Site‐specific mutations were contructed within Bradyrhizobium japonicum fixA, B and C regions that had previously been identified by interspecies hybridization [(1985) Mol.Gen.Genet. 199, 315‐322]. The corresponding mutants were not only Fix− in otherwise fully developed soybean root nodules but also Nif− in free‐living microaerobic culture. Specific fixA, B and C probes hybridized to DNA of the aerobic diazotroph, Azotobacter vinelandii. We hypothesize, therefore, that fixA, B and C genes are of general importance for aerobic/microaerobic nitrogen fixation.
