The areA(r) mutation of Aspergillus nidulans confers low pH sensitivity in the presence of ammonium as the only nitrogen source.

Letters in applied microbiology - 1 Jul 1998

Pereira M, Martinez-Rossi N M

Abstract excerpt

The utilization of nitrogen sources by the fungus Aspergillus nidulans is controlled by a mechanism mediated by areA, a wide domain regulatory gene. It has been verified that the strains carrying the mutant allele areAr are inhibited when growing at low pH in the presence of ammonium as the only nitrogen source. The genetic analysis of this marker showed that it apparently maps at the areA locus.
