Isolation and developmentally regulated expression of an Aspergillus nidulans phenol oxidase-encoding gene, ivoB.

Gene - 1 Feb 1991

Birse C E, Clutterbuck A J

Abstract excerpt

Ivory (ivo) mutants of Aspergillus nidulans lack conidiophore pigmentation. We have cloned ivoB which codes for a conidiophore-specific phenol oxidase (AHTase) via the adjacent selectable ureD gene. Gene-library transformants of a ureD4 strain proved defective for the vector, but we recovered both ureD and ivoB from a lambda library of transformant DNA. The ivoB transcription unit was localized to a SalI-XbaI...
