I have been focusing on beneficial microbes that are useful in managing diseases, whether in plant health or human health. I am motivated to study microbiomes and viromes because antimicrobial resistance is a substantial cause of death by infectious disease in the United States. The genome of Sclerotinia sclerotiorum has been sequenced and is suitable as a model system from which the most diverse lineages of mycoviruses have been discovered. These mycoviruses include positive- and negative-stranded ssRNA, dsRNA viruses and a ssDNA virus capable of extracellular transmission. Disruption mutants of S. sclerotiorum genes are reasonably easy to obtain. Sclerotinia sclerotiorum has a very broad host range at 400 species. From a genome-wide investigation, we recently summarized a list of fungal mRNA targeted by small RNA-mediated degradation, induced by a virus infection that causes hypovirulence (reduced virulence) of the fungus.
