Our approach will identify candidate Phytophthora sojae resistance genes for Rps2, Rps3 and Rps8. We will leverage the Williams82 and PI 96983 genome sequences and use it to identify candidate genes from the resistant parents. Our approach will be to compare sequence from the Williams82 soybean genome and sequence from PI96983, which does not have an Rps gene in these regions, to sequence from lines with Rps2, Rps3 and Rps8. Real-time PCR will be used to monitor expression of candidate genes in resistant and susceptible parents following P. sojae infection. The function of expressed candidate resistance genes will be assayed using virus induced gene silencing to "turn off" resistance.
