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). Responsible for activating a set of genes whose products make up the final two conidial wall layers or direct their assembly and though this activity is responsible for acquisition of spore dormancy (PubMed:8078481). Expression is regulated by the heterotrimeric G protein pga1 (PubMed:18364746). Belongs to the wetA family.
