Cloned homobasidiomycete TRP2 genes for Agaricus bisporus and Coprinus bilanatus were sequence-characterised. Both genes encode tri-functional proteins with activity domains for glutamine amidotransferase (GAT; G domain), indole glycerol phosphate synthase (InGP; C domain) and phosphoribosyl anthranilate isomerase (F domain). A conserved intron disrupts the GAT-coding sequence in both genes. Co...

In the mushroom Coprinus cinereus, the multiallelic B mating type genes are predicted to encode a large family of seven-transmembrane domain receptors and CaaX-modified pheromones. We have shown that a single amino acid change Q229P in transmembrane domain VI of one receptor confers a self-compatible mating phenotype. Using a heterologous yeast assay, we have demonstrated that this C.cinereus p...

We searched the genome database of the basidiomycete Coprinopsis cinerea (Coprinus cinereus) and found five genes encoding the glycoside hydrolase family 6 (GH6) enzyme, CcCel6A, CcCel6B, CcCel6C, CcCel6D, and CcCel6E, designated in order of increasing locus number (CC1G_01107.1, CC1G_04166.1, CC1G_08276.1, CC1G_08277.1, and CC1G_10605.1). The amino acid sequence of CcCel6A suggests a two-domai...

The glucose analogue 2-deoxy-D-glucose seriously inhibits the growth of Coprinus lagopus. Following treatment with iV-methyl-iV'-nitro-i^nitrosoguanidine 388 resistant mutants were isolated. It is shown that the mutants isolated are probably allelic; they were phenotypically similar and no complementation was observed. The mutants were pleiotropic in the sense that although they were initially ...
