Brief Project Summary:

This project continues research that focuses on soybean plants with increased root length and branching to boost yield and resiliency of yield. A strong root system maximizes plant nutrition, defense and water use. Soybean plants with increased root length and branching can significantly improve water/nutrient uptake efficiency and yield potential in diverse environments. This “root genes" project focuses on the underground to make a better soybean crop, and more of it, aboveground. To do this, work aims to produce stable transgenic soybean plants overexpressing novel soybean root genes and evaluate them for impact on root growth and promoting tolerance to drought and nutrient deficiency.

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

Information And Results
Project Deliverables

We expect that the discovery of the novel root-important genes identified in our research will lead to the production of soybean with deeper and more extensive root systems. In turn, these plants will have improved performance and yield, particularly under conditions of limited water and nutrient availability. These outcomes may be accomplished with or without being regulated as a GMO, depending on the gene and its effect. The present study provides a basis for development of soybean lines with improved growth and tolerance to abiotic stresses.

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.
