Brief Project Summary:

This project was funded by the KSPB grant program in 2019-2020, which allowed us to obtain exciting data related to the use of the biocontrol agent Trichoderma in regulating soybean growth and development as well as response to biotic and abiotic stresses. Our work has identified plant produced chemicals that can provide pathogen resistance and abiotic tolerance in soybean. In addition, we showed that Trichoderma positively regulates Rhizobia-mediated nitrogen fixation. A patent application involving the use of a recently discovered RNA molecule to improve biotic resistance has been filed. Funding is requested for an additional year to complete the field trials using Trichoderma and to develop...

Final Project Results

The overall goal of this research project is to increase profitability of soybean production by
simultaneously enhancing yield as well as tolerance against biotic and abiotic stresses. Our
results show that in soybean, the growth benefits of Trichoderma koningiopsis(T-51) infection
function additively with those of nitrogen-fixing bacteria. Additionally, T-51 infection
enhances nodulation in soybean and induces foliar (systemic) disease resistance in soybean,
Arabidopsis, tobacco and tomato. This is similar to the foliar disease resistance induced by
root exposure to incompatible rhizobia in soybean. We further show that the signaling
pathways activated in response to T-51 and incompatible rhizobia overlap significantly with
pathogen induced systemic immunity.

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.
