The goal of this project involves identifying and isolating genes, or germplasm, from cultivated and wild soybean that can be used to improve yield, seed quality, pest resistance and energy, nutrient and water use efficiency in soybean plants. This article, and others in a series entitled South Dakota Soybean Checkoff Research, will identify and briefly describe some of the research projects funded by checkoff dollars that are conducted by South Dakota State University.

The project provides for innovative approaches to solve practical problems facing soybean producers in South Dakota. Some of the objectives include: Isolating major QTLs alleles and germplasm from wild soybeans (G. soja) to improve commercial varieties for resistance to biotic (soybean aphids) and abiotic (iron deficiency chlorosis) stresses; Isolating transcription factors that can be used by industry to improve soybean drought stress; Identifying functional drought-tolerant genes in soybeans through proteomics analyses of recombinant inbred lines; Studying the drought-signaling pathway in soybeans by induction and characterization of mutants; Identifying new genes for soybean cyst nematode resistance and soybean oil composition, and; Mapping and isolating new genes for soybean aphid resistance; and Developing novel techniques for investigating and exploitation of genes.
This project is funded by South Dakota Soybean Research and Promotion Council
