Identification and characterization of a stachyose synthase gene controlling reduced stachyose content in soybean.

ABSTRACT:

Key message

We identified and characterized a mutant of soybean stachyose synthase gene controlling reduced stachyose content which benefit the soybean seed composition breeding program in the future. It has been shown that in soybean, increased sucrose and reduced raffinose family oligosaccharides would have a positive impact on the world's feed industry by improving digestibility and feed efficiency. We searched for new sources of modified oligosaccharide content in a subset of the USDA Soybean Germplasm Collection and then identified plant introduction (PI) 603176A as having ultra-low stachyose content (0.5%). We identified a 33-bp deletion mutant in the putative stachyose synthase gene (STS gene, Glyma19g40550) of PI 603176A. A co-dominate indel marker was successfully develope
