Summary Mitochondrial DNA (mtDNA) found in the basidiomycete Schizophyllum commune (strain 4–40) is a circular molecule 49.75 kbp in lenght. A physical map containing 61 restriction sites revealed no repeat structures. Cloned genes from Neurospora crassa, Aspergillus nidulans, and Saccharomyces cerevisiae were used in Southern hybridizations to locate nine mitochondrial genes, including a possible pseudogene of ATPase 9, on the restriction map. A probe from a functional ATPase 9 gene identified homologous fragments only in the nuclear genome of S. commune. Restriction fragment length polymorphisms (RFLPs) between mtDNA isolated from different strains of S. commune were used to show that mitochondria do not migrate with nuclei during dikaryosis.
