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). Functions to maintain conidial dormancy by suppressing microcycle conidiation (PubMed:24186953). Expression is positively regulated by flbD (PubMed:25277408). Results in abnormal production of conidiophores and conidia, including longer conidia with fewer septa, conidia sensitivity to acute stresses such as oxidative stress and heat stress, and vigorous generation of single-celled conidia through autophagy-dependent microcycle conidiation (PubMed:24186953). Reduces the survival rate of aged conidia (PubMed:24186953). Belongs to the wetA family. Truncated N-terminus.
