Unit: College of Agricultural Sciences, Dept. of Animal Sciences, Food and Nutrition, and Dept. of Plant, Soil, and General Agriculture
Brief Description:
This invention involves utilization of gene molecular markers to detect trait loci (QTL) and cloning the genes to control the production of glycitein, genistein, and daidzein. These phytoestrogens (estrogenic isoflavones) display physiologic effects in animals and humans. This invention can provide for a significant increase in beneficial phytoestrogens in soybeans while reducing unwanted phytoestrogens.
Patent Status:
Provisional patent filed.
Potential Commercial Uses:
This process may have multiple commercial advantages including:
- New applications for soybeans which may increase profitability and expand the soybean market.
- Special purpose value added soybeans can be readily created, which may reduce the risk of cardiovascular disease, osteoporosis, various cancers, and have other therapeutic uses.
- Negative phytoestrogens can be lowered, which may lead to improved animal feeds and animal reproduction.
