Regulatory pathway of asexual sporulation in A. nidulans. a Central regulators, upstream activators, negative regulators, velvet regulators, and light-responsive regulators are illustrated by green, light purple, blue, dark purple, and red icons, respectively. b Distribution of central regulators for asexual sporulation in 85 fungi. These fungi are representatives from the phyla Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota. Their genome protein sequences were searched for homologs of AbaA, BrlA, and WetA by BlastP using sequences of A. nidulans AbaA, BrlA, and WetA as queries. Details of these fungi are presented in Central Regulator Strain Information. As shown, BrlA seems to be limited to the Eurotiales group, suggesting a specific role for conidiation in Eurotiales fungi. By contrast, WetA is widely distributed in Pezizomycotina fungi, which suggests a general function for the synthesis of cell wall layers to make conidia mature and impermeable. Surprisingly, AbaA is widespread being found in the phyla Ascomycota, Basidiomycota, and Zygomycota, suggesting that AbaA is involved not only in conidial development, but also has other general functions in fungal development
