Abstract
The cytoplasmically inherited M double-stranded (ds) RNA genome segmen t of killer virus of Saccharomyces cerevisiae is heat-curable in some yeast strains but not in others. Temperature sensitivity is conferred on both M1 and M2 dsRNA satellite virus segments by the L-A-HN allele of the killer helper virus genome, but not by the L-A-H allele. Both d iploidy and mating type heterozygosity of the host cell are also corre lated with increased virus curability.
