Description

BIOSYNTHETIC ENZYMES OF PLANT AMINO ACIDS This application claims the benefit of the U.S. Provisional Application No.60 / 048, 771, registered on June 6, 1997, and the U.S. Provisional Application No. 60 / 049,443, registered on June 12, 1997.

FIELD OF THE INVENTION This invention is in the field of molecular biology of plants. More specifically, this invention relates to nucleic acid fragments that encode enzymes involved in the biosynthesis of amino acids in plants and seeds.

BACKGROUND OF THE INVENTION Many vertebrates, including man, lack the ability to manufacture a certain number of amino acids and therefore require in their diet of these prefabricated amino acids. These are called essential amino acids. Human foods and animal feeds, derived from many grains, are deficient in essential amino acids, such as lysine, the sulfurized amino acids methionine and cysteine, threonine and tryptophan. For example in corn (Zea mays L.) lysine is the most limited amino acid for the dietary requirements of many animals. Soy flour (Glycina max L.) is used as an additive REF .: 31928 for animal foods based on corn mainly as a lysine supplement. In this way, an increase in the lysine content of either corn or soy would reduce or eliminate the need to supplement the feed of grain mixtures with lysine produced via microbial fermentation. In addition, in corn the sulfur amino acids occupy the third place among the most limited amino acids after lysine and tryptophan, for the dietary requirements of many animals. The use of soy flour, which is rich in lysine and tryptophan to supplement corn in animal feed is limited by the low sulfur amino acid content of the legume. Thus, an increase in the content of the sulfur amino acids in both corn and soy would improve the nutritional quality of the mixtures and reduce the need for additional supplementation through the addition of more expensive methionine.

Lysine, threonine, methionine, cysteine and isoleucine are amino acids derived from aspartate. The regulation of the biosynthesis of each member of this family is interconnected (see Figure 1). One approach to increasing the nutritional quality of human foods and animal feeds is to increase production and accumulation of specific free amino acids via genetic engineering of this biosynthetic pathway.

Alteration of enzyme activity in this route could lead to altered levels of lysine, threonine, methionine, cysteine and isoleucine. However, some of the genes that encode enzymes that regulate this route in plants, especially corn, soybeans and wheat, are available.

The organization of the pathway leading to the biosynthesis of lysine, threonine, methionine, cysteine and isoleucine indicates that the overexpression or reduction of expression of genes encoding, inter alia, threonine synthase, dihydrodipicolinate reductase, diaminopimelate epi erasa, threonine deaminase and S-adenosylmethionine synthetase in corn, soy, wheat and other crop plants could be used to alter the levels of these amino acids in human food and animal feed. Accordingly, the availability of nucleic acid sequences encoding all or a portion of these enzymes would facilitate the development of nutritionally enhanced crop plants.

The symbols and the format used for the nucleotide and amino acid sequence comply with the rules described in 37 C.F.R. §1.822.

DETAILED DESCRIPTION OF THE INVENTION In the context of this discovery, a number of terms will be used. As described, an "isolated nucleic acid fragment" is a DNA or RNA polymer having one or double strand; optionally they contain synthetic, unnatural or altered nucleotide bases. An isolated nucleic acid fragment in the form of a DNA polymer may comprise one or more segments of cDNA, genomic or synthetic DNA. As described herein, "contiguity" refers to a collection of overlapping nucleic acid sequences to form a sequence of contiguous nucleotides. For example, several DNA sequences can be compared and aligned to identify the common or overlapping regions. The individual sequences can then be assembled into a single contiguous nucleotide sequence.

As described "substantially similar" refers to fragments of nucleic acids where changes in one or more nucleotide bases result in the substitution of one or more amino acids, but do not affect the functional properties of the protein encoded by the DNA sequence. "Substantially similar" also refers to nucleic acid fragments wherein changes in one or more nucleotide bases do not affect the ability of the nucleic acid fragment to mediate the alteration of gene expression by counter-sense or co-suppression technology "Substantially "similar" also refers to modifications of the nucleic acid fragments of the current invention such as the deletion or insertion of one or more nucleotides that do not substantially affect the functional properties of the resulting transcription vis-à-vis the ability to mediate the alteration. of the genetic expression by the counter-sense, technology of co-suppression or alteration of the functional properties of the resulting protein molecule. It is therefore understood that the invention encompasses more than the specific sequences exemplified.

For example, it is well known in the art that counter-sense suppression and co-suppression of gene expression can be achieved by using fragments of nucleic acid representing less than the entire coding region of a gene, and by nucleic acid fragments. that do not share 100% of the identity with the gene to be deleted. Moreover, alterations in a gene which result in the production of a chemically equivalent amino acid at a given site, but have no effect on the functional properties of the encoded protein, are well known in the art. In this way, a codon for the amino acid alanine, a hydrophobic amino acid, can be replaced by a codon coding for another less hydrophobic residue, such as glycine, or another more hydrophobic residue, such as valine, leucine or isoleucine. Similarly, in changes that result in substitution of a negatively charged residue for another, such as aspartic acid for glutamic acid, or a positively charged residue for another, such as lysine for arginine, one may also expect to produce a functionally equivalent product. Changes in nucleotides that result in the alteration of the N and C terminal portions of the protein molecule should not be expected to alter the activity of the protein. Each one of the proposed modifications is very deep in the routine of art, as is the determination of retention of biological activity of the coded products. Moreover, the skilled artisan recognizes that substantially similar sequences encompassed by this invention are also defined by their ability to hybridize, under stringent conditions (0.1X SSC, 0.1% SDS, 65 ° C), with the sequences exemplified herein. The preferred substantially similar nucleic acid fragments of the present invention are those fragments of nucleic acids whose DNA sequences are 80% identical to the DNA sequence of the nucleic acid fragments reported herein. The most preferred nucleic acid fragments are 90% identical to the identical DNA sequence of the nucleic acid fragments reported herein. The most preferred nucleic acid fragments are 95% identical to the DNA sequence of the nucleic acid fragments reported herein. The Clustal multiple alignment algorithm (Higgins, D.G. and Sharp, P.M 819899 CABIOS 5: 151-153) was used here with a GAP PENALTY of 10 and a GAP LENGTH PENALTY of 10.

A "substantial portion" of an amino acid or nucleotide sequence comprises sufficient of the amino acid sequence of a polypeptide or of the nucleotide sequence of a gene to achieve a putative identification of that polypeptide or gene, either by manual evaluation of the sequence by an expert, or by comparison of automated computer sequences and identification using algorithms such as BLAST (Basic Local Alignment Seach Tool; Altchul, SF, et al., (1993) J.Mol.Biol.215: 403410; see also www.ncbi.nlm.nih.gov/BLAST/). In general, the sequence of ten or more contiguous amino acids or thirty or more nucleotides is necessary in order to putatively identify the polypeptide or nucleic acid sequence as a homolog of a known protein or gene. In addition, with respect to the nucleotide sequences, the specific oligonucleotide gene examined, comprising 20-30 contiguous nucleotides, can be used in methods of genetic identification of dependent chain (eg, Southern hybridization) and isolation (eg, in if your hybridization of bacterial colonies or bacteriophage plaques). In addition, short oligonucleotides of 12-15 bases can be used as amplification primers in PCR in order to obtain a specific fragment of particular nucleic acid comprising primers. Accordingly, a "substantial portion" of a nucleotide sequence comprises sufficient of the sequence to provide specific identification and / or isolation of the nucleic acid fragment comprising the sequence. The current specification teaches the partial or complete sequences of amino acids and nucleotides encoding one or more particular plant proteins. The skilled artisan, having the benefit of the sequences as reported here, may now use all or a substantial portion of the disclosed sequences for purposes known to those skilled in the art. Accordingly, the present invention comprises the complete sequences as reported in the Sequence List, as well as the substantial portions of these sequences as defined above.

"Degenerate codon" refers to divergence in the genetic code allowing variation of the nucleotide sequence without affecting the amino acid sequence of a coded polypeptide. Accordingly, the present invention relates to any nucleic acid fragment that encodes all or a substantial portion of the amino acid sequence encoding biosynthetic amino acid enzymes as set forth in the sequences SEQ ID NOS: 2, 4, 7, 9, 11 , 13, 16, 18, 20, 22, 24, 26, 29, 31 and 33. The skilled artisan is well aware of the "codon-bias" displayed by a specific host cell in use of nucleotide codons to specify a given amino acid. Therefore, when a gene is synthesized to improve expression in the host cell, it is desirable to design such a gene that its frequency of codon usage approaches the frequency of use of preferred codons of the host cell.

"Synthetic genes" can be assembled from blocks constructed of oligonucleotides that are chemically synthesized using methods known to those skilled in the art. These constructed blocks are linked and hardened to form segments of genes that are then enzymatically assembled to build the entire gene. "Chemically synthesized", in relation to the DNA sequence, means that the nucleotide components were assembled in vi tro. Manual chemical synthesis of DNA can be completed using well-established procedures, or automatic chemical synthesis of DNA can be performed using one of a considerable number of commercial machines available. Therefore, genes can be adapted for optimal gene expression based on optimization of the nucleotide sequence to reflect the codon-bias of the host cell. Trained artisans appreciate the likelihood of successful gene expression if the use of the codon is predisposed to those codons favored by the host. The determination of the preferred codons can be based on a study of the genes derived from the host cell where the sequence of information is available.

"Gene" refers to the nucleic acid fragment that expresses a specific protein, including the regulatory sequences preceding (5 'non-coding sequence) and following (3' non-coding sequence) the coding sequence. "Native gene" refers to the gene as it is found in nature with its own regulatory sequences. "Chimeric gene" is. refers to any gene that is not a native gene, comprising regulatory and coding sequences that are not found together in nature. Accordingly, a chimeric gene can comprise regulatory sequences and coding sequences that are derived from different sources, or regulatory sequences and coding sequences derived from the same source, but arranged in a different way from that found in nature. "Endogenous gene" refers to the native gene in its original position in the genome of an organism. "Foreign" gene refers to a gene not normally found in the host organism, but which is introduced into the host organism by gene transfer. Foreign genes may comprise native genes inserted into a non-native organism, or chimeric genes. A "transgene" is a gene that has been introduced into the genome by a transformation procedure.

"Coding sequence" refers to a DNA sequence that codes for a specific amino acid sequence "Regulatory sequences" refers to nucleotide sequences located at the upper end (non-coding sequences), middle, or end lower (3 'non-coding sequences) of a coding sequence, and which influence the transcription, processing or stability of RNA, or translation of an associated coding sequence Regulatory sequences may include promoters, leader translation sequences, introns and polyadenylation sequences recognizing "Promoter" refers to a DNA sequence capable of controlling the expression of an RNA coding or functional sequence. In general, a coding sequence is located 3 'to a promoter sequence. The promoter sequence consists of proximal and more distal elements at the upper end as well as the last elements are referred to as enhancers. Accordingly, an "enhancer" is a DNA sequence which can stimulate promoter activity and can be an innate element of a promoter or a heterologous element inserted to improve the level or tissue specificity of a promoter. The promoters can be derived in their entirety from a native gene, or they can be composed of different elements derived from different promoters found in nature, or they can still comprise synthetic segments of DNA. It is understood by those skilled in the art that different promoters can direct the expression of a gene in different tissues or cell types, or at different stages of development, or in response to different environmental conditions. Promoters which cause a gene to be expressed in most cell types are most often referred to as "constitutive promoters". New promoters of various useful types in plant cells are constantly being discovered; several examples can be found in the compilation of Okamuro and Goldberg, (1989) Biochemistry of Plants 15: 1 -82. It is further recognized that, in most cases, the exact boundaries of the regulatory sequences have not been fully defined, DNA fragments of different lengths may have identical promoter activity.

The "leader translation sequence" refers to a DNA sequence located between the promoter sequence of a gene and the coding sequence. The leader translation sequence is presented at the fully processed upper end of messenger RNA of the initial translation sequence. The leader translation sequence may affect the processing of the primary translation of messenger RNA, the stability of the messenger RNA or the translation efficiency. Examples of leading translation sequences have been described (Turner, R. and Foster, G.D. (1985) Molecular Biotechnology 3: 225).

The "3 'non-coding sequences" refer to DNA sequences located at the lower end of a coding sequence and include polyadenylation recognition sequences and other coding regulatory signal signals capable of affecting mRNA processing or gene expression. The polyadenylation signal is usually characterized in that it affects the addition of polyadenylic acid channels to the 3 'end of the mRNA precursor. The use of different 3 'non-coding sequences is exemplified by Ingelbrecht et. al., (1989) Plant Cell 1: 671-680.

"RNA transcription" refers to the product resulting from transcription catalyzed by an RNA polymerase to a DNA sequence. When the RNA transcript is a perfect complementary copy of a DNA sequence, it is referred to as a primary transcript or it can be an RNA sequence derived from a post-transcriptional process of the primary transcript and is referred to as mature RNA. "Messenger RNA (mRNA)" refers to RNA without introns and can be translated into proteins by the cell. "cDNA" refers to a double strand of DNA that is complementary and derived from mRNA.

"Sense of RNA" refers to the transcription of RNA that includes mRNA and can then be translated into proteins by the cell. "RNA derivative" refers to the transcription of RNA that is complementary to all or part of a primary primary transcript or mRNA and that blocks the expression of a target gene (U.S. Pat No. 5,107,065). The complementarity of an RNA in contradiction can be with any part of the transcription of the specific gene, i.e., in the 5 'non-coding sequence, 3' non-coding sequence, introns, or the coding sequence. "Functional RNA" refers to an RNA in contradiction, ribosomal RNA or other RNA that is not translated and still has an effect on cellular processes.

The term "operably linked" refers to the association of nucleic acid sequences in a single fragment of nucleic acid such that the function of one is affected by the other. For example, a promoter is operably linked to a coding sequence when it is capable of affecting the expression of the coding sequence (i.e., that the coding sequence is under transcriptional control of the promoter). Coding sequences can be operatively linked to regulatory sequences in normal orientation or in contradiction.

The term "expression" as used herein, refers to the transcription and stable accumulation of normal RNA (mRNA) or nonsense RNA derived from the nucleic acid fragment of the invention. Expression can also refer to the translation of mRNA into a polypeptide. "Inconsensus inhibition" refers to the production of transcripts of RNA in contradiction capable of suppressing the expression of the target protein. "Over-expression" refers to the production of a gene product in transgenic organisms that exceeds production levels in normal or non-transformed organisms. "Cosuppression" refers to the production of normal RNA transcripts capable of suppressing the expression of identical or substantially similar foreign endogenous genes (U.S. Patent No. 5,231,020).

Altered levels refers to the production of gene products in transgenic organisms in amounts or proportions that differ from those of normal or non-transformed organisms. "Mature protein" refers to a polypeptide processed post-translationally; i.e., one of which pre or propeptides present in the product of the primary translation have been excluded.

"Precursor protein" refers to the primary product of mRNA translation; i.e., with pre and propeptides still present. Pre and propeptides are not limited to intracellular localization signals.

A "chloroplast transit peptide" is an amino acid sequence which is translated in conjunction with a protein and directs the protein to the chloroplast or other types of plastids present in the cell in which the protein was made. "Chloroplast transit sequence" refers to a nucleotide sequence that encodes a transit peptide in chloroplasts. A "peptide signal" is an amino acid sequence which is translated in conjunction with a protein and directs the protein to the secretory system (Chrispeels, JJ, (1991) Ann. Rev. Plant Phys. Plant, Mol. Biol. : 21-53). If the protein is directed to a vacuole, a specific vacuolar signal (supra) can be added later, or if it is directed to the endoplasmic reticulum, an endoplasmic reticulum retention signal (supra) can be added. If the protein is directed to the nucleus, any present peptide signal must be removed and instead include a nuclear localization signal (Raikhel (1992) Plant Phys.100: 1627-1632).

"Transformation" refers to the transfer of a nucleic acid fragment to the genome of the host organism, resulting in genetically stable hereditary characters. Host organisms containing the transformed nucleic acid fragments are referred to as "transgenic" organisms. Examples of methods for plant transformation include Agrobacterium-mediated transformation (De Blaere et al (1987) Meth. Enzymol 143: 277) and accelerated particles or "bombardment of gene" transformation technology (Klein et.al. 1987) Nature (London) 327: 70-73; US Pat No. 4,945,050).

As described above, the standard recombinant DNA and the molecular cloning techniques used herein are well known in the art and are best described in Sambrook, J., Fritsch, E.F. and Maniatis, T. Molecular Cloning: A Laboratory Manual; Cold spring Harbor Laboratory Press: Cold Spring Harbor, 1989 (hereinafter "Maniatis").

Nucleic acid fragments encoding at least a portion of several biosynthetic amino acid enzymes in plants have been isolated and identified by comparison of cDNA sequences in randomly selected plants, to publish databases containing nucleotide and protein sequences using BLAST algorithms well known to those skilled in the art. Table 1 lists the biosynthetic amino acid enzymes described herein, and the designation of cDNA clones comprising the nucleic acid fragments encoding these enzymes.

TABLE 1 Biosynthetic amino acid enzymes 3 The nucleic acid fragments of the present invention can be used to isolate cDNAs and genes encoding homologous enzymes of the same species or of other plant species. The isolation of homologous genes using sequence dependent protocols is well known in the art. Examples of dependent sequence protocols include, but are not limited to, nucleic acid hybridization methods, and DNA and RNA amplification methods as exemplified for various uses of nucleic acid amplification technologies (eg, chain reaction of the polymerase, ligase chain reaction).

For example, genes encoding other amino acid biosynthetic enzymes, either cDNAs or genomic DNAs, could be isolated directly using all or a portion of the current nucleic acid fragments as DNA hybridization tests to protect libraries of any desired plant using good methodology. known by those qualified in art. Specific oligonucleotide tests based on current nucleic acid sequences can be designated and synthesized by methods known in the art (Maniatis). In addition, whole sequences can be used directly to synthesize DNA tests by methods known to skilled artisans such as random primer DNA labeling, notch translation, or final labeling techniques, or RNA tests using suitable transcription systems in vi tro. In addition, specific primers can be designed and used to amplify a part or the entire length of the current sequences. The products resulting from the amplification can be labeled directly during the amplification or labeling reactions after the amplification reactions, and used as tests for isolation of the full length of the cDNA or genomic fragments under appropriate severity conditions.

In addition, two short segments of the current nucleic acid fragments can be used in the polymerase chain reaction protocols to amplify long nucleic acid fragments by encoding DNA or RNA homologous genes. The polymerase chain reaction can also be performed in a library of cloned nucleic acid fragments wherein the sequence of one primer is derived from the current nucleic acid fragments, and the sequence of another primer takes advantage of the presence of regions of polyadenylic acid by the end of the 3 'of the mRNA precursor encoding plant genes. Alternatively, the second starter sequence may be based on sequences derived from the cloning vector. For example, skilled artisans can follow the RACE protocol (Frohman et al., (1988) NAS USA-85: 8998) to generate cDNAs by using PCR to amplify copies of the region between an isolated point in the transcript at the end of the 3 'or 5'. Initiators oriented in the 3 'and 5' direction can be designed from the current sequences.

Using adequate commercial systems 3 'RACE or 5' RACE (BRL), specific fragments 3 'or 5' cDNA can be isolated (Ohara et al., (1989) PANS USA 86: 5673; Loh et al., (1989) Science 243: 217). Products generated by the 3 'and 5' RACE procedures can be combined to generate complete cDNA chains (Frohman, M.A. and Martin, G.R., (1989) Techniques 1: 165).

The availability of the current nucleotide and the deduced amino acid sequences facilitate the safeguarding of cDNA in libraries of immunological expression. Synthetic peptides representing portions of the current amino acid sequences can be synthesized. These peptides can be used to immunize animals to produce polyclonal or monoclonal antibodies with specificity for peptides or proteins comprising the amino acid sequences. These antibodies can then be used to protect cDNA expression libraries to isolate full-length cDNA clones of interest (Lerner, R.A. (1984) Adv. Inmumol. 36: 1; Maniatis).

The nucleic acid fragments of the present invention can be used to create transgenic plants in which the disclosed biosynthetic enzymes are present at higher or lower levels than normal or in type cells or developmental stages in which they are not normally found. This would have the effect of altering the level of free minoacids in those cells.

The overexpression of the biosynthetic enzymes of the present invention can be completed by primary construction of chimeric genes in which the coding regions are operatively linked to promoters capable of directing the expression of the gene in the desired tissue at the desired stage of development. For reasons of convenience, the chimeric genes may comprise promoter sequences and leader translation sequences derived from the same genes. The 3 'non-coding sequences encoding the translation end signals can also be provided. The current chimeric genes may also comprise one or more introns in order to facilitate the expression of the gene.

The plasmid vectors comprising the current chimeric genes can then be manufactured. The plasmid vector option is dependent on the method that will be used to transform host plants. The skilled artisan is well aware of the genetic elements that must be present in the plasmid vector in order to successfully transform, selecting and spreading host cells containing the chimeric genes. The skilled artisan will also recognize that the events of the different independent transformations will result in different levels and patterns of expression ~ (Johns et al. (1985) EMBO J. 4: 2411-2418; De Almeida et al., (1989) Mol Gen. Genetics 218: 78-86), and in this way these multiple events must be safeguarded in order to obtain lines expressing the desired levels and patterns of expression. Such a guard can be carried out by Southern DNA analysis, Northern analysis of mRNA expression, Western analysis of protein expression, or phenotypic analyzes.

For some applications this may be helpful in directing current biosynthetic enzymes to different cellular compartments, or to facilitate their secretions from the cell. It is thus imagined that the chimeric genes described above can then be supplemented by altering the coding sequences to encode enzymes with appropriate intracellular target sequences such as transient sequences (Keegstra, K. (1989) Cell 56: 247-253), signal sequences or sequences encoding the location of the endoplasmic reticulum (Chrispeels, JJ, (1991) Ann. Rev. PlantPhys, Plan Mol. Biol. 42: 21-53), or added signals of nuclear localization (Raikhel, N. (1992) Plant Phys 100: 1627-1632) and / or with white sequences that are currently removed. While the cited references give examples of each of these, the list is not exhaustive and many useful white signals can be discovered in the future.

This may also be desirable to reduce or eliminate the expression of genes encoding the present biosynthetic enzymes in plants for some applications. In order to accomplish this, chimeric genes designed for co-suppression of current biosynthetic enzymes can be constructed by joining genes or gene fragments encoding the enzyme for plant promoter sequences. Alternatively, chimeric genes designed to express RNA in contradiction to all or part of the current nucleic acid fragments can be constructed by binding the gene fragment or genes in reverse orientation to promoter sequences in plant. Both co-suppression and chimeric genes in contrasense can be introduced into plants via transformation in which the expression of the corresponding endogenous genes are reduced or eliminated.

Biosynthetic enzymes of current amino acids (or portions of enzymes) can be produced in heterologous host cells, particularly in the cells of microbial hosts, and can be used to prepare antibodies for the enzymes by methods well known to those skilled in the art. The antibodies are useful for detecting the enzyme in cells in itself or in cell-in-vitro extracts. The preferred heterologous host cells for the production of the current amino acid biosynthetic enzymes are the microbial hosts. Microbial expression systems and expression vectors containing regulatory sequences that direct high levels of expression of foreign proteins are well known to those skilled in the art. Some of these could be used to construct chimeric genes for production of the present biosynthetic amino acid enzymes. These chimeric genes can then be introduced into appropriate microorganisms via transformation to provide high levels of enzyme expression. An example of a vector for high level expression of the current biosynthetic amino acid enzymes in a bacterial host is provided (example 11).

Additionally, biosynthetic enzymes of current plant amino acids can be used as targets to facilitate the design and / or identification of enzyme inhibitors that may be useful as herbicides. This is desirable because the enzymes described here catalyze several steps in a route initiating the production of several essential amino acids. Therefore, inhibition of the activity of one or more of the enzymes described herein could initiate the inhibition of sufficient amino acid biosynthesis to inhibit the development of the plant. Thus, the plant's current amino acid biosynthetic enzymes could be appropriate for the discovery and design of new herbicides.

All or a substantial portion of the nucleic acid fragments of the present invention can also be used as tests to map genes that are genetically and physically part of them, and as markers for traits attached to those genes. Such information can be useful in the production of plants in order to develop lines with desired phenotypes. For example, current nucleic acid fragments can be used as restriction fragment extension polymorphism markers. Southern blots (Maniatis) of digested restriction of plant genomic DNA can be tested with the nucleic acid fragments of the present invention. The resulting pattern bands can also be subjected to genetic analysis using computer programs such as MapMaker (Lander et al. , (1987) Genomics 1: 174-181) in order to construct a genetic map. In addition, the nucleic acid fragments of the present invention can be used to test Southern blots containing restriction-treated endonucleases of genomic DNAs from a group of individuals represented as parents and progeny of a defined genetic cross. Segregation of the DNA polymorphism is annotated and used to calculate the position of the current nucleic acid sequence in the genetic map previously obtained using this population (Botstein, D. et al., (1980) Am. J. Hum. Genet. 32: 314-331) ..

The production and use of the gene-derived plant tests for use in genetic mapping is described in R. Bernatsky, R. And Tanksley, S.D. (1986) Plant Mol. Biol. Repórter 4 (1): 37-41. Numerous publications describe the genetic mapping of specific clones of cDNA using the methodology outlined above or variations thereof. For example, interbreeding F2 populations, populations of later crosses, random mating populations, nearby isogenic lines, and other groups of individuals can be used to map. Such methodologies are well known to those skilled in the art.

Nucleic acid assays derived from the current nucleic acid sequence can be used for physical mapping (ie, placement of sequences on physical maps; see Hoheisel, JD, et al., Tn: Nonmammalian Genomic Analysis: A Practical Guide, Academic press 1996 , pp. 319-346, and references cited here).

In another embodiment, nucleic acid assays derived from current nucleic acid sequences can be used in direct fluorescence in situ (FISH) hybridization mapping (Trask, B: J: (1991) Trends Genet., 7: 149-154) . Although current methods of FISH mapping favor the use of long clones (Several to several hundred KB; see Laan, M. et al. (1995) Genome Research 5: 13-20) improvements in sensitivity may allow the performance of the FISH mapping using shorter tests.

A variety of methods based on nucleic acid amplification of genetic and physical mapping can be conducted using the current nucleic acid sequences.

Examples include allele-specific amplification (Kazazian, HH (1989) J. Lab. Clin. Med. 114 (2) .95-96) polymorphism of PCR amplified fragments (CAPS, Sheffield, VC et.al. (1993) Genomics 16,325-332), linkage of specific alleles (Landergre, U. et al. (1988) Science 241: 1077-1080), nucleotide extension reactions (Sokolov, BP (1990) Nucleic Acid Res. 18: 3671), Hybrid Mapping Radiation (Walter, MA et al. (1997) Nature genetics 7: 22-28) and Happy Mapping (Dear, PH 7And Cook, PR (1989) Nucleic Acid Res. 17: 6795-6807). For these methods, the sequence of a nucleic acid fragment is used to design and produce primer pairs for use in the amplification reaction or primer extension reactions. The design of such initiators is well known to those skilled in the art. In methods employing genetic mapping based. in PCR, it may be necessary to identify differences in the DNA sequence between parents of the cross map in the region corresponding to the current nucleic acid sequence. This, however, is not generally necessary for mapping methods.

The loss of function of mutant phenotypes can be identified by current cDNA clones either by disruption protocols of a target gene or by identification of specific mutants for these genes contained in a maize population carrying mutations in all possible genes (Ballinger and Benzer, (1989) Proc. Nati, Acad. Sci. USA 86.9402, Koes et al., (1995) Proc. Nati, Acad. Sci USA 92.8149, Bensen et al., (1995) -Plant Cell 7:75). The last approach can be accomplished in two ways. First, short segments of the current nucleic acid fragments can be used in the polymerase chain reaction protocols in conjunction with a mutation of the labeled primer sequence in DNAs prepared from a population of plants in which mutant transposons or some other element causing mutation in DNA has been introduced, (see Bensen, supra). Amplification of a specific DNA fragment with these primers indicates the insertion of labeled labeling mutation element in or near the plant gene encoding dihydrodipicolinate reductase, diaminopimelate epimerase, threonine synthase, threonine deaminase, or S-adenosylmethionine synthetase. Alternatively, the current nucleic acid fragment can be used as a hybridization test against the PCR amplification products generated from the mutated population using the tagged mutant primer sequence in conjunction with an arbitrary genomic site primer, such as that for an adapter. synthetic restriction enzyme anchor site. With either method, a plant containing a mutation in an endogenous gene encoding a dihydrodipicolinate reductase, diaminopimelate epimerase, threonine synthase, threonine deaminase, or S-adenosylmethionine synthetase can be identified and obtained. This mutant plant can then be used to determine or confirm the natural function of the product gene dihydrodipicolinate reductase, diaminopimelate epimerase, threonine synthase, threonine deaminase, and S-adenosylmethionine synthetase.

EXAMPLES The present invention is further defined in the following examples, in which all parts and percentages are by weight and degrees Celsius, unless stated otherwise. It should be understood that these examples, while indicating preferred embodiments of the invention, are given solely for the purpose of illustration. From the discussions before these examples, one skilled in the art can find out the essential characteristics of this invention, and without leaving the spirit and scope thereof, can make several changes and modifications of the invention to adapt this to various uses and conditions.

EXAMPLE 1 Composition of cDNA libraries; isolation and sequencing of cDNA clones cDNA libraries representing mRNAs were prepared from various tissues of corn, rice, soybeans and wheat. The characteristics of the libraries are described below.

TABLE 2 * These libraries were essentially normalized as described in U.S. Pat. No. 5,482,845. ** Application of 6-iodo-2-propoxy-3-propyl-4 (3H) -quinazolinone; Synthesis and methods of use This compound is described in USSN 08 / 545,827, incorporated herein by reference.

The cDNA libraries were prepared in UNI-ZAP ™ XR vectors according to the manufacturing protocol (Stratagene Coning Systems, La Jolla, CA). Conversion of the UNI-ZAP ™ XR libraries into the plasmid libraries was carried out according to the protocol provided by Stratagene. In the conversion, the cDNA inserts were contained in the plasmid vector pBluescript. The cDNA inserts from randomly selected bacterial colonies containing recumbent pBluescript plasmids were amplified via the polymerase chain reaction using primers specific for vector sequences flanking the inserted cDNA sequences, or the plasmid DNA was prepared from bacterial cell culture. Amplified insert DNA or plasmid DNAs were sequenced in sequencing reactions of the labeled primer to generate partial cDNA sequences (labeled expressed sequence or "ESTs", see Adams, M.D. et al., (1991) Science 252: 1651). The resulting ESTs were analyzed using a Model 377 fluorescent sequencer Perkin Elmer.

EXAMPLE 2 Identification and characterization of cAPN clones ESTs encoding plant amino acid biosynthetic enzymes were identified by BLAST conducted investigations (Basic Local Alignation Seach Tool; Altschul, S.F., et al., (1993) J. Mol. Biol. 215í 403-410; see also www.ncbi.nlm.nih.gov/BLAST/) for similarity for sequences contained in the BLAST database "nr" (including all non-redundant translations) GenBank CDS, sequences derived from Brookhaven protein DataBank 3-dimensional structure, the main release of the protein sequence database SWISS-PROT, EMBL, and DDBJ databases). The cDNA sequences obtained in Example 1 were analyzed for similarity for all publicly available DNA sequences contained in the "nr" database using the BLASTN algorithm provided by the National Center for Biotechnology Information (NCBI). The DNA sequences were translated into all reading frames and compared by similarity for all publicly available protein sequences contained in the "nr" database using the BLASTX algorithm (Gish, W. And States, DJ (1993) Nature Genetics 3: 266-272) provided by the NCBI. For convenience, the P-value (probability) of observing a match of the cDNA sequences for a sequence contained in the database searched merely by chance as calculated by BLAST are reported here as "pLog" values, which represents the negative of the logarithm of the P-value reported. Therefore, the higher the pLog value, the greater probability that the cDNA sequence and the BLAST "hit" represent homologous proteins.

The BLASTX search using nucleotide sequences from clones csin.pk0042.a3 and rls2.pk0017.d3 revealed similarity of proteins encoded by cDNA for the enzyme Dihydrodipicolinate reductase of Synechocystis sp. (DDBJ Accession No. D90899). The BLAST pLog values were 12.60 and 11.68 for csin.pk0042.a3 and rls2.pk0017.d3, respectively.

The amino acid sequence declared in SEQ ID NO: 2 was evaluated by BLASTP, yielding a pLog value of 36.72 against the Dihydrodipicolinate reductase sequence of Synechocystis sp. The sequence of a portion of cDNA inserted from clone rls2.pk0017.d3 is shown in SEQ ID NO: 3; the deduced amino acid sequence of this cDNA is shown in SEQ ID NO: 4. Figure 2 shows an alignment of the amino acid sequences declared in SEQ ID NO: 2 and the dihydrodipicolinate reductase sequence of Synechocystis sp. (SEQ ID NO: 5). SEC ID NO: 2 it is 40% identical for the dihydrodipicolinate reductase sequence of Synechocystis sp. (SEC • ID NO: 5). Sequence alignments were carried out by the Clustal method of alignment (Higgins, DG and Sharp PM (1989) CABIOS 5: 151-153), using the Megalign program of the bioinformatics computing department LASARGENE (DNASTAR Inc., Madison, Wl) . Percent sequence identity calculations were carried out by the Jotun Hein method (Hein, JJ (1990) Meth., 183: 626-645) using the Megalign program of the LASARGENE bioinformatics computing department (DNASTAR Inc., Madison , Wl).

These sequences represent the first sequences encoding plant dihydrodipicolinate reductase.

(rls48.pk0036.hl0), and a whole soybean diaminopimelate epimerase (se2.pk0005.f1, ses8w.pk0010.hll, sfll.pk0031.h3, and sgslc.pk002.kl2), and a portion of wheat diaminopimelate epimerase (wlm2 .pk0030.g4).

EXAMPLE 8 Expression of Chimeric Genes in Monocotyledon Cells.

A chimeric gene comprising a cDNA encoding a plant biosynthetic enzyme in sense orientation with respect to the 27 kD corn zein promoter that is located 5 'to the cDNA fragment, and the 3' terminal of 10 kD zein that is located 3 ' to the fragment of cDNA, it can be constructed. The cDNA fragment of this gene can be generated by polymerase chain reaction (PCR) of the cDNA clone using appropriate oligonucleotide primers and under appropriate experimental conditions. The cloning sites (Ncol or Smal) can be incorporated into the oligonucleotides to provide proper orientation of the DNA fragment when inserted into the digested vector pML103 as described below. The amplified DNA can then be digested with Ncol and Smal restriction enzymes and fractionated on 0.7% low melting point agarose gel in 40 mM Tris-acetate, pH 8.5, 1 mM EDTA. An appropriate band of can be excised from the gel, melted at 68 ° C and combined with a 4.9 kb fragment of Ncol-Smal from plasmid pML 103. Plasmid pML 103 has been deposited under the terms of the Budapest treaty at ATCC (American Type Culture Collection, 10801 University Boulevard, Manassas, VA 20110-2209), and has an accession number ATCC 97366. The DNA segment of pML103 contains a 1.05 kb Ncol-Smal promoter fragment of the 27 kD corn zein gene. and a 0.96 kb fragment of S al-Sall from the 3 'terminus of the 10 kD corn zein gene in the vector pGem9Zf (+) (Promega). The vector and the inserted DNA can be ligated at 15 ° C during the night, essentially as described (Maniatis). The ligated DNA can then be used to transform E. coli XLl-Blue (Epicurian Coli XL-1 Blue, Stratagen). Bacterial transformants can be protected by restriction enzyme digestion of the plasmid DNA and analysis of the limited nucleotide sequence using the dideoxy chain termination method (Sequenase ™ DNA Sequencing Kit; U.S. Biochemical). The construction of the resulting plasmid comprises a chimeric gene encoding, in the 5 'and 3' direction, the 27 kD corn zein promoter, a cDNA fragment encoding a plant amino acid biosynthetic enzyme, and the 3 'region of zein 10 kD.

The chimeric gene described above can be introduced into maize cells by the following procedure. Immature maize embryos can be dissected from developed cariopses derived from crosses of maize lines born H99 and LH132. Embryos are isolated 10 to 11 days after pollination when they are 1.0 to 1.5 mm in length. The embryos are then placed with the sides of the shafts down and in contact with the solidified agarose medium N6 (Chu et al., (1975) Sci. Sin. Peking 16: 659-668). The embryos are kept in the dark at 27 ° C. The crumbly embryogenic callus consisting of undifferentiated masses of cells with pro-embrionoid and embryo-born suspensory structures proliferates from the scutellum of these immature embryos. The embryogenic callus isolated from the primary explant can be cultured in an N6 medium and subcultured in this medium every 2 or 3 weeks.

Plasmid p35S / Ac (obtained from Peter Eckes, Hoechst Ag, Frankfurt, Germany) can be used for transformation experiments to provide a selectable marker. This plasmid contains the Pat gene (see European Patent Publication 0 242 236) which encodes phosphinothricin acetyl transferase (PAT). The enzyme PAT confers resistance to inhibitors of glutamine synthetase herbicides such as phosphinothricin. The pat gene in p35S / Ac is under the control of the 35S promoter of the Cauliflower Mosaic Virus (Odell et al., (1985) Nature 313: 810-812) and the 3 'region of the T-DNA nopaline synthase gene of the Ti plasmid of Agrobacterium tumefaciens.

The method of bombardment of particles (Klein et al., (1987) Nature 327: 70-73) can be used to transfer genes to callus culture cells. According to this method, gold particles (1 μm in diameter) are coated with DNA using technique 8 following. Ten μg of the DNA plasmids are added to 50 μL of a suspension of gold particles (60 mg per mL). Calcium chloride (50 μL of 2.5 M solution) and spermidine free base (20 μL of a l.O M solution) are added to the particles. The suspension is vigorously stirred during the addition of these solutions. After 10 minutes, the tubes are centrifuged for a short time (5 sec at 15,000 rpm) and the supernatant removed. The particles are suspended in 200 μL of absolute ethanol, centrifuged again and the supernatant removed. The ethanol rinsing is performed again and the particles resuspended in a final volume of 30 μL of ethanol. An aliquot (5 μL) of gold particles coated with DNA can be placed in the center of a Kapton ™ disc (Bio-Rad Labs). The particles are then accelerated into the corn tissue with a Biolistic ™ PDS-1000 / He (Bio-Rad Instruments, Hercules CA), using a helium pressure of 1000 psi, a gap distance of 0.5 cm and a throw distance of 1.0 cm.

For the bombardment, the embryogenic tissue is placed on filter paper on a N6 solidified agarose medium. The fabric is arranged as a thin layer and covered with a circular area about 5 cm in diameter. The petri dish containing the fabric can be placed in the camera of the PDS-1000 / He approximately 8 cm from the limiter screen. The air in the chamber is then evacuated to a vacuum of 28 inches Hg. The macrocarrier is accelerated with a helium shock wave using a rupture membrane that bursts when the helium pressure in the shock tube reaches 1000 psi.

Seven days after the bombardment the tissue can be transferred to an N6 medium containing glufosinate (2 mg per liter) and lacks casein and proline. The tissue continues to grow slowly in this medium. After an additional 2 weeks the tissue can be transferred to a fresh N6 medium containing glufosinate. After 6 weeks, areas of about 1 cm in diameter of callus growing effectively can be identified in some of the plates containing a medium supplemented with glufosinate. These calluses can continue to grow when subcultured on a selective medium.

Plants can be regenerated from transgenic callus first by transfer of tissue clusters to an N6 medium supplemented with 0.2 mg per liter of 2,4-D. After two weeks the tissue can be transferred to a regenerated medium (Fromm et al., (1990) Bio / Technology 8: 833-839).

EXAMPLE 9 Expression of the Chimeric Genes in Dicotyledonous Cells A box or expression cassette of a specific seed composed of the promoter and terminator of the gene expression coding for the β subunit of the phaseolin stored protein of the seed of the bean Phaseolus vulgaris (Doyle et al (1986) J. Biol. Chem. 261 : 9228-9238) can be used for expression of the biosynthetic enzymes of current amino acids in transformed soybeans. The phaseolin box includes about 500 nucleotides upstream (5 ') of the translation initiation codon and about 1650 nucleotides of the terminal (3') end of the phaseolin translation stop codon. Between the 5 'and 3' regions are sites of unique Ncol restriction endonucleases (which include the translation initiation codon ATG), Sma I, Kpn I and Xba I. The entire box is flanked by Hind III sites.

The cDNA fragment of this gene can be generated by polymerase chain reaction (PCR) of the cDNA clone using appropriate oligonucleotide primers. The cloning sites can be incorporated into the oligonucleotides to provide orientation of the DNA fragment when inserted into the expression vector. The amplification is then carried out, and the isolated fragment is inserted into a vector pUCld transporting the expression box of the seed.

Biosynthetic enzymes of plant amino acids are known to be localized in chloroplasts. In this way, for those enzymes (or polypeptides representing part of the current amino acid biosynthetic enzymes) that lack a white chloroplast signal, the DNA fragment can be inserted into the expression vector that can be synthesized by PCR with primers encoding a white chloroplast signal. For example, a chloroplast transit sequence equivalent to the cts of the small subunit of ribulose 1, 5-bisphosphate carboxylase of soybean (Berry-Lowe et al (1982) J. Mol. Appl. Gent., 483-49d) It can be used.

Soybean embryos can then be transformed with expression vectors comprising sequences encoding a plant amino acid biosynthetic enzyme. To induce tic embryos, cotyledons, 3-5 mm in length dissected from the sterilized surface, immature soybean seeds A2872, can be grown in light or in the dark at 26 ° C on an appropriate agar medium for 6 days. -10 weeks. The tic embryos which produce secondary embryos are then excised and placed in a suitable liquid medium. After repeated selection for groupings of tic embryos which multiplied early, embryos in globular stage, suspensions are maintained as described below.

Soybean embryogenic suspension cultures can be maintained in 35 mL of liquid medium on a rotary shaker, at 150 rpm, at 26 ° C with fluorescent lights on a program of 16: 8 hours day / night. The cultures are subcultured every two weeks by inoculating approximately 35 mg of tissue into 35 mL of liquid medium.

Soybean embryogenic suspension cultures can then be transformed by the particle bombardment method (Kline et al (1987) Nature (London) 327.70, US Patent No. 4,945,050). An instrument of Du Pont Biolistic ™ PDS100 / HE (retro-fitted helium) can be used for these transformations.

A selected marker gene which can be used to facilitate the transformation of soybean is a chimeric gene composed of the 35S promoter of the Cauliflower Mosaic Virus (Odell et al. (1985) Nature 313: 810-812)), the hygromycin gene phosphotransferase of plasmid pJR225 (from E. coli; Gritz the al. (1983) Gen 25: 179-188) and the 3 'region of the nopaline synthase gene of the T-DNA or of the Ti plasmid of Agrobacterium tumefaciens. The seed expression box comprising the 5 'region of the phaseolin, the fragment encoding the biosynthetic enzyme and the phaseolin of the 3' region can be isolated as a restriction fragment. This fragment can then be inserted into a single restriction site of the marker gene transporter vector.

For 50 μL of 60 mg / mL of a suspension of particles of 60 mg / mL of gold is added (in order): 5 μL DNA (1 μg / μL), 20 μl of spermidine (0.1 M), and 50 μL of CaCl2 (2.5 M). The particle preparation is then stirred for 3 minutes, centrifuged in a microfuge for 10 seconds and the supernatant removed. The particles of DNA-coated ones are then washed once in 400 μL of 70% ethanol and resuspended in 40 μL of anhydrous ethanol. The DNA / particle suspension can be sonicated three times for one second each time. Five μL of the gold particles covered with DNA are then loaded onto each macro transporter disc.

Approximately 300-400 mg of two-week-old suspension culture is placed in an empty 60x15 mm petri dish and the residual liquid removed from the tissue with a pipette. For each transformation experiment, approximately 5-10 tissue plates are normally bombarded. The rupture pressure of the membrane is adjusted to 1100 psi and the chamber is evacuated to a vacuum of 28 inches of mercury. The fabric is placed approximately 3.5 inches apart from the retention screen and bombarded three times. In subsequent bombardment, the tissue can be divided in half and placed back into the liquid and cultured as described above.

Five to seven days after the bombardment, the liquid medium can be exchanged with fresh medium, eleven to twelve days after bombardment with fresh medium containing 50 mg / mL of hygromycin. This selective medium can be refreshed every week. - Seven to eight weeks after the bombardment, the transformed, green tissue can be observed growing from necrotic embryogenic clusters. The isolated green tissue is removed and inoculated into individual flasks to generate new transformed embryogenic suspension cultures, propagated by cloning. Each new line can be treated as an independent transformation event. These suspensions can be subcultured and maintained as groups of immature or regenerated embryos within whole plants by maturation and germination of individual somatic embryos.

EXAMPLE 10 Analysis of the Amino Acid Content of the Transformed Plant Seeds To analyze by expression of the chimeric genes in seeds and for the consequences of expression on the amino acid content in the seeds, a seed meal can be prepared by any number of methods suitable for those skilled in the art. The seed meal can be partially or completely defatted, via extraction of hexane for example, if desired. The protein extracts can be prepared from the flour and analyzed by enzymatic activity. Alternatively the presence of. any of the expressed enzymes can be immunologically tested by methods well known to those skilled in the art. To measure the composition of free amino acids in seeds, free amino acids can be extracted from the flour and analyzed by methods well known by those skilled in the art (Bielinski et al. (1996) Anal. Biochem. 17: 278-293) . The composition can then be determined using any commercially available amino acid analyzer. To measure the free amino acid composition of the seeds, the flour containing both bound protein and free amino acids can be hydrolyzed by acid to release the amino acids linked to the protein and the composition can be determined using any commercially available amino acid analyzer. The seeds expressing the biosynthetic enzymes of current amino acids and with altered content of lysine, threonine, methionine, cysteine and / or isoleucine as compared to wild type seeds can then be identified and propagated.

To measure the free amino acid composition of the seeds, the free amino acids can be extracted from 8-10 milligrams of seed meal in 1.0 mL of methanol / chloroform / water mixed in a ratio of 12v / 5v / 3v (MCW) at temperature ambient. The mixture can then be vigorously stirred and then centrifuged in an eppendorf microcentrifuge for about 3 minutes; approximately 0.8 mL of the supernatant is then decanted. For this supernatant, 0.2 mL of chloroform followed by 0.3 L of water are added. The mixture is then vigorously stirred and centrifuged in an eppendorf microcentrifuge for about 3 minutes. The upper aqueous phase, approximately 1.0 mL, can then be removed and dried in a Savant Speed Vac concentrator. The samples are then hydrolysed in 6N hydrochloric acid, 0.4% ß-mercaptoethanol under nitrogen for 24 h at 110-120 ° C. Ten percent of the sample can then be analyzed using a Beckman Model 6300 amino acid analyzer using posterior detection in ninhydrin column. The relative free amino acid levels in the seeds are then compared in this manner as ratios of lysine, threonine, methionine, cysteine, and / or isoleucine to leucine, using leucine as an internal standard.

EXAMPLE 11 Expression of Chimeric Genes in Microbial Cells The cDNAs encoding the biosynthetic enzymes of current plant amino acids can be inserted into the expression vector pET24d (Novagen) T7 of E. coli. The DNA plasmid containing a -cDNA can be appropriately digested to release the nucleic acid fragment encoding the enzyme. This fragment can be purified on a NuSieve GTG ™ 1% low melting agarose gel (FMC). The buffer and the agarose contain 10 μg / ml ethidium bromide for visualization of the DNA fragment. The fragment can be purified from the agarose gel by digestion with GELase ™ (Epicenter Technology) according to the manufacturer's instructions, precipitated with alcohol, dried and suspended in 20 μL of water. Suitable oligonucleotide adapters can be ligated to the fragment using T4 DNA ligase (New England Biolabs, Beverly, MA). The fragment containing the ligated adapters can be purified from the excess of adapters using low melt agarose as described above. The vector pET24d is digested, dephosphorylated with alkaline phosphatase (NEB) and deproteinized with phenol / chloroform as * described above. The pET24 vector prepared and the fragment can then be ligated at 16 ° C for 15 hours followed by transformation into DH5 electrocompetent cells (GIBCO BRL). Transformants can be selected on agar plates containing 2xYT medium and 50 μg / mL kanamycin. The transformants containing the gene encoding the enzyme are then protected for correct orientation with respect to the pET24d T7 promoter by restriction of enzyme analysis.

Clones in the correct orientation with respect to the T7 promoter can be transformed into BL21 (DE3) competent cells (Novagen) and selected on 2xYT agar plates containing 50 μg / mL kanamycin. A colony appeared from this transformation construct can be grown overnight at 30 ° C in a 2xYT medium containing 50 μg / mL kanamycin. The culture is then diluted twice with fresh medium, allowing re-growth for 1 h, and inducing by addition of isopropylthiogalactopyranoside to a final concentration of ImM. The cells are then harvested by centrifugation after 3 h and re-suspended in 50 μL of 50 mM Tris-HCl at pH 8.0 containing 0.1 mM DTT and 0.2 mM phenyl methylsulfonyl fluoride. A small amount of a 1 mm glass bed can be added and the mix sonicated 3 times for about 5 seconds each time with a micro-test sonicator. The mixture is centrifuged and the protein concentration of the supernatant determined. One μg of protein from the soluble fraction of the culture can be separated by SDS-polyacrylamide gel electrophoresis. The gels can be observed by protein bands migrating to the expected molecular weight.

EXAMPLE 12 'Evaluation of Compounds for their Ability to Inhibit the Activity of a Plant Amino Acid Biosynthetic Enzyme The plant amino acid biosynthetic enzymes described herein can be produced using any number of known methods for that enabled in the art. Such methods include, but are not limited to, bacterial expression as described in Example 6, or expression in eukaryotic cell cultures, in-plant, and using viral expression systems in suitably infected organisms or cell lines. Current enzymes can be expressed separately as mature proteins, or can be co-expressed in E. coli or other suitable means of expression. In addition, whether expressed separately or in combination, current enzymes can be expressed either in mature forms of the proteins as observed in vivo or as a fusion of proteins bound by covalence to a variety of enzymes, proteins or affinity residue. Associations of common fusion proteins include glutathione S-transferase ("GST"), theorexin ("Trx"), protein bound maltose, and C-and / or N-terminal hexahistidine polypeptide ("(HisJß").

The fusion of proteins can be carried out with a recognized site of protease at the melting point in such a way that the fusion partners can be separated by digestion by proteases to yield intact mature enzymes. Examples of such proteases include thrombin, enterokinase and factor Xa. However, any protease can be used specifically by separating the peptide connected to the fusion protein and the biosynthetic enzyme.

The purification of the current enzymes, if desired, can utilize any number of familiar separation technologies for those skilled in the art of protein purification. Examples of such methods include, but are not limiting, homogenization, filtration, centrifugation, heat denaturation, ammonium sulfate precipitation, salt precipitation, pH precipitation, ion exchange chromatography, hydrophobic interaction chromatography and affinity chromatography, where the ligand by affinity represents a substrate, analog substrate or inhibitor. When the enzymes are expressed as protein fusion, the purification protocol may include the use of an affinity resin which is specified by the protein fusion residue bound to an expressed enzyme or an affinity resin containing ligands which are specific for the enzyme. For example, an enzyme can be expressed as a protein fusion coupled to the thioredoxin C-terminus. In addition, a peptide (His) 6 can be constructed in the N-terminus of the fused thioredoxin moiety to provide additional opportunities for affinity purification. Other suitable affinity resins could be synthesized by binding the appropriate ligands to any suitable resin such as Sepharose-4B. In an alternate modality, a thioredoxin protein fusion can be eluted using dithiothreitol; however, elution can be performed using reagents which interact to displace the thioredoxin from the resin. These reagents include β-mercaptoethanol or another reduced thiol.

The fusion of eluted protein can be subject to further purification by the traditional methods set forth above, if desired. The proteolytic separation of the thioredoxin fusion protein and the biosynthetic enzyme can be performed after the protein fusion is purified or while the protein is still bound to the ThisBond ™ affinity resin or to another resin.

The partially purified or purified, crude enzyme, either alone or as a protein fusion, can be used in assays for the evaluation of compounds for their ability to inhibit the enzymatic activation of the plant amino acid biosynthetic enzymes described herein. The assays can be conducted under well-known experimental conditions which allow optimal enzymatic activity. Examples of assays for many of these enzymes can be found in Methods in Enzymology Vol. V, (Colowich and Kaplan eds) Academic Press, New York or Methods in Enzymology Vol. XVII, (Tabor and Tabor eds) Academic Press, New York.
