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). Acts as a crucial regulator of both conidiation capacity and conidial quality (PubMed:26243054). Plays a role in virulence (PubMed:26243054). Leads to slower germination, lower hydrophobivity and lower virulence of conidia (PubMed:26243054). Belongs to the wetA family.
