Genetic analysis of Aspergillus niger: isolation of chlorate resistance mutants, their use in mitotic mapping and evidence for an eighth linkage group.

Abstract excerpt

This paper describes the use of chlorate resistant mutants in genetic analysis of Aspergillus niger. The isolated mutants could be divided into three phenotypic classes on the basis of nitrogen utilization. These were designated nia, nir and cnx as for Aspergillus nidulans. All mutations were recessive to their wild-type allele in heterokaryons as well as in heterozygous diploids. The mutations belong to nine...
