Expression of asexual developmental regulator gene abaA is affected in the double mutants of classes I and II chitin synthase genes, chsC and chsA, of Aspergillus nidulans.

Abstract excerpt

The chsA and chsC encode classes II and I chitin synthases, respectively, of the filamentous fungus Aspergillus nidulans. The DeltachsA DeltachsC double mutants (DeltaAC mutants) show defects in asexual development: a striking reduction in the number of conidiophores and aberrant conidiophore morphology. Here, we examined the involvement of regulatory genes for asexual development (brlA, abaA, and medA) in the...
