| Abstract: | Thirteen cadmium-resistant mutants ofAspergillus nidulans have been isolated which can grow on higher levels of cadmium than can wild-type strains. In each case, resistance results from a single gene mutation: these identify two new loci. Three mutants are located in thecadA gene on chromosome IV; the other ten have been mapped to thecadB locus, which is tightly linked to themethB gene on chromosome VI. |
