title: Nuclear mutants of yeast with reduced spontaneous mutability of the mitochondrial genome.
abstract: Nuclear mutations in yeast were obtained that reduced rates of spontaneous mutations in the mitochondrial genome. The symbol mmg (mutability of mitochondrial genome) is used to designate these mutations. 2 types of mmg mutation are described: semidominant and recessive ones. Each of the 4 mutations studied is located in a separate mmg locus suggesting that there are probably more than 4 mmg loci in the nuclear genome of a yeast cell.
