Transfer and expression of Klebsiella nif genes in Alcaligenes faecalis, a nitrogen-fixing bacterium associated with rice root

Since the original construction of diazotrophic Escherichia coli by conjugal transfer of nif genes from Klebsiella pneumoniae in 1972, the manipulation of nif genes into alien prokaryotic backgrounds has become routine: much of the basic genetics of the K. pneumoniae nif cluster was elucidated in an E. coli background. Gene transfers to new species and genera can give new information regarding the stability of nif genes and, particularly, conditions for their expression; recipients in which nif is partly expressed, or not expressed at all, are especially useful. Appropriate examples are discussed. New diazotrophic prokaryotes show little promise for practical exploitation but their construction should give forewarning of problems to be expected in the construction of diazotrophic eukaryotes, as well as hints concerning the ecology and evolution of diazotrophy.
