Title: Small RNAs in S. cerevisiae reconstituted with RNAi      
dateReleased:
08-10-2011
description:
The RNA interference (RNAi) pathway is found in most eukaryotic lineages but curiously is absent in others, including that of Saccharomyces cerevisiae. Here, we show that reconstituting RNAi in S. cerevisiae causes loss of a beneficial dsRNA virus, known as killer virus. Incompatibility between RNAi and killer viruses extends to other fungal species, in that RNAi is absent in all species known to possess dsRNA killer viruses, whereas killer viruses are absent in closely related species that retained RNAi. Thus, the advantage imparted by acquiring and retaining killer viruses explains the persistence of RNAi-deficient species during fungal evolution. Employ high-throughput sequencing of endogenous small RNAs from Saccharomyces cerevisiae wild-type and RNAi-reconstituted strains.
