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 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 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 کاملInheritance of chromosome-length polymorphisms in Coprinus cinereus.
We have investigated the inheritance of chromosome-length polymorphisms in the basidiomycete Coprinus cinereus. The electrophoretic karyotypes of interfertile strains of C. cinereus are strikingly different, and crosses between strains with different karyotypes yield progeny with chromosomes of new sizes. Repeated backcrossing of a mutant to one parent often stabilizes the mutant chromosome at ...
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, ...
