Genetic Recombination in a Common-B Cross of Schizophyllum commune


THIS communication reports the synthesis of stable common-B heterokaryons in Schizophyllum commune, and the occurrence of normal genetic recombination in fruit-bodies derived therefrom. Although common B heterokaryosis and the normal segregation of the A-factor in common-B fruit-bodies have been reported in other tetrapolar species1–3, these phenomena in S. commune have not been demonstrated with certainty4,5. The nature of production of spores in such fruit-bodies, however, has not been fully determined, and “It appears uncertain, whether such fruit-bodies are apomictic or functionally bipolar”6.
