title: New leucine auxotrophs of Aspergillus nidulans.
abstract: A series of Aspergillus nidulans leucine auxotrophs were isolated after nitroquinoline-1-oxide treatment and analyzed. Four complementation groups could be distinguished in addition to the previously known leuA group. A putative mutant for isopropylmalate isomerase (leuB) was mapped on chromosome I and found to be closely linked to leuA.
