Information And Results
Project Summary

The program is a basic research project to develop potentially new tools and knowledge pertinent to all breeders and geneticists. Program seeks to gain new understanding of gene expression that could, in turn impact all areas of variety development including compositional traits, which have long term market opportunity effects. Program also seeks to discover role of cis-regulatory DNA elements, that basically act on top of genetic elements, currently understood to regulate gene expression i.e. promoters. Development of tools that positively affect promoters may in turn positively affect gene expression – in a way currently not possible.

September 15, 2020 Report
Gene expression is typically understood to be controlled by their promoters. What controls promoter function is less understood, thus limiting the ability to modify gene expression in plants to obtain desired changes. The discovery of cis-regulatory DNA elements is starting to change our approach to this challenge. These are DNA sequences elsewhere in the genome that affect the ability of promoters to control genes and their expression. We are using newly developed genomic methods to systematically and precisely identify, analyze, and validate cis-regulatory DNA elements important for soybean seed development, including the synthesis and accumulation of oil and protein and their precursors. Thus far, we have produced the data required to identify the location of these critical cis-regulatory elements. Our next steps will be to specifically identify those associated with key genes important for protein and oil production in the seed and to initiate gene editing of these sequences. These edited sequences will produce plants with more or less gene expression and potentially expand the tissues and organs in which the genes are expressed. We cannot at this time predict which of these events will occur, but what we can do is select plants with desired alterations to protein or oil production.

Benefit To Soybean Farmers

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.
