Missouri Researchers Identify Gene That Could Help Protect Soybean Yields

• March 16, 2026

Key Takeaways: 

• Missouri scientists made a breakthrough in soybean pest resistance. Researchers at the University of Missouri identified the GmSNAP14 gene, which plays a key role in how soybean plants respond to soybean cyst nematode—the leading cause of soybean yield loss in the United States.
  
• Farmer-funded research is driving agricultural innovation. The discovery was supported by the Missouri Soybean Merchandising Council, demonstrating how producer-led investment helps accelerate practical solutions for farmers.
  
• Missouri’s research ecosystem supports stronger crops and more resilient agriculture. Discoveries like this give plant breeders new tools to develop improved soybean varieties that can better withstand disease pressure and protect crop productivity.

Missouri continues to play a leading role in advancing agricultural innovation that strengthens farmers’ productivity. Researchers at the University of Missouri have identified a gene that helps soybean plants defend against one of agriculture’s most damaging pests—soybean cyst nematode (SCN), the leading cause of soybean yield loss in the United States.

The discovery of the GmSNAP14 gene, supported by farmer-funded research from the Missouri Soybean Merchandising Council, provides plant breeders with new tools to develop stronger, more resilient soybean varieties. Soybean cyst nematode infects plant roots and quietly reduces yields, often without obvious above-ground symptoms, costing U.S. farmers billions of dollars in lost production each year.

Insights like these help scientists better understand the genetic mechanisms behind pest resistance and give plant breeders new tools to accelerate the development of improved soybean varieties. Over time, these innovations can help farmers better protect yields and maintain productivity in the face of evolving agricultural challenges.

The discovery also highlights Missouri’s broader strengths in agricultural research and plant science. The state is home to a collaborative ecosystem where researchers, farmers, commodity groups, and industry partners work together to develop practical solutions for modern agriculture.

From farmer-led research investment to world-class university science, Missouri continues to play an important role in advancing innovations that help strengthen crop resilience and support the future of food and agriculture.
