Definitions
- the present invention provides compositions for attenuating the function of atypical CYS HIS rich thioredoxin 4 (ACHT4), a light-regulated protein expressed in plants and algae that controls starch storage in chloroplast, and methods for increasing plant and algae growth and yield.
- ACHT4 atypical CYS HIS rich thioredoxin 4
- a light-regulated protein expressed in plants and algae that controls starch storage in chloroplast ACHT4
- Genetically modified plants with improved agronomic traits such as yield, pest resistance, herbicide tolerance, improved seed compositions, and the like are desired by both farmers and consumers. Although considerable efforts in plant breeding have provided significant gains in desired phenotypes, the ability to introduce specific DNA into plant genomes provides further opportunities for generation of plants with improved and/or unique phenotypes. The ability to develop genetically modified plants with improved traits depends in part on the identification of genes that are useful in recombinant DNA constructs for production of transformed plants with improved properties.
- One genetic modification that would be economically desirable would be to increase the growth and yield production of the plant. There is a need to develop a method for increasing growth in plants, regardless of the locale or the environmental conditions.

- host cells that contain a vector, e.g., a DNA plasmid and support the replication and/or expression of the vector.
- Host cells may be prokaryotic cells such as E. coli , or eukaryotic cells such as yeast, plant, insect, amphibian, or mammalian cells.
- host cells are monocotyledonous or dicotyledonous plant cells. In other embodiments monocotyledonous host cell is a maize host cell.
- the host cell utilized in the methods of the present invention is transiently transfected with the nucleic acid molecules of the invention.
- the host cell utilized in the methods of the present invention is a plant protoplast.
- Plant protoplasts are plant cells that had their entire plant cell wall enzymatically removed prior to the introduction of the molecule of interest. The complete removal of the cell wall disrupts the connection between cells producing a homogenous suspension of individualized cells which allows more uniform and large scale transfection experiments. This comprises, but is not restricted to protoplast fusion, electroporation, liposome-mediated transfection, and polyethylene glycol-mediated transfection. Protoplast preparation is therefore a very reliable and inexpensive method to produce millions of cells.
- the plant protoplast is derived from one of the following genuses: Acorus, Aegilops, Allium, Amborella, Antirrhinum, Apium, Arabidopsis, Arachis, Beta, Betula, Brassica, Capsicum, Ceratopteris, Citrus, Cryptomeria, Cycas, Descurainia, Eschscholzia, Eucalyptus, Glycine, Gossypium, Hedyotis, Helianthus, Hordeum, Ipomoea, Lactuca, Linum, Liriodendron, Lotus, Lupinus, Lycopersicon, Medicago, Mesembryanthemum, Nicotiana, Nuphar, Pennisetum, Persea, Phaseolus, Physcomitrella, Picea, Pinus, Poncirus, Populus, Prunus, Robinia, Rosa, Saccharum, Schedonorus, Secale, Sesamum, Solanum, S

RNA encoded by the introduced nucleic acid construct may then be transcribed in the cell and descendants thereof, including cells in plants regenerated from transformed material. A gene stably incorporated into the genome of a plant is passed from generation to generation to descendants of the plant, so such descendants should show the desired phenotype.
- germ line cells may be used in the methods described herein rather than, or in addition to, somatic cells.
- the term “germ line cells” refers to cells in the plant organism which can trace their eventual cell lineage to either the male or female reproductive cell of the plant.
- Other cells referred to as “somatic cells” are cells which give rise to leaves, roots and vascular elements which, although important to the plant, do not directly give rise to gamete cells. Somatic cells, however, also may be used. With regard to callus and suspension cells which have somatic embryogenesis, many or most of the cells in the culture have the potential capacity to give rise to an adult plant.
- the cells in the callus and suspension can therefore be referred to as germ cells.
- certain cells in the apical meristem region of the plant have been shown to produce a cell lineage which eventually gives rise to the female and male reproductive organs.
- the apical meristem is generally regarded as giving rise to the lineage that eventually will give rise to the gamete cells.
- An example of a non-gamete cell in an embryo would be the first leaf primordia in corn which is destined to give rise only to the first leaf and none of the reproductive structures.

- Such activity might be important for the rationing of photosynthates to starch and sugars exported from the chloroplast during the day.
- such activity may regulate the levels of starch to be used as a transient pool for reduced carbon in a fluctuating light environment.
- We tested this hypothesis by subjecting the plants to small fluctuations of light intensity during the day.
- APS1-ACHT4 RI levels declined within 5 min, and rose again when the light intensity was switched back to 50 ⁇ E*m ⁇ 2*s ⁇ 1 ( FIG. 3A ).
- the C-terminus of ACHT4 is important for its reaction with APS1
- FIG. 4A We then assessed whether the distinct 47-amino acid-long ACHT4 C-terminus ( FIG. 4A ) is responsible for its in planta differences from ACHT1, by analyzing the 2-Cys Prx and APS1 RIs in plants expressing ACHT4 lacking the C-terminus (ACHT4 ⁇ C). Notably, the ACHT4 ⁇ C form reacted with 2-Cys Prx, and formed the two intermolecular disulfide-linked 2-Cys Prx ACHT4 RIs, but failed altogether to interact with APS1 ( FIG. 2B ). The preferential reaction of ACHT4 ⁇ C with the 2-Cys Prx and not with APS1 was maintained throughout the transition from night to day ( FIG. 4C ).
- ACHT4 and ACHT1 are thylakoid-associated proteins.
- Protein blot analysis showed that ACHT1 was primarily found in both the grana and the stroma lamella domains, whereas ACHT4 was mainly present in the stroma lamella domain and was undetectable in the grana ( FIG. 4D ), further promoting distinct roles of ACHT4 and ACHT1.
- ACHT4 ⁇ C The membrane association of ACHT4 ⁇ C was then analyzed to determine whether ACHT4 localization is influenced by its unique C-terminus. Only a small increase in the partitioning of ACHT4 ⁇ C to the grana margins was observed, suggesting that the ACHT4 C-terminus deletion effect on its disulfide exchange reaction with APS1 was direct and not mediated via its thylakoid domain localization.
- AtACHT4 ⁇ C-OE, AtACHT4-OE and WT lines were grown under long day (18 h/6 h of light/dark cycle at 21° C./18° C.) for 4 weeks.
- the plants shoot was excised and fresh weight (FW) were recorded.
- the tissues were dried at 60° C. for 4 days and dry weight (DW) were recorded.
- the FW of AtACHT4 ⁇ C-OE plants was increased by 10.6% ( FIG. 6A ) and the DW was increased by 9.1% over those of WT ( FIG. 6B ), indicating that AtACHT4 ⁇ C stimulates the export of photosynthates from the chloroplast which are then directed toward growth.
- the FW of AtACHT4 OE plants was decreased by 10.9% ( FIG. 6A ) and the DW was increased by 11.5% over those of WT ( FIG. 6B ), confirming that the C-terminus of ACHT4 attenuates growth.
- Arabidopsis has one paralog of ACHT4 where other crop plants, including potato, maize, rice, barley, wheat, sorghum , castor, bean, rapeseed, cotton, soybean, beat, banana, chili, chickpea, tomato, African oilpalm, Foxtail millet, cassava and the algae Chlamydomonas and Chlorella have one to five paralogs ( FIG. 7 ).
- HA Human influenza hemagglutinin tag was fused in frame at the C-terminus of each of the protein coding sequences. All four StACHT4::pART7 and StACHT4-2 ⁇ C:: pART7 constructs were digested with NotI and subcloned into pART27 plant expression vector ( FIG. 11 ) and used to transform potato leaf discs ( Solanum tuberosum cv. Desiree) using a standard agrobacterium -based transformation protocol. Positive transformants were identified by PCR analysis and protein expression was verified by immunoblot analysis using anti-HA antibody.
- the StACHT4-2 ⁇ C-OE and WT plants were planted on May 22, 2016 and were grown for 60 days in the green-house. Plants were harvested, tubers were collected, counted and their fresh weight was recorded ( FIG. 8 ). The yield analysis of the StACHT4-2 ⁇ C-OE lines showed 91% increase in the total tuber yield per plant as compared to WT plants. Photographs of representative plants show the increase in biomass accumulation of both shoots and tubers ( FIG. 9 ).
- OE of the potato paralogs StACHT4-2 ⁇ C and StACHT4-1 ⁇ C relieves growth and starch synthesis attenuation, as was found for OE of Arabidopsis AtACHT4 ⁇ C.
- each of the two potato paralogs has a unique function.
- OE expression of StACHT4-2 ⁇ C stimulated the allocation of photosynthates towards growth and near doubles tuber yield and plants shoot growth ( FIGS. 8-9 ), whereas OE expression of StACHT4-1 ⁇ C stimulated transitory starch ( FIG. 10 ).
- OE of the full length protein of either StACHT4-2 ( FIG. 8 ) or StACHT4-1 FIG.

- The present invention provides compositions for attenuating the function of atypical CYS HIS rich thioredoxin 4 (ACHT4), a light-regulated protein expressed in plants and algae that controls starch storage in chloroplast, and methods for increasing plant and algae growth and yield.
- Genetically modified plants with improved agronomic traits such as yield, pest resistance, herbicide tolerance, improved seed compositions, and the like are desired by both farmers and consumers. Although considerable efforts in plant breeding have provided significant gains in desired phenotypes, the ability to introduce specific DNA into plant genomes provides further opportunities for generation of plants with improved and/or unique phenotypes. The ability to develop genetically modified plants with improved traits depends in part on the identification of genes that are useful in recombinant DNA constructs for production of transformed plants with improved properties.

- ACHT4
- The Arabidopsis thaliana atypical cysteine histidine-rich Trxs (ACHTs) constitute a small family of plant-specific and chloroplast-localized Trxs. They are light-regulated and are good catalysts of 2-Cys Prx reduction.
- A recently discovered paralog, AtACHT4, was found by the inventors to attenuate starch synthesis in Arabidopsis thaliana by oxidizing a regulatory disulfide of the AGPase (ADP-glucose pyrophosphorylase, which catalyzes the first committed step in the starch synthesis pathway; Examples 1-2). The oxidizing reaction of AtACHT4 with AGPase requires the C-terminus of AtACHT4 (Example 2).
- Thus, in one embodiment, the present invention provides compositions comprising ACHT4 proteins and nucleic acids and uses thereof. ACHT4 sequences may be from any species comprising such sequences. Table 1 hereinbelow discloses the amino acid sequences of some ACHT4 paralogs in various species, while Table 2 hereinbelow discloses the nucleic acid sequences of some ACHT4 paralogs in various species.

- ACHT4ΔC
- In one embodiment, the present invention provides a recombinant polynucleotide encoding an atypical CYS HIS rich thioredoxin 4 (ACHT4) protein, wherein the C-terminal portion of said ACHT4 protein comprises an inactivating mutation.
- The inventors have demonstrated herein that over-expression (OE) of a C-terminal truncated form of AtACHT4 (AtACHT4ΔC, in which there is a 47 amino acid deletion of the C-terminus) has a dominant negative effect in Arabidopsis plants. AtACHT4ΔC overexpression relieves the oxidation of AGPase and boosts starch synthesis. In contrast, the OE of the full length ACHT4 does not, confirming that the C-terminus of AtACHT4 is indeed required for the attenuation of starch synthesis and the authenticity of the stimulating effect of AtACHT4-C-Del.
- In addition, as demonstrated in Example 2, the stimulation of starch synthesis by AtACHT4-C-Del results in a significant increase in transitory starch content in Arabidopsis leaves and stimulates growth, indicating that AtACHT4ΔC stimulates the export of photosynthates from the chloroplast which are then directed toward plant metabolism and growth.
- There are homologs of the ACHT4 found in Arabidopsis (AtACHT4), and in other species including potato, cassava, maize, rice, barley, wheat, sorghum, rapeseed, castor, bean, cotton, soybean, beet, banana, peppers, chickpea, tomato, oil palm, millet, several species of algae, and other plants and algae (Tables 1-2). As described in Example 3, ACHT4 in potato (paralogs StACHT4-2 and StACHT4-1) is similarly involved in attenuating starch synthesis and growth, and overexpression of the C-terminally deleted forms of StACHT4-1 and StACHT4-2, respectively, disinhibits (i.e. promotes) starch synthesis and nearly doubles tuber yield and plant shoot growth, respectively.
- Since ACHT4 is expressed in all major crop and biofuel species, including rice and corn, attenuation of ACHT4 through dominant negative C-terminal deletions or other means, represents a promising new target for increasing plant growth and yield in all major crop and biofuel species.

- Recombinant Polynucleotides
- In one embodiment, “recombinant polynucleotide” refers to a polynucleotide having a genetically engineered modification introduced through manipulation via mutagenesis, restriction enzymes, and the like. Recombinant polynucleotides may comprise DNA segments obtained from different sources, or DNA segments obtained from the same source, but which have been manipulated to join DNA segments which do not naturally exist in the joined form. A recombinant polynucleotide may exist outside of the cell, for example as a PCR fragment, or integrated into a genome, such as a plant genome.
- The present invention contemplates the use of polynucleotides effective for imparting an enhanced phenotype to genetically modified plants or algae expressing said polynucleotides. Exemplary polynucleotides for use in the present invention are provided herein in Table 2 (SEQ ID NO: 44 through SEQ ID NO: 86). A subset of the nucleic molecules of this invention includes fragments of the disclosed polynucleotides consisting of oligonucleotides of at least 15, preferably at least 16 or 17, more preferably at least 18 or 19, and even more preferably at least 20 or more, consecutive nucleotides. Such oligonucleotides are fragments of the larger molecules having a sequence provided herein in Table 2 (SEQ ID NO: 44 through SEQ ID NO: 86), and find use, for example as probes and primers for detection of the polynucleotides of the present invention.
- Also of interest in the present invention are variants of the polynucleotides provided herein. Such variants may be naturally occurring, including homologous polynucleotides from the same or a different species, or may be non-natural variants, for example polynucleotides synthesized using chemical synthesis methods, or generated using recombinant DNA techniques. Degeneracy of the genetic code provides the possibility to substitute at least one base of the protein encoding sequence of a gene with a different base without causing the amino acid sequence of the polypeptide produced from the gene to be changed. Hence, a polynucleotide useful in the present invention may have any base sequence that has been changed from the sequences in Table 2 (SEQ ID NO: 44 to SEQ ID NO: 86) by substitution in accordance with degeneracy of the genetic code.
- Homologs of the polynucleotides provided herein will generally demonstrate significant identity with the polynucleotides provided herein. A polynucleotide of the present invention is substantially identical to a reference polynucleotide if, when the sequences of the polynucleotides are optimally aligned there is about 60% nucleotide equivalence; more preferably 70%; more preferably 80% equivalence; more preferably 85% equivalence; more preferably 90%; more preferably 95%; and/or more preferably 98% or 99% equivalence over a comparison window. A comparison window is preferably at least 50-100 nucleotides, and more preferably is the entire length of the polynucleotide provided herein. Optimal alignment of sequences for aligning a comparison window may be conducted by algorithms; preferably by computerized implementations of these algorithms (such as the Wisconsin Genetics Software Package). The reference polynucleotide may be a full-length molecule or a portion of a longer molecule. Preferentially, the window of comparison for determining polynucleotide identity of protein encoding sequences is the entire coding region.
- Promoters
- In one embodiment, a polynucleotide of the present invention is operatively linked in a recombinant polynucleotide to a promoter functional in a plant or alga to provide for expression of the polynucleotide in the sense orientation such that a desired polypeptide is produced. Also considered are embodiments wherein a polynucleotide is operatively linked to a promoter functional in a plant to provide for expression of the polynucleotide in the antisense orientation such that a complementary copy of at least a portion of an mRNA native to the target plant host is produced. Such a transcript may contain both sense and antisense regions of a polynucleotide, for example where RNAi methods are used for gene suppression.
- In one embodiment, the promoter of the expression vector of the present invention is operably linked to the polynucleotide. In one embodiment, the promoter is a constitutive promoter. In another embodiment, the promoter is an inducible promoter. In another embodiment, the promoter is a tissue-specific promoter.
- In one embodiment, a promoter used in the compositions and methods of the present invention is cisgenic, i.e. is a promoter that is native to the plant.
- Recombinant polynucleotides of the present invention are assembled in recombinant DNA constructs using methods known to those of ordinary skill in the art. Thus, DNA constructs used for transforming plant cells will comprise a polynucleotide one desires to introduce into a target plant. Such constructs will also typically comprise a promoter operatively linked to said polynucleotide to provide for expression in the target plant. Other construct components may include additional regulatory elements, such as 5′ or 3′ untranslated regions (such as polyadenylation sites), intron regions, and transit or signal peptides.
- Numerous promoters that are active in plant cells have been described in the literature. These include promoters present in plant genomes as well as promoters from other sources, including nopaline synthase (NOS) promoter and octopine synthase (OCS) promoters carried on tumor-inducing plasmids of Agrobacterium tumefaciens, caulimovirus promoters such as the cauliflower mosaic virus or figwort mosaic virus promoters.
- These and numerous other promoters that function in plant cells are known to those skilled in the art and available for use in recombinant polynucleotides of the present invention to provide for expression of desired genes in genetically modified plant cells.
- Furthermore, the promoters may be altered to contain multiple “enhancer sequences” to assist in elevating gene expression. Such enhancers are known in the art. By including an enhancer sequence with such constructs, the expression of the selected protein may be enhanced. These enhancers often are found 5′ to the start of transcription in a promoter that functions in eukaryotic cells, but can often be inserted in the forward or reverse orientation 5′ or 3′ to the coding sequence. In some instances, these 5′ enhancing elements are introns. Deemed to be particularly useful as enhancers are the 5′ introns of the
rice actin 1 andrice actin 2 genes. Examples of other enhancers that can be used in accordance with the invention include elements from the CaMV 35S promoter, octopine synthase genes, the maize alcohol dehydrogenase gene, the maize shrunken 1 gene and promoters from non-plant eukaryotes. - Organ-Specific Promoters
- In other aspects of the invention, expression in plant seed tissues is desired to effect improvements in seed composition. In one embodiment, promoters for use for seed composition modification include promoters from seed genes such as napin,
globulin 1,glutelin 1, and peroxiredoxin antioxidant. - In still other aspects of the invention, preferential expression in plant green tissues is desired. In one embodiment, promoters for expression in plant green tissues include those from genes such as SSU, aldolase and pyruvate orthophosphate dikinase (PPDK).
- Recombinant constructs prepared in accordance with the invention will also in one embodiment, include a 3′ untranslated DNA region that typically contains a polyadenylation sequence following the polynucleotide coding region. Examples of useful 3′ UTRs include those from the nopaline synthase gene of Agrobacterium tumefaciens (nos), a gene encoding the small subunit of a ribulose-1,5-bisphosphate carboxylase-oxygenase (rbcS), and the T7 transcript of Agrobacterium tumefaciens.

In certain embodiments, the host cell utilized in the methods of the present invention is transiently transfected with the nucleic acid molecules of the invention.
- In some embodiments, the host cell utilized in the methods of the present invention is a plant protoplast. Plant protoplasts are plant cells that had their entire plant cell wall enzymatically removed prior to the introduction of the molecule of interest. The complete removal of the cell wall disrupts the connection between cells producing a homogenous suspension of individualized cells which allows more uniform and large scale transfection experiments. This comprises, but is not restricted to protoplast fusion, electroporation, liposome-mediated transfection, and polyethylene glycol-mediated transfection. Protoplast preparation is therefore a very reliable and inexpensive method to produce millions of cells.
- In particular embodiments, the plant protoplast is derived from one of the following genuses: Acorus, Aegilops, Allium, Amborella, Antirrhinum, Apium, Arabidopsis, Arachis, Beta, Betula, Brassica, Capsicum, Ceratopteris, Citrus, Cryptomeria, Cycas, Descurainia, Eschscholzia, Eucalyptus, Glycine, Gossypium, Hedyotis, Helianthus, Hordeum, Ipomoea, Lactuca, Linum, Liriodendron, Lotus, Lupinus, Lycopersicon, Medicago, Mesembryanthemum, Nicotiana, Nuphar, Pennisetum, Persea, Phaseolus, Physcomitrella, Picea, Pinus, Poncirus, Populus, Prunus, Robinia, Rosa, Saccharum, Schedonorus, Secale, Sesamum, Solanum, Sorghum, Stevia, Thellungiella, Theobroma, Triphysaria, Triticum, Vitis, Zea, or Zinnia. In some embodiments, the host cell is derived from a genus that is different from the genus from which the ACTH4 gene is derived.
- Also provided herein are plant cells having the nucleotide sequence constructs of the invention. A further aspect of the present invention provides a method of making such a plant cell involving introduction of a vector including the construct into a plant cell. For integration of the construct into the plant genome, such introduction will be followed by recombination between the vector and the plant cell genome to introduce the sequence of nucleotides into the genome. RNA encoded by the introduced nucleic acid construct may then be transcribed in the cell and descendants thereof, including cells in plants regenerated from transformed material. A gene stably incorporated into the genome of a plant is passed from generation to generation to descendants of the plant, so such descendants should show the desired phenotype.
- Optionally, germ line cells may be used in the methods described herein rather than, or in addition to, somatic cells. The term “germ line cells” refers to cells in the plant organism which can trace their eventual cell lineage to either the male or female reproductive cell of the plant. Other cells, referred to as “somatic cells” are cells which give rise to leaves, roots and vascular elements which, although important to the plant, do not directly give rise to gamete cells. Somatic cells, however, also may be used. With regard to callus and suspension cells which have somatic embryogenesis, many or most of the cells in the culture have the potential capacity to give rise to an adult plant. If the plant originates from single cells or a small number of cells from the embryogenic callus or suspension culture, the cells in the callus and suspension can therefore be referred to as germ cells. In the case of immature embryos which are prepared for treatment by the methods described herein, certain cells in the apical meristem region of the plant have been shown to produce a cell lineage which eventually gives rise to the female and male reproductive organs. With many or most species, the apical meristem is generally regarded as giving rise to the lineage that eventually will give rise to the gamete cells. An example of a non-gamete cell in an embryo would be the first leaf primordia in corn which is destined to give rise only to the first leaf and none of the reproductive structures.

- Homologs of the polypeptides of the present invention may be identified by comparison of the amino acid sequence of the polypeptide to amino acid sequences of polypeptides from the same or different plant sources, e.g. manually or by using known homology-based search algorithms such as those commonly known and referred to as BLAST, FASTA, and Smith-Waterman. As used herein, a homolog is a peptide from the same or a different organism that performs the same biological function as the polypeptide to which it is compared. An orthologous relation between two organisms is not necessarily manifest as a one-to-one correspondence between two genes, because a gene can be duplicated or deleted after organism phylogenetic separation, such as speciation. For a given polypeptide, there may be no ortholog or more than one ortholog. Other complicating factors include alternatively spliced transcripts from the same gene, limited gene identification, redundant copies of the same gene with different sequence lengths or corrected sequence. A local sequence alignment program, e.g. BLAST, can be used to search a database of sequences to find similar sequences, and the summary Expectation value (E-value) used to measure the sequence base similarity.
- A further aspect of the invention comprises functional homolog proteins which differ in one or more amino acids from those of a polypeptide provided herein as the result of one or more of the well-known conservative amino acid substitutions, e.g. valine is a conservative substitute for alanine and threonine is a conservative substitute for serine. Conservative substitutions for an amino acid within the native polypeptide sequence can be selected from other members of a class to which the naturally occurring amino acid belongs. Representative amino acids within these various classes include, but are not limited to: (1) acidic (negatively charged) amino acids such as aspartic acid and glutamic acid; (2) basic (positively charged) amino acids such as arginine, histidine, and lysine; (3) neutral polar amino acids such as glycine, serine, threonine, cysteine, tyrosine, asparagine, and glutamine; and (4) neutral nonpolar (hydrophobic) amino acids such as alanine, leucine, isoleucine, valine, proline, phenylalanine, tryptophan, and methionine. Conserved substitutes for an amino acid within a native amino acid sequence can be selected from other members of the group to which the naturally occurring amino acid belongs. For example, a group of amino acids having aliphatic side chains is glycine, alanine, valine, leucine, and isoleucine; a group of amino acids having aliphatic-hydroxyl side chains is serine and threonine; a group of amino acids having amide-containing side chains is asparagine and glutamine; a group of amino acids having aromatic side chains is phenylalanine, tyrosine, and tryptophan; a group of amino acids having basic side chains is lysine, arginine, and histidine; and a group of amino acids having sulfur-containing side chains is cysteine and methionine. Naturally conservative amino acids substitution groups are: valine-leucine, valine-isoleucine, phenylalanine-tyrosine, lysine-arginine, alanine-valine, aspartic acid-glutamic acid, and asparagine-glutamine. A further aspect of the invention comprises polypeptides that differ in one or more amino acids from those of a described protein sequence as the result of deletion or insertion of one or more amino acids in a native sequence.
- Homologs of the polypeptides provided herein will generally demonstrate significant identity with the polypeptides provided herein. In one embodiment, the present invention provides polypeptides with at least about 50% sequence identity. In one embodiment, the present invention provides polypeptides with at least about 70% sequence identity. In one embodiment, the present invention provides polypeptides with at least about 80% sequence identity with an amino acid sequence of any of the amino acid sequences listed in Table 1. In one embodiment, the present invention provides polypeptides with higher identity to such a polypeptide sequence, e.g. 90% to 99% identity. Identity of protein homologs is determined by optimally aligning the amino acid sequence of a putative protein homolog with a defined amino acid sequence and by calculating the percentage of identical and conservatively substituted amino acids over the window of comparison. Preferentially, the window of comparison for determining identity is the entire polypeptide sequence disclosed herein, e.g. the full sequence of any one of the sequences listed in Table 1.

The recombinant polynucleotide is introduced into the genome to produce genetically modified cells that can be cultured into genetically modified plants having an enhanced phenotype as compared to the parental line or other appropriate control. Such genetically modified cells are cultured into genetically modified plants that produce progeny genetically modified seed. Preferably, multiple genetically modified plants (events) comprising the recombinant polynucleotides are evaluated, e.g. from 2 to 20 or more genetically modified events, to identify a desired enhanced phenotype. Although the design of a recombinant polynucleotide is based on a rational expectation of a phenotypic modification, the present invention also contemplates that unexpected, yet desired enhanced phenotypes may be obtained.
- Genetically modified plants grown from genetically modified seed as described herein will have improved phenotypes that contribute to increased yield or other increased plant value, including, for example, improved seed quality. Of particular interest are plants having altered cell division, enhanced plant growth and development, stress tolerance, including tolerance to abiotic and biotic stress, altered seed or flower development, improved light response, and enhanced carbon and/or nitrogen metabolism, transport or utilization properties.
- Genetic Modification
- In one embodiment, the present invention provides a cisgenic plant. In one embodiment, a cisgenic plant of the present invention is genetically modified, in one embodiment, comprises a second copy of a gene in which a portion of said gene is deleted, but contains no foreign or heterologous genes. In one embodiment, the promoters used in the expression of ACHT4ΔC are cisgenic. In one embodiment, food crops of the present invention are cisgenic.
- In another embodiment, the present invention provides a transgenic plant. In one embodiment, a transgenic plant of the present invention is genetically modified with foreign or heterologous genes. In one embodiment, transgenic plants of the present invention are used for biofuel. In another embodiment, transgenic plants of the present invention are food crop plants.
- Any method or delivery system may be used for the delivery and/or transformation (plant cells)/transfection (algae cells) of the nucleic acid vectors encoding ACHT4 and homologs, paralogs, etc. in the host cell, e.g., plant protoplast. The vectors may be delivered to the host cell either alone, or in combination with other agents. Transient expression systems may also be used. Homologous recombination may also be used.
- Transformation may be accomplished by a wide variety of means, as is known to those of ordinary skill in the art. Such methods include, but are not limited to, Agrobacterium-mediated transformation (e.g., Komari et al., 1998, Curr. Opin. Plant Biol., 1:161), including floral dip transformation, particle bombardment mediated transformation (e.g., Finer et al., 1999, Curr. Top. Microbiol. Immunol., 240:59), protoplast electroporation (e.g., Bates, 1999, Methods Mol. Biol., 111:359), viral infection (e.g., Porta and Lomonossoff, 1996, Mol. Biotechnol. 5:209), microinjection, and liposome injection. Other exemplary delivery systems that can be used to facilitate uptake by a cell of the nucleic acid include calcium phosphate and other chemical mediators of intracellular transport, microinjection compositions, and homologous recombination compositions (e.g., for integrating a gene into a preselected location within the chromosome of the cell). Alternative methods may involve, for example, the use of liposomes, electroporation, or chemicals that increase free (or “naked”) DNA uptake, transformation using viruses or pollen and the use of microprojection. Standard molecular biology techniques are common in the art (e.g., Sambrook et al., 1989, Molecular Cloning: A Laboratory Manual, 2nd ed., Cold Spring Harbor Laboratory Press, New York).
- For the Agrobacterium tumefaciens-based plant transformation system, additional elements present on transformation constructs will, in one embodiment, include T-DNA left and right border sequences to facilitate incorporation of the recombinant polynucleotide into the plant genome.
- In one embodiment, DNA is inserted randomly, i.e. at a non-specific location, in the genome of a target plant line. In another embodiment, DNA insertion is targeted in order to achieve site-specific integration, e.g. to replace an existing gene in the genome, to use an existing promoter in the plant genome, or to insert a recombinant polynucleotide at a predetermined site known to be active for gene expression. Several site specific recombination systems exist which are known to function in plants including cre-lox and FLP-FRT.
- Transformation methods of this invention are preferably practiced in tissue culture on media and in a controlled environment. “Media” refers to the numerous nutrient mixtures that are used to grow cells in vitro, that is, outside of the intact living organism. Recipient cell targets include, but are not limited to, meristem cells, callus, immature embryos and gametic cells such as microspores, pollen, sperm and egg cells. It is contemplated that any cell from which a fertile plant may be regenerated is useful as a recipient cell. Callus may be initiated from tissue sources including, but not limited to, immature embryos, seedling apical meristems, microspores and the like. Cells capable of proliferating as callus are also recipient cells for genetic transformation. Practical transformation methods and materials for making genetically modified plants of this invention, e.g. various media and recipient target cells, transformation of immature embryos and subsequent regeneration of fertile genetically modified plants are known in the art.
- In one embodiment, the method of transformation of algae comprises any of the methods as described hereinabove. In one embodiment, transformation of algae is accomplished using glass bead-assisted transformation, particle gun-mediated (biolistic) transformation, treatment with cellulolytic enzymes to weaken their cell walls, or homologous recombination.
- Markers of Genetic Transformation
- In one embodiment, DNA is introduced into only a small percentage of target cells in any one experiment. Marker genes are used to provide an efficient system for identification of those cells that are stably transformed by receiving and integrating a genetically modified DNA construct into their genomes. Preferred marker genes provide selective markers that confer resistance to a selective agent, such as an antibiotic or herbicide. Potentially transformed cells are exposed to the selective agent. In the population of surviving cells will be those cells where, generally, the resistance-conferring gene has been integrated and expressed at sufficient levels to permit cell survival. Cells may be tested further to confirm stable integration of the exogenous DNA. Useful selective marker genes include those conferring resistance to antibiotics such as kanamycin (nptII), hygromycin B (aph IV) and gentamycin (aac3 and aacC4) or resistance to herbicides such as glufosinate (bar or pat) and glyphosate (EPSPS).
- Screenable markers which provide an ability to visually identify transformants can also be employed, e.g., a gene expressing a colored or fluorescent protein such as a luciferase or green fluorescent protein (GFP) or a gene expressing a beta-glucuronidase or uidA gene (GUS) for which various chromogenic substrates are known. It is also contemplated that combinations of screenable and selectable markers will be useful for identification of transformed cells.
- Cells that survive exposure to the selective agent, or cells that have been scored positive in a screening assay, may be cultured in regeneration media and allowed to mature into plants. Developing plantlets can be transferred to soil less plant growth mix, and hardened off, e.g., in an environmentally controlled chamber at about 85% relative humidity, 600 ppm CO2, and 25-250 microeinsteins m−2s−1 of light, prior to transfer to a greenhouse or growth chamber for maturation. Plants are preferably matured either in a growth chamber or greenhouse. Plants are regenerated from about 6 weeks to 10 months after a transformant is identified, depending on the initial tissue. During regeneration, cells are grown to plants on solid media at about 19 to 28° C. After regenerating plants have reached the stage of shoot and root development, they may be transferred to a greenhouse for further growth and testing. Plants may be pollinated using conventional plant breeding methods known to those of skill in the art and seed produced.
- Progeny may be recovered from transformed plants and tested for expression of the exogenous recombinant polynucleotide. Useful assays include, for example, “molecular biological” assays, such as Southern and Northern blotting and PCR; “biochemical” assays, such as detecting the presence of RNA, e.g. double stranded RNA, or a protein product, e.g., by immunological means (ELISAs and Western blots) or by enzymatic function; plant part assays, such as leaf or root assays; and also, by analyzing the phenotype of the whole regenerated plant.
- One of skill in the art will be able to select an appropriate vector for introducing the encoding nucleic acid sequence in a relatively intact state. Thus, any vector which will produce a host cell, e.g., plant protoplast, carrying the introduced encoding nucleic acid should be sufficient. The selection of the vector, or whether to use a vector, is typically guided by the method of transformation selected.
- Plant Regeneration
- Following transformation, plant cells transformed with a plant expression vector may be regenerated, e.g., from single cells, callus tissue or leaf discs according to standard plant tissue culture techniques. Almost any plant can be entirely regenerated from cells, tissues, and organs of the plant using methods that are known in the art.
- The transformed plants may then be grown, and either pollinated with the same transformed strain or different strains, and the resulting hybrid having expression of the desired phenotypic characteristic identified. Two or more generations may be grown to ensure that expression of the desired phenotypic characteristic is stably maintained and inherited and then seeds harvested to ensure expression of the desired phenotypic characteristic has been achieved.
- Normally, a plant cell is regenerated to obtain a whole plant from the transformation process. The term “growing” or “regeneration” as used herein means growing a whole plant from a plant cell, a group of plant cells, a plant part (including seeds), or a plant piece (e.g., from a protoplast, callus, or tissue part).
- Regeneration from protoplasts varies from species to species of plants, but generally a suspension of protoplasts is first made. In certain species, embryo formation can then be induced from the protoplast suspension. The culture media will generally contain various amino acids and hormones, necessary for growth and regeneration. Examples of hormones utilized include auxins and cytokinins. Efficient regeneration will depend on the medium, on the genotype, and on the history of the culture. If these variables are controlled, regeneration is reproducible. Regeneration also occurs from plant callus, explants, organs or parts.
- In vegetatively propagated crops, the mature genetically modified plants are propagated by utilizing cuttings or tissue culture techniques to produce multiple identical plants. Selection of desirable genetically modified plants is made and new varieties are obtained and propagated vegetatively for commercial use.
- In seed propagated crops, mature genetically modified plants can be self-crossed to produce a homozygous inbred plant. The resulting inbred plant produces seed containing the genetic mutation. These seeds can be grown to produce plants that would produce the selected phenotype, e.g., increased lateral root growth, uptake of nutrients, overall plant growth and/or vegetative or reproductive yields.
- Parts obtained from the regenerated plant, such as flowers, seeds, leaves, branches, fruit, and the like are included in the invention, provided that these parts comprise cells comprising the isolated nucleic acid of the present invention. Progeny and variants, and mutants of the regenerated plants are also included within the scope of the invention, provided that these parts comprise the introduced nucleic acid sequences. Genetically modified plants expressing a selectable marker can be screened for transmission of the nucleic acid of the present invention by, for example, standard immunoblot and DNA detection techniques. Genetically modified plant cells are also typically evaluated on levels of expression of the genetically modified nucleic acid. Expression at the RNA level can be determined initially to identify and quantitate expression-positive plants. Standard techniques for RNA analysis can be employed and include PCR amplification assays using oligonucleotide primers designed to amplify only the genetically modified RNA templates and solution hybridization assays using genetically modified nucleic acid-specific probes. The RNA-positive plants can then analyzed for protein expression by Western immunoblot analysis using the specifically reactive antibodies of the present invention. In addition, in situ hybridization and immunocytochemistry according to standard protocols can be done using genetically modified nucleic acid specific polynucleotide probes and antibodies, respectively, to localize sites of expression within genetically modified tissue. Generally, a number of genetically modified lines are usually screened for the incorporated nucleic acid to identify and select plants with the most appropriate expression profiles.
- In one embodiment, the present invention provides a genetically modified plant that is homozygous for the introduced genetically modified nucleic acid; i.e., a genetically modified plant that contains two added nucleic acid sequences, one gene at the same locus on each chromosome of a chromosome pair. A homozygous genetically modified plant can be obtained by sexually mating (selfing) a heterozygous genetically modified plant that contains a single added genetically modified nucleic acid, germinating some of the seed produced and analyzing the resulting plants produced for altered expression of a polynucleotide of the present invention relative to a control plant (i.e., native, non-genetically modified). Back-crossing to a parental plant and out-crossing with a non-genetically modified plant are also contemplated.
- Transformed plant cells which are derived by any of the above transformation techniques can be cultured to regenerate a whole plant which possesses the transformed genotype. Such regeneration techniques often rely on manipulation of certain phytohormones in a tissue culture growth medium.

- Results
- Reoxidation of ACHT4 by 2-Cys Prx Shortly after Illumination
- In order to examine whether other thylakoid-associated members of the ACHT family have similar or unique roles to that of ACHT1, we analyzed the redox state changes of the ACHT4 catalytic site following the onset of growth light (80 to 100 μE*m−2*s−1) after a typical 16 h night period in plants expressing ACHT4 (Dangoor, 2009). The catalytic site of ACHT4 was found to be mostly disulfide-bonded at the end of the night and to undergo rapid reduction within 1 min of exposure to the light (
FIG. 1A ). As reported for ACHT1, significant oxidation of the ACHT4 catalytic site was observed within 30 min of illumination and counteracted its reductive state. Thereafter, ACHT4 redox state appeared to be in a dynamic quasi-oxidized state. A control experiment demonstrated that the total amount of ACHT4 did not change significantly (FIG. 1A , reduced panel) under the experimental conditions. - To investigate the identity of the proteins that ACHT4 exchanges disulfides with in planta, we captured as in (Dangoor, 2012, The Plant Cell 24(5):1894-1906, which is incorporated herein by reference in its entirety) its intermolecular disulfide reaction intermediates. Protein blot analysis of denatured, but not reduced, plant extracts identified three intermolecular disulfide-linked ACHT4-containing protein complexes, verified by their susceptibility to chemical reduction by dithiothreitol (DTT) (
FIG. 1B , ACHT4 panel). A comparison to the ACHT1 intermolecular disulfide-linked protein complexes (FIG. 1B , ACHT1 panel) showed that two of the main ACHT4 complexes, with estimated sizes of ˜55 kDa and ˜70 kDa, corresponded to the combined molecular weight of the previously characterized heterodimeric and the heterotrimeric ACHT1 and 2-Cys Prx complexes, respectively (Dangoor, 2012). Interestingly, an additional third intermolecular disulfide ACHT4 complex (marked with asterisk), with a higher molecular weight than that of the ACHT4 2-Cys Prx heterotrimer, and which did not form in ACHT1 extracts, was identified as well. - To verify the authenticity of ACHT4-2-Cys Prx intermolecular disulfide complexes, they were pulled down in a reciprocal analysis performed under non-reducing denaturing conditions, with either anti-HA (for ACHT4) or anti-2-Cys Prx sera. Protein blot analysis of denatured and reduced samples identified the 2-Cys Prx in the anti-HA pulled down complexes and ACHT4 in the anti-2-Cys Prx pulled down complexes (
FIG. 1C ). As expected, mass-spectrometry analysis identified both ACHT4 and 2-Cys Prx in the gel slice containing the heterotrimer complex but not in a corresponding gel slice containing extracts that were separated under reducing conditions (Table 3). We concluded that ACHT4 exchanged disulfides with the 2-Cys Prx in plants, in a similar manner as that reported for ACHT1. - APS1 is a Unique Target of ACHT4
- The comparison of the intermolecular disulfide complexes formed in planta by ACHT4 and ACHT1 uncovered a major disulfide linked complex unique to ACHT4 (
FIG. 1B ). A mass spectrometry analysis identified APS1 in the gel slice containing the unique complex of ACHT4 but not in a corresponding reduced gel slice (Table 3). To verify these findings, the protein intermolecular disulfide complexes were reciprocally pulled-down under non-reducing denaturing conditions with either anti-HA, for ACHT4, or anti-APS1. Protein blot analyses identified the APS1 in the anti-HA pulled down complexes and ACHT4 in the anti-APS1 pulled down complexes (FIG. 1D ), suggesting that APS1 is a target protein of ACHT4. These findings also implied that although ACHT1 and ACHT4 share a similar mode of oxidation by 2-Cys Prx, they differ in at least one major target, suggesting that they may serve to regulate distinctive processes. - ACHT4 Participates in the Diurnal Redox Regulation of AGPase
- The trapping in vivo of APS1-ACHT4 and 2-Cys Prx-ACHT4 disulfide exchange reaction intermediates (RIs) opened the possibility of studying the environmental stimuli that influence ACHT4-driven AGPase redox control. First, we analyzed the changes in the 2-Cys Prx-ACHT4 and APS1-ACHT4 RIs, and the corresponding changes in the APS1 redox state upon light onset of plants grown under a 8/16 h light/dark regime. Intriguingly, the low APS1-ACHT4 RI level and the high 2-Cys Prx-ACHT4 level in the dark contrasted each other (
FIG. 2A ). Since the 2-Cys Prx RIs were high in the dark also with ACHT1 (Dangoor, 2012), it suggested that the ACHT4 disulfide transfer reaction with APS1 differs from the reducing reaction of either ACHT1 or ACHT4 with 2-Cys Prx (Dangoor, 2009). As the dark is a relatively stable condition, i.e. changes in redox state of reacting proteins are not expected, these finding could conceivably reflect an opposite directionality of the disulfide transfer reaction, ACHT4 to APS1 versus 2-Cys Prx to ACHT4, which could possibly be derived from dissimilar redox midpoint potentials of the proteins. Consequently, the contrasting levels of ACHT4 RIs in the dark would be a result of the levels of its two substrates, high level of oxidized 2-Cys Prx and low level of reduced APS1. Notably, the increase in the level of APS1-ACHT4 RIs upon illumination (FIG. 2A ) matched the increase in reduction of APS1 at this time period, further supporting this notion. The APS1-ACHT4 RI level approached steady state level after a 30 min transition period in the light. The 2-Cys Prx-ACHT4 RI levels (FIG. 2A ) showed a similar pattern to those of 2-Cys Prx-ACHT1 (Dangoor, 2012) also during illumination, a transient decrease, then an increased level, which reached a steady state after the 30 min transition period in the light. - The analysis of the concomitant changes in the redox state of APS1 showed that APS1 was resting in the inactive intermolecular disulfide form in the dark (
FIG. 2B ). In addition, in dark conditions, a monomeric form of APS1 with slightly lower molecular weight (MW) that was converted to the monomeric form with the expected MW during the first 5 min of illumination was observed. The conversion of the faster migrating form to the slower form upon illumination, suggested that the lower MW monomer could be a compacted APS1 form bearing an intramolecular disulfide, the reduction of which creates a stretched molecule in the light. To verify that, we compared the migration of the APS1 monomer purified from dark protein extracts and chemically reduced, with DTT, in vitro, to the monomer purified from light extracts (FIG. 2C ). The DTT-reduced monomer derived from dark extracts migrated parallel to the monomer from light extract, whereas the DTT-reduced monomer isolated from light extracts did not alter its migration, indicating that an APS1 intramolecular disulfide indeed participated in the redox control of APS1. Thus, we analyzed the monomeric APS1 via a methodology that exclusively measures the levels of reduced monomer. In this method, the reduced cysteines are first blocked with N-ethyl maleimide (NEM), and the disulfides are then chemically reduced and reacted with methoxypolyethylene glycol-maleimide (mPEG). We found that the level of reduced monomer was barely detectable in the dark, gradually increased during the 30 min transition period and reached a steady state level thereafter (FIG. 2D ). In parallel, 2-Cys Prx-ACHT4 RI levels, indicative of ACHT4 oxidative signal, were low during the transition period and also reached relatively stable values only thereafter (FIG. 2A ), suggesting that the oxidative signal of ACHT4 dynamically counteracted APS1 reduction by Trx-f1, and approached a dynamic equilibrium after 30 min in the light. - Both 2-Cys Prx ACHT4 and APS1 RI levels and APS1 redox state after the light was switched off, i.e. the period in which oxidation is expected to turn off AGPase, were inverse to those observed after the onset of light. The 2-Cys Prx-ACHT4 RI remained stable during the first 5 min and then increased, suggesting increased oxidation by 2-Cys Prx during that time period (
FIG. 2E ). Levels of the reduced monomeric APS1 form gradually decreased alongside a concomitant increase in the oxidized, intramolecular disulfide-bearing monomer and intermolecular disulfide-linked dimer (FIG. 2F ). At the same time, the level of the APS1 reaction intermediate, which was high at the end of the day, gradually decreased and reached levels similar to those observed before the beginning of the day (FIG. 2E ). These results are consistent with an increased oxidation rate of APS1 by ACHT4 during the transition from day to night, resulting in diminishing APS1 activity. - ACHT4 Participates in the Regulation of APS1 During Fluctuations in Light Intensity
- We found that ACHT4 participated in the diurnal regulation of APS1, that has been proposed to influence the day and night cycles of starch synthesis and degradation. The reactions of ACHT4 with APS1 and 2-Cys Prx, as judged by the levels of their disulfide exchange reaction intermediates, seemed to reach balanced levels after a transition period in the light (
FIG. 2A ), as manifested by APS1 activation levels (FIG. 2B ), suggesting that ACHT4 oxidation of APS1 is active and dynamically counteracting its reduction by Trx-f1 during the day. Such activity might be important for the rationing of photosynthates to starch and sugars exported from the chloroplast during the day. Alternatively, as shown in the unicellular green alga Chlamydomonas reinhardtii, such activity may regulate the levels of starch to be used as a transient pool for reduced carbon in a fluctuating light environment. We tested this hypothesis by subjecting the plants to small fluctuations of light intensity during the day. Interestingly, when light intensity was reduced to 10 μE*m−2*s−1 after a 2-hour 50 μE*m−2*s−1 light regime, APS1-ACHT4 RI levels declined within 5 min, and rose again when the light intensity was switched back to 50 μE*m−2*s−1 (FIG. 3A ). While 2-Cys Prx-ACHT4 RI levels remained steady upon decreased light intensity, they rapidly declined following the transfer back to the higher light intensity (FIG. 3A ). In parallel, a lower ratio of reduced to oxidized APS1 was obtained following the transfer to the lower light and a higher ratio was observed upon increased light intensity (FIG. 3B ). These results suggest that, in addition to its diurnal role of ACHT4-driven oxidation of APS1 in the beginning of the night, it may also participate in the dynamic regulation of AGPase activity in response to natural fluctuations in light intensity. Furthermore, the reduction of APS1 upon increased light intensity occurred rapidly in comparison to its oxidation upon decreased light intensity (FIG. 3B ), suggesting that AGPase redox regulation might also play a role in stimulating a transient burst of starch synthesis to accommodate an abruptly increased light intensity. The concomitant gradual decrease of both APS1-ACHT4 RIs levels and reduced APS1 upon lowering the light intensity and the abrupt increase in both upon increased intensity further supported the notion that ACHT4 reacted with the reduced APS1. - The C-terminus of ACHT4 is important for its reaction with APS1
- We then assessed whether the distinct 47-amino acid-long ACHT4 C-terminus (
FIG. 4A ) is responsible for its in planta differences from ACHT1, by analyzing the 2-Cys Prx and APS1 RIs in plants expressing ACHT4 lacking the C-terminus (ACHT4ΔC). Notably, the ACHT4ΔC form reacted with 2-Cys Prx, and formed the two intermolecular disulfide-linked 2-Cys Prx ACHT4 RIs, but failed altogether to interact with APS1 (FIG. 2B ). The preferential reaction of ACHT4ΔC with the 2-Cys Prx and not with APS1 was maintained throughout the transition from night to day (FIG. 4C ). Moreover, the profile of the reaction of ACHT4ΔC with 2-Cys Prx during the first 2 hr of illumination was similar to that of ACHT4, indicating that the oxidation of ACHT4ΔC by 2-Cys Prx does not involve the protein's C-terminus and that the C-terminus deletion only affected ACHT4-driven redox control of APS1. - Both ACHT4 and ACHT1 are thylakoid-associated proteins. The distinct reaction of ACHT4, and not of ACHT1, with APS1, prompted us to investigate whether the disparity might be due to different thylakoid localization, either the grana, the grana margins, or the stroma lamella. Protein blot analysis showed that ACHT1 was primarily found in both the grana and the stroma lamella domains, whereas ACHT4 was mainly present in the stroma lamella domain and was undetectable in the grana (
FIG. 4D ), further promoting distinct roles of ACHT4 and ACHT1. The membrane association of ACHT4ΔC was then analyzed to determine whether ACHT4 localization is influenced by its unique C-terminus. Only a small increase in the partitioning of ACHT4ΔC to the grana margins was observed, suggesting that the ACHT4 C-terminus deletion effect on its disulfide exchange reaction with APS1 was direct and not mediated via its thylakoid domain localization. - The finding that the deletion of the ACHT4 C-terminus diminished its disulfide exchange reaction with APS1 (
FIG. 2B ) facilitated studying the effect of ACHT4 on APS1 redox state and on transitory starch content. We first compared the APS1 redox state after two hours in the light, representing steady state conditions in which transitory starch is synthesized, and when light intensity was reduced, conditions in which APS1 is being oxidized (FIG. 3 ). Consistently with the expected oxidative role of ACHT4 and the dominant negative effect of the C-terminus deletion, plants expressing increased levels of ACHT4 exhibited lower levels of reduced APS1 monomer, and plants expressing ACHT4ΔC contained higher levels of the reduced APS1 monomer, than WT plants (FIG. 5A ). Next, in order to determine whether the influence of ACHT4 on the redox state of APS1 impacts starch accumulation, we assayed the starch content of WT ACHT4 and ACHT4ΔC plants at the end of the day (FIG. 5B ). In agreement with the changes in the APS1 redox state, plants expressing ACHT4 showed reduced starch levels, whereas plants expressing ACHT4ΔC contained increased starch levels. These results corroborate the notion that disulfides transferred by ACHT4 to APS1 are used in planta to fine-tune APS1 activity by counterbalancing the reduction of APS1 by the reductive type Trxs. - Expression of AtACHT4ΔC Also Increases Arabidopsis Biomass by 10%
- Stimulation of starch synthesis results not only in increased accumulation of transitory starch in Arabidopsis leaves, it also stimulates growth, indicating that OE of AtACHT4ΔC stimulates the export of photosynthates from the chloroplast which are then directed toward growth and biomass accumulation.
- AtACHT4ΔC-OE, AtACHT4-OE and WT lines were grown under long day (18 h/6 h of light/dark cycle at 21° C./18° C.) for 4 weeks. The plants shoot was excised and fresh weight (FW) were recorded. The tissues were dried at 60° C. for 4 days and dry weight (DW) were recorded. The FW of AtACHT4ΔC-OE plants was increased by 10.6% (
FIG. 6A ) and the DW was increased by 9.1% over those of WT (FIG. 6B ), indicating that AtACHT4ΔC stimulates the export of photosynthates from the chloroplast which are then directed toward growth. The FW of AtACHT4 OE plants was decreased by 10.9% (FIG. 6A ) and the DW was increased by 11.5% over those of WT (FIG. 6B ), confirming that the C-terminus of ACHT4 attenuates growth. - Potato Plants
- Arabidopsis has one paralog of ACHT4 where other crop plants, including potato, maize, rice, barley, wheat, sorghum, castor, bean, rapeseed, cotton, soybean, beat, banana, chili, chickpea, tomato, African oilpalm, Foxtail millet, cassava and the algae Chlamydomonas and Chlorella have one to five paralogs (
FIG. 7 ). - Materials and Methods
- Identification and Over Expression of AtACHT Homologs in Potato
- We analyzed the potato genome for AtACHT4 homologs. Protein blast (blastP) analysis of AtACHT against the genome database of potato (solgenomics.net) identified two paralogs, StACHT4-1 (XP_006348023.1) and StACHT4-2 (XP_006351368.1). A 69 and 68 amino acid long tail region at the C-terminus of StACHT4-1 and StACHT4-2, correspondingly, were identified. Four constructs of StACHT4-1ΔC and StACHT4-2ΔC, StACHT4-1, and StACHT4-2 were custom synthesized by Hy-Laboratories Ltd., Israel, were subcloned into pART7 vector under control of CaMV35S promoter and OCS terminator. HA (Human influenza hemagglutinin) tag was fused in frame at the C-terminus of each of the protein coding sequences. All four StACHT4::pART7 and StACHT4-2ΔC:: pART7 constructs were digested with NotI and subcloned into pART27 plant expression vector (
FIG. 11 ) and used to transform potato leaf discs (Solanum tuberosum cv. Desiree) using a standard agrobacterium-based transformation protocol. Positive transformants were identified by PCR analysis and protein expression was verified by immunoblot analysis using anti-HA antibody. - Results
- The Over Expression of StACHT4-2ΔC in Potato Plants Nearly Doubles the Tubers Yield in Comparison to WT Plants
- The StACHT4-2ΔC-OE and WT plants (Solanum tuberosum cv. Desiree) were planted on May 22, 2016 and were grown for 60 days in the green-house. Plants were harvested, tubers were collected, counted and their fresh weight was recorded (
FIG. 8 ). The yield analysis of the StACHT4-2ΔC-OE lines showed 91% increase in the total tuber yield per plant as compared to WT plants. Photographs of representative plants show the increase in biomass accumulation of both shoots and tubers (FIG. 9 ). - StACHT4-1ΔC OE Lines Accumulated Increased Level of Transitory Starch in Leaves
- To test whether StACHT4-1ΔC OE proteins regulate transitory starch content, young green leaves from 6-weeks old green-house grown plant were collected and analyzed for the starch content by Sigma starch assay kit (Catalog Number SA20) with some modifications. Approximately, 0.25-0.5 g fresh leaves were ground to fine powder using liquid nitrogen and then suspended into 20 ml DMSO and 5 ml of 8M HCl solution. The suspensions were incubated for 30 min at 60° C. and then 50 ml water was added to it. The pH was adjusted between 4 and 5, allowed to cool and volume adjusted till 100 ml. From these samples 400 μl were mixed with same volume of starch assay reagent, incubated for 15 min at 60° C. and then allowed to cool at room temperature. Then 200 μl of starch assay mixture were mixed with same volume of glucose assay reagent, incubated at room temperature for 15 min and then absorbance was recorded at 340 nm. Simultaneously, standard starch powder (provided in kit) at concentration of 0, 2, 4, 6, 8 and 10 mg were also used for starch assay and a standard curve was plotted using the absorbance data. The absorbance recorded from the leaves sample of potato transgenic lines were then used to calculate the starch level in leaves using formula obtained from the standard curve. Notably, the StACHT4-1ΔC OE lines accumulated 19% higher starch content relative to WT plants (
FIG. 10 ). - OE of the potato paralogs StACHT4-2ΔC and StACHT4-1ΔC relieves growth and starch synthesis attenuation, as was found for OE of Arabidopsis AtACHT4ΔC. However, in potato, each of the two potato paralogs has a unique function. OE expression of StACHT4-2ΔC stimulated the allocation of photosynthates towards growth and near doubles tuber yield and plants shoot growth (
FIGS. 8-9 ), whereas OE expression of StACHT4-1ΔC stimulated transitory starch (FIG. 10 ). Importantly, OE of the full length protein of either StACHT4-2 (FIG. 8 ) or StACHT4-1 (FIG. 10 ) did not result in the stimulating effect, again demonstrating that the expressed C-terminus truncated form of ACHT4 has a negative dominant effect, in StACHT4-2ΔC or StACHT4-1-ΔC, as well as in AtACHT4ΔC. - It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof.
