ABSTRACT
We have determined the size, the restriction map and the gene order of the mitochondrial genome of the yeast Saccharomyces uvarum. Sequence analysis of the mitochondrial COXII gene confirmed the position of this yeast in the Saccharomyces cerevisiae-like group, near Saccharomyces cerevisiae and Saccharomyces douglasii. Most mitochondrial genes have been positioned on this approximately 57-kb long genome and three regions containing putative replication origins have been identified. The gene order of S. uvarum suggests that the mitochondrial genome of the S.cerevisiae-like yeasts could have evolved from an ancestral molecule, similar to that of S. uvarum, through specific genome rearrangements.
