Brief Project Summary:

This project continues efforts to use virus-induced gene silencing (VIGS) to characterize resistance genes that promise to protect soybean against damages caused by soybean aphid and water rot. Research plans to develop a new virus-induced gene silencing vector for examining soybean genes responsible for resistance to the water rot pathogen Phytophthora sojae, continue to interrogate soybean genes responsible for resistance to soybean aphid and ccreen soybean aphid genes for the ones most sensitive to RNAi repression using a virus-based method.

Key Benefactors:
farmers, agronomists, extension agents, soybean breeders, seed companies

Information And Results
Project Deliverables

1. Successful completion of the Objective #1 will identify the Rps8 gene responsible for resistance to P. sojae, and lay the foundation for characterization of additional resistance loci.
2. Completion of the second objective will identify the true Rag5 gene, and accelerate the breeding of this R gene to other soybean varieties, leading to increased yield of soybean production.
3. Completion of the third objective is expected to provide candidate aphid genes that can be targeted by transgenically expressed RNAi, leading to lasting control of soybean aphid infestation.

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.
