Abstract
The present invention is directed to plants that display a pathogen resistance phenotype due to altered expression of a PPR2 nucleic acid. The invention is further directed to methods of generating plants with a pathogen resistance phenotype.
Claims13
A method of producing a plant having increased pathogen resistance, said method comprising:
- a) introducing into cells of the plant a plant transformation vector comprising a nucleotide sequence that encodes a Myb polypeptide that confers Peronospora parasitica resistance (PPR2), said Myb polypeptide selected from the group consisting of:
- the polypeptide sequence of SEQ ID NO:2;
- a polypeptide sequence having at least 95% sequence identity to SEQ ID NO:2;
- and an Arabidopsis thaliana polypeptide having at least 85% sequence identity to SEQ ID NO:2, and
- b) growing the transformed cells to produce a transgenic plant, wherein said nucleotide sequence is expressed, and said transgenic plant exhibits increased pathogen resistance relative to a control plant.

A method of producing a plant having increased pathogen resistance, said method comprising:
- a) introducing into cells of the plant a plant transformation vector comprising a nucleotide sequence that encodes or is complementary to a sequence that encodes Peronospora parasitica resistance polypeptide comprising the amino acid sequence of SEQ ID NO:
- 2, SEQ ID NO:
- 11, or SEQ ID NO:
- 12;
- and
- b) growing the transformed cells to produce a transgenic plant, wherein said nucleotide sequence is expressed, and said transgenic plant exhibits increased pathogen resistance relative to a control plant.
