Monascus spp. are widely used in the production of monacolin K and food- grade pigments in East Asia. In Aspergillus species, the three transcription factors BrlA → AbaA → WetA sequentially function as the central activators of asexual development (conidiation), leading to the formation of conidiophores. Unlike their close relative Aspergillus spp., Monascus spp. produce basipetospora-type asexual spores (conidia), and their genomes contain homologs of brlA and wetA but not abaA. In the present study, to investigate their roles in Monascus conidiation, MrbrlA and MrwetA were functionally characterized by gene knockout and overexpression in Monascus ruber M7. The results revealed that the deletion and overexpression of MrbrlA and/or MrwetA caused no apparent changes in the morphology, size, number, structure, or germination of conidia. However, deletion and overexpression of MrwetA severely repressed sexual development and affected the production of secondary metabolites. Taken together, these results suggest that the well-established central regulatory model of conidiation in Aspergillus is not applicable in their Monascus relatives. The results of the present study could enrich our understanding of the asexual development regulatory networks in filamentous fungi.
