The genetic control of DS-RNA virus-like particles associated with Saccharomyces cerevisiae killer yeast

Abstract
Previous results have indicated that laboratory strains of yeast possessing two types of dsRNA virus-like particles, V1 and V2, are capable of producing a killer toxin which kills sensitive strains. This paper reports on genetic crosses which correlate the presence of these particles both with a host nuclear gene /mak1* and with the production of a killer toxin. The results show that:
