Physical mapping and genome organization of mitochondrial DNA from Candida maltosa

Summary Mitochondrial (mt) DNA of the ascomycetous yeast Candida maltosa was isolated and characterized. The mtDNA is circular and the size estimated from restriction analysis performed with 7 endonucleases was 52 kb pairs. A restriction map was constructed, using the cleavage data of four endonucleases. Using mt genes from Saccharomyces cerevisiae, six structural genes (large rRNA, apocytochrome b, cytochrome c oxidase subunit I and subunit 11, ATPase subunit 6 and subunit 9) were located on the C. maltosa chondriome by cross hybridization experiments. The comparison between the mt genomes of C. maltosa and six other yeasts showed differences in the overall genome organization.
