Nitrogen fixation (nif) genes of Rhizobium leguminosarum were transferred to nif Klebsiella pneumoniae and E. coli by conjugation after partial heat induction of RP4 :: Mu cts in Rhizobium R+ transconjugant, and the hybrid plasmids in the transconjugant strains were isolated and characterized. In order to transfer the nif genes from Rhizobium, the hybrid plasmid RP4 :: Mu cts was transferred by conjugation from E. coli to the symbiotic nitrogen fixer, R. leguminosarum. After stability test, the RP4 :: Mu cts in Rhizobium R+ transconjugant was subjected to partial heat induction by culturing it statically at 38 deg C for 16 hrs, and then conjugated with the nif defective mutant strains of K. pneumoniae or nif mutant strains of E. coli having whole nif gene plasmid
