Disease relevance of nifD

Although restriction analysis of the nifD- nifK intergenic DNA fragment confirmed the unique nature of Rhizobium sp. strain NGR234, several similarities between Rhizobium sp. strain NGR234 and S. fredii USDA257, the ARDRA analysis and the full sequence of the 16S rDNA confirmed that NGR234 is a S. fredii strain [1].
Clear distinction between Sinorhizobium meliloti and Sinorhizobium medicae were observed by analysis of the IGS symbiotic regions between nifD and nifK genes [2].

High impact information on nifD

Bacterial mutants (fixJ and nifD) and a subset of plant mutants (dnf2, dnf3, dnf4, dnf6, and dnf7) defective for nitrogen fixation induce the above genes [3].
