This project is novel in that a unique population of P. sojae is used to extend the current state of knowledge of genetic changes that occur in Avr genes that enable them to cause disease on P. sojae- resistant cultivars and the impact of Rps genes on Avr gene evolution. The short-term goal is to improve understanding of Avr gene evolution. The long-term goal is to reduce losses to P. sojae through an improved understanding of the Rps-Avr interaction. It characterizes avirulence genes in isolates of P. sojae collected from the soybean cultivar rotation microplot study and determine changes in avirulence genes in P. sojae under controlled conditions.
Key Benefactors:
