The Aspergillus nidulans rcoA gene is required for veA-dependent sexual development

Abstract

The Aspergillus nidulans rcoAΔ mutant exhibits growth and developmental defects. We show that the rcoAD mutant lacks cleistothecia and is self-sterile. In crosses with wild-type strains, rcoAΔ 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 sexual development pathway.
