Endogenous soybean genes with potential to yield soybean varieties with improved resistance to sudden death syndrome (SDS) in soybeans.

ISU researchers have identified ten soybean genes with markedly reduced gene expression following infection by the fungus Fusarium virguliforme that causes sudden death syndrome in soybeans. The genes are being characterized for resistance to sudden death syndrome in transgenic soybeans and some of the genes look promising. If effective these findings may lead to the development of commercially important sudden death syndrome resistant soybean cultivars.

• Potential for enhanced resistance to soybean pathogens

• Widely accepted approach

• On of the genes shows multiple resistance to Fusarium, Aphids, and Mites
