Inheritance 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 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 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 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 کاملInheritance of DNA Methylation in Plant Genome
Genomic DNA contains not only information of DNA sequence, but also epigenetic information that is the direct DNA modification by methylation (the addition of methyl group to the 5th carbon of pyrimidine ring of cytosine) and histone modifications (acetylation, methylation, etc). Epigenetic information is closely related to regulation of gene expression. If a methyl group is dislocated to posit...
