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

## Abstract An Rβprime plasmid (pJB3JIβ18) 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. Rβprime plasmids were obtained by transferring R68.45 to ORS571, retransferring it to __E. coli__
The glnA, ntrB and ntrC genes of Klebsiella pneumoniae have been cloned, on a 12 kb HindIII fragment, into the plasmid pACYC184. In a coupled in vitro transcription/translation system the resultant plasmid, pGE100, directed synthesis of five polypeptides (molecular weights 73, 53, 51, 39, 36 kd) fro
