Scientists to Identify Genes that can Combat RKN Parasite in Soybean

Scientists from the University of Missouri and the University of Georgia in the United States; and the Beijing Genome Institute in China attempted to identify two genes that can defend soybeans from damage caused by the root-knot nematode (RKN) parasite. RKN parasite causes millions of dollars in yield losses each year in the United States.

This is the first time the process has been used in soybean research. Using another genetic technique, the team is now working to identify the specific gene that prevents RKN from infecting the soybean. With this knowledge, resistant soybean varieties or cultivars can be bred for farmers.
