Generation of plants with improved drought tolerance
View Patent ↗The present invention is directed to plants that display a drought tolerance phenotype due to altered expression of a DR05 nucleic acid. The invention is further directed to methods of generating plants with a drought tolerance phenotype.
1. A transgenic plant comprising a plant transformation vector comprising a nucleotide sequence that encodes a DRO5 polypeptide comprising an amino acid sequence having at least 90% sequence identity to the amino acid sequence of SEQ ID NO:2, wherein said transgenic plant has increased drought tolerance relative to a control plant.
2. The transgenic plant of claim 1 wherein the transformation vector comprises a constitutive promoter that controls expression of the DRO5 polypeptide.
3. A plant part obtained from the plant of claim 1 , and comprising said plant transformation vector.
4. A seed obtained from the plant of claim 1 and comprising said slant transformation vector.
5. A method of producing increased drought tolerance in a plant, said method comprising:
(a) introducing into progenitor cells of the plant a plant transformation vector comprising a nucleotide sequence that encodes a DRO5 polypeptide comprising an amino acid sequence having at least 90% sequence identity to the amino acid sequence of SEQ ID NO:2, thereby producing transformed progenitor cells and
(b) growing the transformed progenitor cells to produce cells to produce a transgenic plant, wherein said nucleotide sequence is expressed, and said transgenic plant exhibits increased drought tolerance relative to a control plant.
6. A plant obtained by the method of claim 5 .
7. A plant cell obtained from the plant of claim 1 , and comprising said plant transformation vector.
