Multiple-allelic incompatibility factors at one locus or at two unlinked loci were reported
almost 50 years ago as the typical systems determining self-sterility and the patterns of …

Materials and Methods. The materials used in this study have been drawn from the world-
wide sample of homokaryotic strains of S. commune that was previously used for a survey of …

Primary mutations in the three classes of the B factor were detected. The mutations map in
the α and β loci of the B factor. The characteristic mating behavior of the mutant strains …

The B factors of Schizophyllum commune were recently shown1 to belong to two groups:"
recombining" factors and" nonrecombining" factors. Factors of the recombining group are …

The B factors of Schizophyllum commune are of 3 classes: The high recombining class I has
7 α alleles and 7 β alleles; the low recombining classes are class II with 7 α allels and …

The genetic nature of the incompatibility factors in the higher fungi has been the subject of
considerable interest for many years. Multiple-allelic incompatibility systems of two types …

MATING competence and sexual morphogenesis in a majority of higher Basidiomycetes,
typified by Schizophyllum commune, are determined and controlled by a bifactorial or" …

Mating competence in a majority of the higher Basidiomycetes, typified by Schizophyllum
commune, is determined by a bifactorial incompatibility system. 1'2 The determination of …

Analysis of genetic crosses among strains of Schizophyllum commune carrying recombining
B factors has revealed that not all heteroallelic pairs of B factors are able to recombine with …

Primary mutations in the alleles α1 and β7 of the B incompatibility factor of Schizophyllum
were induced with X rays. An additional mutation unlinked to the B factor and affecting its …
