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.
