Phytophthora root rot is primarily managed by planting varieties with genes that confer resistance. Fourteen Rps genes have been identified and four genes are currently used in commercial soybean varieties to provide resistance to the disease. The effectiveness of a resistance gene relies on its ability to recognize the pathogen's corresponding avirulence gene. The goal of this project is to characterize the genetic changes that occur within the avirulence gene(s) of P. sojae that enable the pathogen to escape detection by the corresponding resistance gene.
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.
