Summary Mating competence in the fungusSchizophyllum commune is controlled by two unlinked factors, each of which consists of two closely linked loci. The recombination frequencies between the loci of each factor were determined for a dikaryon and a group of back-crosses, at two meiotic temperatures. The results establish that the frequencies of recombination in the two regions are under genetic control. Although the two regions are similar in structure and function they are under separate recombination control. 相似文献

Summary The hydrolytic enzyme trehalase was demonstrated in mycelial extracts of Schizophyllum commune cultured on either glucose or trehalose as sole source of carbon and energy. The enzyme was also detected in culture-filtrates of trehalose-grown cells. The intracellular forms of trehalase from glucose- and trehalose-cultures were similar in their response to dialysis and heat treatment as well as pH optimum, affinity constant for trehalose and resistance to a variety of sugar alcohols. 相似文献

Summary The detection of chlamydospores of Schizophyllum commune in liquid medium is described. The short thick walled cells are formed by intercalary septation which leads also to modification of the septal complex. The chemical composition of the cell walls of chlamydospores is similar to the composition of the vegetative mycelium. 相似文献

Summary Protoplasts of aSchizophyllum commune tryptophan auxotroph (trp1), deficient in indole-3-glycerol phosphate synthetase (IGPS), were transformed to trp+ with plasmid DNA containing the SchizophyllumTRP1 sequence. Efficiencies up to 30 transformants per microgram of plasmid DNA were obtained. Southern blots reveal that the
transforming DNA is integrated in chromosomal DNA. The trp+ phenotype of transformants is stable in meiosis and mitosis. Transformants possess IGPS activity comparable to wild-type
cells. 相似文献
