We study biological functions of secondary metabolites, focusing on plant and fungal defense chemicals, vascular disease caused by Verticillium longisporum, lignans of sesame, and plant root exudates. Our main tools are RNAseq, gene disruption in fungi, DNA-based analysis of microbial communities, chemical analyses, bioassays, and nontargeted metabolic profiling.
