BrlA, abaA and wetA are pivotal regulators of conidiophore development and conidium maturation. They act individually and together to regulate their own expression and that of numerous other sporulation-specific genes (PubMed:28447400). BrlA, abaA and wetA act together to positively regulate the expression of the Pks1 gene cluster that mediates the biosynthesis of an anthraquinone derivative pigment that contributes to conidial pigmentation that provides protection from UV radiation, heat and cold stress (PubMed:28447400). Expression remains constant during conidiation (PubMed:28447400). Expression is positively regulated by BrlA and AbaA (PubMed:28447400). Produces fewer branches per conidiophore and thus has significantly lower conidial yields. Belongs to the wetA family.
