increased expression and/or higher DNA copy number), such as a Rep Cap construct that encodes for a metabolic selectable marker and AAV Rep/Cap proteins (e.g., SEQ ID NO: 164) is tested to identify conditions that lead to amplification of the construct when stably integrated into the genome of a cell. Three conditions are tested: promoter mutagenesis, enzymatic inhibition, and mutation of the metabolic marker expressing gene (e.g., an attenuated version of the metabolic marker). The metabolic marker that are tested are glutamine synthetase (GS). For promoter mutagenesis, the TATA box in the EF1alpha promoter is mutated (SEQ ID NO: 132) and operably linked to full length GS (SEQ ID NO: 112). For GS inhibition, methionine sulfoximine (MSX), which is a direct inhibitor of GS activity, is tested at various concentrations with full length GS (SEQ ID NO: 23) driven by an EF1alpha promoter (SEQ ID NO: 133). For mutation of GS, three different mutations in GS are tested: GS R324C (SEQ ID NO: 142), R324S (SEQ ID NO: 143), and R341C (SEQ ID NO: 144). [1015] The host cell is a HEK293 cell lacking GS (GS-knock out “GS-KO”). The first generation of stable cell lines, P1, comprises cells selected for integration of a construct that expresses AAV helper proteins upon induction and the selectable marker, puromycin, after puromycin selection. The P1 cell line is then transfected with a construct that comprises the payload flanked by ITRs and the selectable marker, blasticidin, to produce P2 cell line after selection in blasticidin. P2 cell line is independently transfected with a different construct that express Rep/Cap upon induction and variations of GS to produce P3 cell line after GS selection. For Path 1, the GS is a full-length GS driven by an attenuated EF1alpha promoter (comprising a TATGTA mutation). For Path 2, the GS was GS R324C, GS R324S, or GS R341C. For Path 3, the GS is a full-length GS that is further selected in media comprising different concentrations of MSX for GS inhibition. [1016] A GS-KO P2 cell line is independently transfected with the various Rep/Cap GS constructs. P3 cells are selected in cell culture media lacking glutamine (-Gln) to select for cells expressing a higher level of GS. For Path 3, P3 cells are cultured in media lacking Gln and in the presence of a GS inhibitor, MSX, at various concentrations, to select for cells expressing a higher level of GS. [1017] The cells are then transfected with a construct encoding an AAV cap protein and another selectable marker. The selected cells are then induced with doxycycline and tamoxifen to produce virions. [1018] Exemplary sequences of constructs and plasmids described herein may be as follows.
