BrlA, abaA and wetA are pivotal regulators of conidiophore development and conidium maturation (PubMed:8508769, PubMed:5366214, PubMed:2823119, PubMed:2655931, PubMed:2196567,PubMed:7704830). They act individually and together to regulate their own expression and that of numerous other sporulation-specific genes (PubMed:2823119, PubMed:2655931, PubMed:2108321). Binds promoters of target genes at brlA response elements (BREs) containing the conserved sequence 5'-(C/A)(A/G)AGGG(G/A)-3' (PubMed:8417986). Controls the expression of the conidiophore-specific phenol oxidase ivoB (PubMed:1901560). Controls the expression of the hydrophobin rodA (PubMed:2065971). Mediates the developmental switch from the indeterminate, apical growth pattern of vegetative cells to the budding growth pattern of conidiophores (PubMed:3293800). Expression of brlA leads to activation of abaA, wetA and stuA, cessation of vegetative growth, cellular vacuolization and spore formation. Expression is induced during conidiation, after conidiophore stalks had formed and had begun to vesiculate (PubMed:2823119). Positively regulated by abaA (PubMed:2655931). Negatively regulated by velC (PubMed:24587098). Expression is also controlled by acoD (PubMed:1508186). Both zinc fingers are required to induce development (PubMed:2108321). Prevents the formation of normal conidiophores (PubMed:2823119).
