title: An intragenic map of the brlA locus of Aspergillus nidulans.
abstract: We have constructed an intragenic map for the Aspergillus nidulans brlA gene, mutants in which are distinguishable by visual criteria only. Most of the leaky phenotype mutants map near the right (3') end. The gene shows distinct recombinational polarity consistent with recombination initiation at the promoter (centromere-proximal) end of the gene. brlA12 and brlA20 mutants gave abnormal DNA restriction patterns consistent with the III; VIII and VI; VIII translocations, respectively, determined by haploidization.
