Brief Project Summary:

Improve soybean nodulation by beneficial rhizobacteria and thereby improve the nitrogen-fixing ability of desirable soybean cultivars. Our research has identified four candidate genes that regulate specificity in soybean-rhizobacteria interactions. Silencing either of these genes (two glycerol-3-phosphate dehydrogenase isoforms, LY1a, b, and two membrane-associated proteins NDR1 & LEA) promotes soybean nodulation by incompatible strains of rhizobacteria. In the past year, we generated constructs for RNAi-mediated silencing of the two GLY1 genes and submitted them to the University of Missouri-Columbia plant transformation facility for transfer into soybean. The goal is to generate stable...

Information And Results
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.
