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:29958281). 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:29958281). Expression increases significantly during initiation of conidiation and remains elevated until colourisation is stabilized (PubMed:29958281). Expression is positively regulated by BrlA (PubMed:29958281). Produces phialides on which short deformed hypha are formed. Belongs to the TEC1 family.
