Abstract

Genetic and reversion analyses of a thermosensitive pleiotropic mutant strain of with defects in nitrogen fixation and nitrogen metabolism have shown that the pleiotropic behaviour of the mutant is due to a single mutation in a gene designated . This gene is cotransducible with at a frequency of about 30% (using bacteriophage P1) and with at a frequency of about 14%. The gene order is . The defect in the mutant is complemented by the F′ element, F′148.
