1. Phylogenetics of Xylaria sp. associated to an emerging disease of soybean, namely “Taproot Decline (TRD)”, across southern United States. We hypothesize that this pathogen might represent a novel species in the genus Xylaria. Detailed morphological features and species description if warranted.
2. Population genetics study, targeting the genome of the fungus at a higher resolution, which might help elucidate where the pathogen originated, its patterns of dispersal, and evolutionary relationships among populations of taproot decline pathogen in the region.
3. Development of an in vitro protocol for rapid testing of soybean cultivars for resistance against TRD. Phytotoxic mycotoxins produced by the fungus are currently being tested and characterized.
