Genetics of oxidative phosphorylation: petite deletion mapping of the Oli 2 region of the mitochondrial genome of Saccharomyces cerevisiae.

Petite deletion mapping has been carried out for the Oli 2 region of the mitochondrial genome of Saccharomyces cerevisiae to produce a fine structure genetic map. Previously unlocated mit- mutants together with the drug resistant loci Oli 2 and Oss 1 have been ordered between the cytochrome oxidase and apocytochrome b genes. As a result of this study a series of isogenic p- clones have been isolated spanning the Oli 2 region.
