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