Abstract
Reproductive differentiation in the basidiomycete Schizophyllum commune Fr. is initiated by plasmogamy and reciprocal nuclear migration and is terminated by the production of basidiospores. The work reported here has analyzed several factors that affect 2 sequential steps in reproductive differentiation: A) the formation of aggregated masses of cells, and B) the subsequent differentiation of fruiting bodies. The 2 steps are both photosensitive: A) light accelerates the formation of aggregated masses of cells; B) a short exposure of light induces nonaggregated dikaryotic cells to form mature fruiting bodies in the dark.
