Evaluate the ability of Syntaxin genes to enhance resistance against Fusarium virguliforme and Heterodera glycines

Abstract

Abstract Soybean sudden death syndrome (SDS) caused by Fusarium virguliforme is a common and widespread disease across soybean-growing regions worldwide. Experiments were conducted in temperature-controlled water baths in the greenhouse to test the effects of some genes from syntaxin group (SYP22-3 and SYP22-4) on F.virguliforme and the combination of SDS and soybean cyst nematode (Heterodera glycines). Both genes were tested in different combinations with currently two pathogens to examine their ability to manage studied pathogens. Syntaxin evaluated on soybean seedlings infected with F. virguliforme alone and both F. virguliforme and H. glycines. Results showed that there were significant effects of syntaxin genes to reduce the foliar disease severity on soybean plants. Furthermore, they reduced the number of H. glycines females cysts compared to control. Data analysis did not show any negative effect by syntaxin genes on plant growth.
