DNA polymerase of a basidiomycete fungus, Coprinus cinereus

Life history and developmental processes in the basidiomycete Coprinus cinereus.

Coprinus cinereus has two main types of mycelia, the asexual monokaryon and the sexual dikaryon, formed by fusion of compatible monokaryons. Syngamy (plasmogamy) and karyogamy are spatially and temporally separated, which is typical for basidiomycetous fungi. This property of the dikaryon enables an easy exchange of nuclear partners in further dikaryotic-monokaryotic and dikaryotic-dikaryotic m...

Patterns of mating and mitochondrial DNA inheritance in the agaric Basidiomycete Coprinus cinereus.

Patterns of mating and mitochondrial DNA (mtDNA) inheritance were investigated for the Basidiomycete, Coprinus cinereus in order to better understand the relationship of reproductive biology and mtDNA evolution in fungi. Results showed that the unique mating system of basidiomycetes can lead to the formation of mitochondrial mosaics (i.e., colonies composed of sectors differing in mtDNA). Mitoc...

An endo-exonuclease from meiotic tissues of the basidiomycete Coprinus cinereus. Its purification and characterization.

An endo-exonuclease has been identified and partially purified from the basidiocarp tissues of the basidiomycete Coprinus cinereus, which include synchronous meiosis at karyogamy-pachytene stages. Its peak activity appears during the meiotic prophase. The Coprinus endo-exonuclease has a single-strand specific endonuclease activity that converts the supercoiled DNA to relaxed DNA. The endonucleo...

A novel form of ubiquitin found in the basidiomycete fungus, Coprinus congregatus.

Ubiquitin is considered one of the most highly conserved eukaryotic proteins. A remarkable 72 out of 76 amino acid residues are invariant in the ubiquitins of fungi, plants and vertebrates. To date, the ubiquitin sequences of only two fungi have been reported, those of Sacchoromyces cerevisiae (1) and Neurospora crassa (2). These fungi are both ascomycetes, and not surprisingly their ubiquitin ...
