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:2655931). Responsible for activating a set of genes whose products make up the final two conidial wall layers or direct their assembly and, through this activity, is responsible for acquisition of spore dormancy (PubMed:1986246, PubMed:2180753, PubMed:7704830). The wetA gene is activated only during conidiophore development, and its mRNA accumulates preferentially in mature conidia. Expression is induced during conidiation, after conidia had begun to form (PubMed:2823119). Positively regulated by abaA (PubMed:2655931). Negatively regulated by velC (PubMed:24587098). Has an acidic N-terminus (AA 1-52) followed by a Ser-, Thr-, Pro-rich domain (AA 125-233) and a basic C-terminus (AA 461-555). Prevents the formation of normal conidiophores (PubMed:2823119). Belongs to the wetA family.
