MUTATIONAL ANALYSIS OF NATURAL ALLELES AT THE B INCOMPATIBILITY FACTOR OF SCHIZOPHYLLUM COMMUNE: α2 AND β6

[摘要] The B incompatibility factor of the fungus Schizophyllum commune having allelic specificity α2–β6 was subjected to mutagenesis by X-irradiation. Five types of mutations were recovered, four of them new types previously unreported. All lead to loss of the B -factor regulatory function; three of the five have retained their allelic specificity. The mutations map in three closely linked sites: Bα, Bβ , and between Bα and Bβ .
