Abstract

The present invention is directed to plants that display a pathogen resistance phenotype due to altered expression of a PPR1 nucleic acid. The invention is further directed to methods of generating plants with a pathogen resistance phenotype.

Claims (3)

1. A method of generating a plant having an increased pathogen resistance phenotype comprising identifying a plant that has a PPR1 gene allele that encodes a PPR1 polypeptide having a sequence at least 95% identical to SEQ ID NO:3 that results in increased pathogen resistance to Peronospora parasitica compared to plants lacking the allele and generating progeny of said identified plant, wherein the generated progeny inherit the allele and have the increased pathogen resistance phenotype.

2. The method of claim 1 that employs candidate gene/QTL methodology.

3. The method of claim 1 that employs TILLING methodology.
