Evolution of mitochondrial DNA in yeast: gene order and structural organization of the mitochondrial genome of Saccharomyces uvarum.

abstract：:In order to study the mechanism responsible for the uniparental transmission of the mitochondrial genome in crosses between Chlamydomonas reinhardtii and C. smithii, we have analyzed the fate of mitochondrial DNA during gametogenesis, zygospore differentiation and sporulation by hybridization experiments. Both mt+ and...
