The function of the mating-type locus in filamentous Ascomycetes

Heterothallism in the Euascomycetes has been of interest to mycologists ever since its discovery by Dodge (1920) in Ascobolus magnificus. In this classic paper, he showed that heterothallism in this species is a genetically determined condition in which the two mating groups (A, a) are determined by the two alleles (A, a) at a single locus. About a decade later, Gwynne-Vaughan and Williamson (1932) proved that the two mating groups are not the opposite sexes; that is, all strains are hermaphroditic.
