14-3-3 family protein that plays a role in the morphological differentiation and secondary metabolism biosynthesis (PubMed:29247055). Required for normal fungal morphogenesis in an environment-dependent manner, affecting the balance between production of conidiophores and the formation of sclerotia, resistant structures that are necessary for the dissemination and survival (PubMed:29247055). Acts as a positive regulator of conidiation and a negative regulator of sclerotial production (PubMed:29247055). Regulates also the production of secondary metabolites such as aflatoxin, but also the indole-tetramic acid mycotoxin cyclopiazonic acid (CPA) and ustiloxin, an inhibitor of microtubule assembly (PubMed:29247055). Diminishes colony growth and affects conidiation (PubMed:29247055). Decrease in the expression of transcription factors brlA and wetA, components of the central regulatory pathway essential for conidiophore formation (PubMed:29247055). Increases the expression of nsdC, encoding a transcription factor necessary for normal sclerotial production, ans subsequent production of sclerotia (PubMed:29247055). Increases also the production of aflatoxinvia the induction of aflatoxin cluster regulatory genes aflR, aflJ and ver1 (PubMed:29247055). Dicreases the expression of the polyketide synthase-nonribosomal peptide synthetase (PKS/NRPS) gene (AFLA_139490), essential in the synthesis of cyclopiazonic acid (CPA), and of ustD, involved in the production of ustiloxin (PubMed:29247055). Belongs to the 14-3-3 family.
