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.
We are conducting research to identify biotic and abiotic factors responsible for causing root rot on soybeans, and to estimate potential yield losses caused bysoybeanroot rot. A large component of this study is focused on indentifying the complex of Fusarium species that are pathogenic on soybeans and identify their contribution to reduced soybean productivity. We are also analyzing the relationshipsbetween soil pH, SCN density and root rot severity.
The goal of this project is to identify components of partial resistance to soybean rust by conducting detailed epidemiological studies on the infection process and disease progress over time. One of the objectives of the study is to determine if leaves of different ages vary in their susceptibility to infection by the soybean rust pathogen. This project is in collaboration with the North Florida Research and Education Center of the University of Florida.
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
