The mitochondria of filamentous fungi contain a rich array of plasmids and plasmid-like DNAs. In this regard, the fungi appear to be exceptional among eukaryotes, from which a relatively small number of plasmids have been described. In contrast to mitochondrial plasmids, only a few nucleus-associated plasmids are known in lower eukaryotes. Dictyostelium discoideum, for example, contains at least five unrelated nuclear plasmids (21). Several genera of yeast carry nuclear plasmids, of which the 2-micron circle of Saccharomyces cerevisiae is the prototype and the most intensively studied of all eukaryotic plasmids (3). The recently described nuclear kalDNA, from certain strains of Neurospora intermedia, appears to share properties of plasmids and transposons (Ref. 2; Bertrand, this Volume).
