Evidence for the Existence of Mating Subtypes Within the <i>Schizophyllum commune</i>: Mating Behavior and Genetic Divergence.

ABSTRACT: Schizophyllum commune, a Basidiomycota fungus with a tetrapolar mating system, serves as a key model for studying sexual reproduction. In this study, two distinct mating subtypes (I and II) were identified in strain 20R-7-ZF01, isolated from subseafloor sediment, which exhibited eight different mating interaction phenotypes. Intra-subtypes exhibited colony-symmetric tetrapolar interactions (G1), whereas inter-subtype crosses yielded colony-asymmetric phenotypes (G2) and a reduced number of fruiting bodies. Nuclear migration analysis revealed that both subtypes follow the same sexual reproductive process, suggesting functional similarities despite the different reproductive outcomes. Gene silencing of mating-type loci identified the genes bbp2-9 and bbp2-7 within the B
