Abstract excerpt
Using Saccharomyces cerevisiae as a model organism, we analyzed the consequences of disrupting mitochondrial function on mutagenesis of the nuclear genome. We measured the frequency of canavanine-resistant colonies as a measure of nuclear mutator phenotype. Our data suggest that mitochondrial dysfunction leads to a nuclear mutator phenotype (i) when oxidative phosphorylation is blocked in wild-type yeast at...
