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...
متن کاملPatterns 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...
متن کاملAn 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...
متن کاملDe novo methylation of repeated sequences in Coprinus cinereus.
We have examined the stability of duplicated DNA sequences in the sexual phase of the life cycle of the basidiomycete fungus, Coprinus cinereus. We observed premeiotic de novo methylation in haploid nuclei containing either a triplication, a tandem duplication, or an ectopic duplication. Methylation changes were not observed in unique sequences. Repeated sequences underwent methylation changes ...
متن کاملMolecular characterization of laccase genes from the basidiomycete Coprinus cinereus and heterologous expression of the laccase lcc1.
A laccase from Coprinus cinereus is active at alkaline pH, an essential property for some potential applications. We cloned and sequenced three laccase genes (lcc1, lcc2, and lcc3) from the ink cap basidiomycete C. cinereus. The lcc1 gene contained 7 introns, while both lcc2 and lcc3 contained 13 introns. The predicted mature proteins (Lcc1 to Lcc3) are 58 to 80% identical at the amino acid lev...
