Mitochondrial genome evolution in a single protoploid yeast species.

ABSTRACT: Mitochondria are organelles, which play a key role in some essential functions, including respiration, metabolite biosynthesis, ion homeostasis, and apoptosis. The vast numbers of mitochondrial DNA (mtDNA) sequences of various yeast species, which have recently been published, have also helped to elucidate the structural diversity of these genomes. Although a large corpus of data are now available on the diversity of yeast species, little is known so far about the mtDNA diversity in single yeast species. To study the genetic variations occurring in the mtDNA of wild yeast isolates, we performed a genome-wide polymorphism survey on the mtDNA of 18 Lachancea kluyveri (formerly Saccharomyces kluyveri) strains. We determined the complete mt genome sequences of strains isolated from various geo
