Final Project Results

Updated December 10, 2019:
The research team made progress on multiple fronts in our identification and manipulation of plant traits that control soybean resistance to soybean cyst nematode.
Highlights include:
• Soybean germplasm development and characterization for both naturally occurring and transgenically developed new versions of the Rhg1 locus, which plays a major role in SCN resistance.
• Two scientific papers published in peer-reviewed journals, one reporting early gene expression responses of soybean to soybean cyst nematode HG type 0, and the other reporting the unexpected and usefully predictive presence of a "copia retrotransposon" (mobile DNA element) within one of the Peking-type Rhg1 genes.
• Two additional scientific manuscripts submitted to peer-reviewed journals, reporting that the gamma-SNAP encoded at cqSCN-006 contributes to SCN resistance, and reporting syntaxins that contribute to SCN resistance.
• Additional proteins identified by the research team that are contributors to SCN resistance.
• Achievement of new focus on a smaller set of candidate genes that are the likely cause of the SCN resistance trait conferred by the cqSCN-007 quantitative trait locus.
• Development and initial use of Rhg1 locus DNA methylation assays to assess the potential contribution of differential Rhg1 locus methylation to SCN resistance.

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.
