The fast growing strain, Azorhizobium caulinodans ORS571, isolated from stem nodules of the tropical legume Sesbania rostrata, can grow in the free-living state at the expense of molecular nitrogen. Five point mutants impaired in nitrogen fixation in the free-living state have been complemented by a

The nucleotide sequence of a 4.1 kb DNA fragment containing the fixABC region of Azorhizobium caulinodans was established. The three gene products were very similar to the corresponding polypeptides of Rhizobium meliloti. The C-terminal domains of both fixB products displayed a high degree of simila
## Abstract An R‐prime plasmid (pJB3JI‐18) carrying a 10 kb region of __Azorhizobium caulinodans__ ORS571 DNA which codes for uptake hydrogenase activity was isolated from a Km^8^ derivative of R68.45. R‐prime plasmids were obtained by transferring R68.45 to ORS571, retransferring it to __E. coli__
