Department of Biological Sciences' Paul Rowley, Angela Crabtree, Emily Kizer and James Van Leuven, as well as Samuel Hunter, Daniel New and Matthew Fagnan with the Institute for Bioinformatics and Evolutionary Studies (IBEST) Genomics Resources Core published a study in the journal Viruses. Brewer's and Baker's yeast play host to many viruses that have genomes made of double-stranded RNA. This type of genetic material is labor-intensive and time-consuming to analyze. The team created a new method to purify and sequence the double-stranded RNAs of two mycoviruses in yeast. They discovered new mutations in the RNA that increased the toxicity of an antifungal drug produced by yeast.
