摘要： Filamentous fungi reproduce sexually or asexually, and the developmental processes are strictly regulated by a variety of transcription factors. In this study, we characterized a zinc finger transcription factor, called AcrpnR, in Aspergillus cristatus (GME2916). The increment AcrpnR strain exhibited decreased asexual reproduction and increased cleistothecium production. The complementation strain showed restoration of these phenotypic differences. Overexpression of AcrpnR resulted in enhanced asexual development and delayed and inhibited sexual reproduction, suggesting that AcrpnR is required for proper asexual and sexual development in A. cristatus. In addition, AcrpnR positively regulated the expression of genes of the central regulatory pathway of conidiation and negatively regulated the expression of sex-related genes. Overall, these results demonstrate that AcrpnR is essential for maintaining a balance between asexual and sexual development.
