A distinctive phenotype in the common-A heterokaryon of Coprinus cinereus

抄録

The homobasidiomycete Coprinus cinereus, unlike Schizophyllum commune, is not known to exhibit an obvious heterokaryotic phenotype in common-A matings. In the present study we found that progeny isolated from a fruit-body collected in the field exhibit a distinctive mycelial development in common-A matings. Genetic analysis suggested that the common-A heterokaryotic phenotype is brought about by a nuclear factor(s) other than the mating type genes.
