Restriction enzyme fragment patterns of mtDNA from a galactose oxidase-producing mold.
1. Mitochondrial DNAs from Dactylium dendroides, Hypomyces rosellus, Fusarium graminearum, Gibberella fujikuroi, Fusarium tricinctum strains and a galactose oxidase (GAO)-producing mold (original strain) presented distinctive restriction enzyme fragment patterns with the endonucleases Hind III and EcoRI. 2. A small number of comigrating bands was found when the GAO-producing mold was compared with the others. The molecular size of mtDNA from the GAO-producing mold, as judged by summation of fragment sizes produced by digestion with EcoRI, Hind III and Bgl II, is 61.3 +/- 2.16 kb. 3. The results suggest that the mtDNA from the GAO-producing mold strain is distinct from that of D. dendroides and all other ascomycetes analyzed.
