We report here the molecular cloning of the A43 mating type factor from Coprinus cinereus, a basidiomycetous fungus. Our molecular analyses revealed an unexpected source of variation in the A factor. Though genetic studies have demonstrated that A has two subunits, alpha and beta, we located three nonoverlapping fragments in the A43 region that have A factor function following DNA-mediated tran...
Three mutants of horseradish peroxidase isoenzyme C (HRPC) have been constructed in which the conserved distal aromatic residue Phe(41) has been substituted by Trp, Val or Ala and the properties of the mutant proteins have been compared with that of the wild-type. The ferric and ferrous states have been studied by resonance Raman, electronic absorption and Fourier-transform infrared spectroscop...
Abstract The aim of this study was to evaluate the effect allyl isothiocyanate (AITC) on reactive oxygen species (ROS) metabolism and quality postharvest Coprinus comatus (C. comatus). Fresh mushrooms were stored at 4 °C with AITC 5, 10, 20 μL/L for 18 d, respectively. Sampling performed every 3 physicochemical parameters ROS related enzymes activities analyzed. Compared control, application 10...
A homokaryotic strain (5337) in our culture stock of Coprinus cinereus produced fertile fruit bodies after prolonged culture. Microscopic examination revealed that hyphae dedifferentiated from the tissues of one of the fruit bodies, as well as all basidiospore derivatives from the fruit body, exhibited pseudoclamps, whereas vegetative hyphae of 5337, from which the fruit body developed, had no ...
The A mating type locus of Coprinus cinereus is remarkable for its extreme diversity, with over 100 different alleles in natural populations. Classical genetic studies have demonstrated that this hypervariability arises in part from recombination between two subloci of A, alpha and beta, although more recent population genetic data have indicated a third segregating sublocus. In this study, we ...
Pheromone signaling plays an essential role in the mating and sexual development of mushroom fungi. Multiallelic genes encoding the peptide pheromones and their cognate 7-transmembrane helix (7-TM) receptors are sequestered in the B mating type locus. Here we describe the isolation of the B6 mating type locus of Coprinus cinereus. DNA sequencing and transformation analysis identified nine genes...
