A Second Double-Stranded RNA Virus from Yeast

Two double-stranded RNA viruses exist as permanent persistent infections of the yeastSaccharomyces cerevisiae:ScVL1 and ScVLa. Both belong to the Totiviridae, which include a number of fungal and protozoan double-stranded RNA viruses. Although ScVL1 and ScVLa share the same genomic organization and...

description Two double-stranded RNA viruses exist as permanent persistent infections of the yeastSaccharomyces cerevisiae:ScVL1 and ScVLa. Both belong to the Totiviridae, which include a number of fungal and protozoan double-stranded RNA viruses. Although ScVL1 and ScVLa share the same genomic organization and mode of expression and coexist in the same cells, they show no evidence of recombination: with one limited exception, sequence conservation is detectable only in regions conserved in all totiviruses. Both have two open reading frames on their single essential RNAs:cap(encoding a capsid polypeptide) andpol(encoding an RNA-dependent RNA polymerase). The ScVLa virus, like ScVL1, appears to express its Pol domain by a −1 translational frameshift.
