Molecular Cloning of Nitrogen Fixation Genes from Rhizobium Meliloti
Until recently, the focus of interest in our laboratory has been on cloning nif genes from the free-living nitrogen-fixing species Klebsiella pneumoniae (Cannon et al., 1977; Cannon et al., 1979; Riedel et al., 1979). K. pneumoniae was chosen for the first attempts to clone nif genes because its close resemblance to Escherichia coli allowed it to be directly studied by E. coli genetic techniques.
