A comparison of three fission yeast mitochondrial genomes.

ABSTRACT: The fission yeasts are members of the fungal order Schizosaccharomycetales, a candidate deep-diverging group within Ascomycota. Although a great deal of molecular information is available from Schizosaccharomyces pombe, a model eukaryote, very little is available from other members of this group. In order to better characterize mitochondrial genome evolution in this fungal lineage, the mitochondrial DNA (mtDNA) of two additional fission yeasts, Schizosaccharomyces octosporus and Schizosaccharomyces japonicus var. japonicus, was sequenced. Whereas the mtDNA of S.pombe is only 19 431 bp, the mtDNA of S.octosporus is 44 227 bp, and that of S.japonicus var. japonicus is over 80 kb. The size variation of these mtDNAs is due largely to non-coding regions. The gene content in the latter two mtDNA
