Comparative phylogeny of rrs and nifH genes in the Bacillaceae [PDF]
The rrs (16S rDNA) gene sequences of nitrogen-fixing endospore-forming bacilli isolated from the rhizosphere of wheat and maize were determined in order to infer their phylogenetic position in the Bacillaceae. These rhizosphere strains form a monophyletic cluster with Paenibacillus azotofixans, Paenibacillus polymyxa and Paenibacillus macerans.

The DNA sequence was determined for the Azospirillum brasilense nifH gene and part of the nifD gene. The nifH gene is 885 bp long and encodes 293 amino acid residues. The region upstream of the nifH open reading frame contains a putative promoter whose sequence shows perfect homology with promoters of other diazotrophic bacteria and two putative ...

Certain multicopy plasmids bearing promoter sequences of nitrogen fixation (nif) genes inhibit expression of chromosomal genes in Nif+ Klebsiella pneumoniae, hence leading to a Nif- phenotype. This 'multicopy inhibition' has been attributed to the titration of the nif-specific activator protein NifA by the plasmid-borne promoter sequences.
