Secondary Metabolism and Development Is Mediated by LlmF Control of VeA Subcellular Localization in Aspergillus nidulans
Secondary metabolism and development are linked in Aspergillus through the conserved regulatory velvet complex composed of VeA, VelB, and LaeA. The founding member of the velvet complex, VeA, shuttles between the cytoplasm and nucleus in response to alterations in light. Here we describe a new interaction partner of VeA identified through a reverse genetics screen looking for LaeA-like methyltr...
متن کاملThe Aspergillus nidulans rcoA gene is required for veA-dependent sexual development.
The Aspergillus nidulans rcoADelta mutant exhibits growth and developmental defects. We show that the rcoADelta mutant lacks cleistothecia and is self-sterile. In crosses with wild-type strains, rcoADelta nuclei do not contribute to the cleistothecial walls. Furthermore, sexual development resulting from veA overexpression is rcoA dependent, indicating that rcoA lies downstream of veA in the se...
متن کاملThe expression of sterigmatocystin and penicillin genes in Aspergillus nidulans is controlled by veA, a gene required for sexual development.
Secondary metabolism is commonly associated with morphological development in microorganisms, including fungi. We found that veA, a gene previously shown to control the Aspergillus nidulans sexual/asexual developmental ratio in response to light, also controls secondary metabolism. Specifically, veA regulates the expression of genes implicated in the synthesis of the mycotoxin sterigmatocystin ...
متن کاملFunctional characterization and localization of the Aspergillus nidulans formin SEPA.
Formins are a family of multidomain scaffold proteins involved in actin-dependent morphogenetic events. In Aspergillus nidulans, the formin SEPA participates in two actin-mediated processes, septum formation and polarized growth. In this study, we use a new null mutant to demonstrate that SEPA is required for the formation of actin rings at septation sites. In addition, we find that a functiona...
