Brief Project Summary:

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:
farmers, agronomists, Extension agent, soybean breeders, seed companies

Information And Results
Project Deliverables

Research and extension presentations and publications (scientific papers, newsletter articles, blogs, tweets) summarizing the project progress and documenting new information that will expand the knowledge of producers, industry and researchers regarding Phytophthora root rot of soybeans.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
