New approach uses wild genes to improve biological nitrogen fixation in soybeans

It’s a clever genetic approach to identify genes present in the wild soybean ancestor that might improve or enhance interactions between the modern cultivated soybean and its symbiotic partner S. fredii. Soybean was domesticated so long ago that most cultivated lines lack these ancient traits. This approach will help them to access some of the genetic diversity of the soybean ancestor to improve biological nitrogen fixation of modern soybean cultivars.
