BrlA, abaA and wetA are pivotal regulators of conidiophore development and conidium maturation (By similarity). They act individually and together to regulate their own expression and that of numerous other sporulation-specific genes (By similarity). Plays a crucial role in pigmentation and conidial cell wall integrity (PubMed:25530311). Totally blocks pigmentation of conidia and leads to colonies with on a white tinge (PubMed:25530311). Belongs to the wetA family.
