Temperature sensitivity of a nifA-like gene in Enterobacter cloacae.
Nitrogen fixation (nif) genes of Enterobacter cloacae, a rhizosphere diazotroph of rice plants, were identified by using cloned Klebsiella pneumoniae nif gene fragments as probes for molecular hybridization. The product of a nifA-like gene of E. cloacae appeared less temperature sensitive than the K. pneumoniae nifA gene product. This result correlates with the fact that E. cloacae can fix nitrogen at 39 degrees C, while K. pneumoniae cannot.
