Abstract

Long-term storage at +4°C and cultivation at +30°C changes the spontaneous mutation rate of the yeast Saccharomyces cerevisiae double mutants rad52hsm3Δ and rad52hsm6-1. Combinations of hsm3 and hsm6 mutations with rad52 mutation lead to a decrease of the spontaneous mutation rate mediated by DNA repair synthesis in multiply replanted strains in comparison with the same strains investigated right after RAD52 gene decay. Combinations of hsm3 and hsm6 mutations with mutations in other genes of the RAD52 epistatic group did not provide a spontaneous mutation rate decrease.
