Abstract
The present invention is directed to plants that display a pathogen resistance and increased drought tolerance phenotype due to altered expression of a PRDT1 nucleic acid. The invention is further directed to methods of generating plants with a pathogen resistance and increased drought tolerance phenotype.
Claims10
A transgenic plant comprising a plant transformation vector comprising a nucleotide sequence that encodes a PRDT1 polypeptide selected from the group consisting of:
- the amino acid sequence of SEQ ID NO:
- 11, an amino acid sequence having at least 95% sequence identity to SEQ ID NO:
- 11, and an Arabidopsis thaliana polypeptide having at least 95% sequence identity to SEQ ID NO:
- 11, wherein said transgenic plant has increased drought tolerance relative to control plants.
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 PRDT1 polypeptide, said polypeptide selected from the group consisting of:
- the amino acid sequence of SEQ ID NO:
- 11, an amino acid sequence having at least 95% sequence identity to SEQ ID NO:
- 11, and an Arabidopsis thaliana polypeptide having at least 95% sequence identity to SEQ ID NO:
- 11, and
- b) growing the transformed progenitor cells to produce a transgenic plant, wherein said polynucleotide sequence is expressed, and said transgenic plant exhibits increased drought tolerance relative to control plants.
