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 comprising
- identifying a plant that has an allele in a nucleotide sequence that encodes a Myb polypeptide that confers Peronospora parasitica resistance (PPR2) and that results in increased pathogen resistance compared to plants lacking the allele;
- and
- generating progeny of the identified plant,
- wherein the Myb polypeptide is 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 wherein the generated progeny inherit the allele and have the increased pathogen resistance.
