1. 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.
