Mitochondrial DNA was isolated from a yeast-like microorganism, Endomy
ces (Dipodascus) magnusii. The mtDNA consisted of circular molecules 4
0.4 kb long. A restriction map was constructed using the cleavage data
of seven endonucleases. The arrangement of several genes within the m
itochondrial genome of E. magnusii was established by specific hybridi
zation with probes prepared from the mtDNA of Saccharomyces cerevisiae
.
