Some of the species within Basidiomycota have the most complex systems of sexual reproduction known among fungi. In general for fungi there are two main types of sexual reproduction: homothallism, when mating occurs within a single individual, or in other words each individual is self-fertile; and heterothallism, when hyphae from a single individual are self-sterile and need to interact with another compatible individual for mating to take place. Additionally, mating compat… WebAspergillus fungi, gained from comparative genomics analyses. S. cerevisiae Ste12p is a target of Fus3p MAPK in the mating–pheromone response pathway, and of Kss1p MAPK in the pseudohyphal development pathway.82) The Ste12-like protein SteA in A. nidulans lacks the Kss1p-interacting domain present in Ste12p, and instead has C-terminal C 2/H 2 Zn
