Infection by dsRNA viruses is associated with enhanced sporulation efficiency in Saccharoymces cerevisiae

Thomas Travers Cook, Christina Skirgaila, Oliver Martin & Claudia Buser
Upon starvation, diploid cells of the facultative sexual yeast Saccharoymces cerevisiae undergo sporulation, forming four metabolically quiescent and robust haploid spores encased in a degradable ascus. All endosymbionts, whether they provide net benefits or costs, utilise host resources; in yeast, this should induce an earlier onset of sporulation. Here, we tested whether the presence of endosymbiotic dsRNA viruses (M satellite and L-A helper) correspond with higher sporulation rate of their host, S. cerevisiae. We find...
