Molecular analysis of pcc1, a gene that leads to A-regulated sexual morphogenesis in Coprinus cinereus.
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 ...
متن کاملLife 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 کاملThe origin of multiple B mating specificities in Coprinus cinereus.
Mushrooms, such as Coprinus cinereus, possess large families of pheromones and G-protein-coupled receptors that are sequestered at the B mating-type locus and whose function is to confer vast numbers of different mating types. This ability results from complex patterns of cognate and noncognate pheromone/receptor pairings, which potentially offer a unique insight into the molecular interaction ...
متن کاملKinetics and mechanics of stem gravitropism in Coprinus cinereus.
Using video recordings we have completed the first kinetic analysis of mushroom stem gravitropism. The stem became gravireceptive after completion of meiosis, beginning to bend within 30 minutes of being placed horizontal. Stem bending first occurred in the apical 15% of its length, then the position of the bend moved rapidly towards the base, traversing 40% of stem length in 2.5 h. Meanwhile, ...
متن کاملCo-ordinate Regulation of Enzymes Involved in Ornithine Metabolism and its Relation to Sporophore Morphogenesis in Coprinus cinereus
Arginine synthesis and urea formation via the ornithine cycle occurred in sporophore cap and stipe of Coprinus cinereus. Although urease was found at high activity in mycelium and stipe, it was not detectable in extracts of cap tissue, but arginine biosynthesis was specifically amplified during development of the cap as judged from metabolism of isotopically labelled substrates and increased en...
