| Abstract: | Mutations resistant to compounds that alter the development of Schizophyllum commune (cyclic adenosine monophosphate, caffeine and imidazole) were selected. These mutations defined four genes, car (cAMP resistance), caf-1 and caf-2 (caffeine resistance) and imr (imidazole resistance). The mutations were found to be noncomplementing in certain pairs when tested against each other and against two previously isolated developmental mutations, B-con and sep (septateless), in fully compatible, forced heterokaryons. The pattern of complementation in fully compatible diploids showed noncomplementation only between allelic mutations, except for one case, imr vs. car. |
