title: Induction of yeast killer factor mutations.
abstract: Two related killer strains of Saccharomyces cerevisiae were mutagenized and screened for nonkiller variants. About 20% of the mutants derived from one strain lacked all detectable double-straned ribonucleic acid (dsRNA). About 70% of the mutants from the other strain lacked one of the dsRNA species normally associated with the killer factor and had in its place another species of dsRNA with a lower molecular weight.
