Several of our projects focus on understanding how the sudden death syndrome (SDS) pathogen, Fusarium virguliforme, causes disease on soybeans. We have been investigating the root infection process, and determining how soil temperature and plant growth stage at time of infection affects the development of the disease. We are also comparing the susceptibility of soybean plants of different genetic backgrounds to pathogen toxins.
This project focuses on clarifying the mechanisms behind the interaction between the soybean cyst nematode (SCN) and the SDS pathogen. We are comparing the infection process of Fusarium virguliforme alone and in the presence of SCN to understand if the interaction between the two pathogens is mechanical and localized, or systemic in nature. This is part of a multistate project with the goal ofidentifying rhizosphere organisms and soil abiotic factors that interact with F. virguliforme in causing SDS.

We are working on several projects focused on identifying sources of soybean resistance to SDS. In one project we are searching for soybean genes involved in resistance to the SDS pathogen using a virus-induced gene silencing approach. Read more about Soybean resistance to sudden death syndrome
