Abstract
The invention relates to plant transcription factor polypeptides, polynucleotides that encode them, homologs from a variety of plant species, and methods of using the polynucleotides and polypeptides to produce transgenic plants having advantageous properties, tolerance low nitrogen, cold and water deficit conditions, and resistance to disease, as compared to wild-type or other control plants.
Claims20
A nucleic acid construct comprising a recombinant nucleic acid sequence encoding a polypeptide that regulates transcription in a plant, wherein the polypeptide has an AP2 domain with at least 83% amino acid identity to amino acids 6-70 of SEQ ID NO:
- 18, the polypeptide comprises an EDLL domain of SEQ ID NO:
- 63, and expression of the polypeptide in a plant confers greater tolerance to water deficit or nitrogen-limited conditions than a control plant.
A transformed plant that has greater tolerance to nitrogen-limited conditions than a control plant;
- wherein the transformed plant is transformed with a nucleic acid construct comprising a recombinant polynucleotide encoding a polypeptide;
- wherein the polypeptide has an AP2 domain with at least 83% amino acid identity to amino acids 6-70 of SEQ ID NO:
- 18, the polypeptide comprises an EDLL domain of SEQ ID NO:
- 63, and expression of the polypeptide in the transgenic plant confers to the transgenic plant greater tolerance to nitrogen-limited conditions than the tolerance to nitrogen-limited conditions of the control plant.
A transformed plant that has greater tolerance to water deficit than a control plant;
- wherein the transformed plant is transformed with a nucleic acid construct comprising a recombinant polynucleotide encoding a polypeptide;
- wherein the polypeptide has an AP2 domain with at least 83% amino acid identity to amino acids 6-70 of SEQ ID NO:
- 18, the polypeptide comprises an EDLL domain of SEQ ID NO:
- 63, and expression of the polypeptide in the transgenic plant confers to the transgenic plant greater tolerance to water deficit than the control plant.
