A comprehensive evaluation of PCR primers to amplify the nifH gene of nitrogenase. [PDF]
PLoS ONE, 2012 The nifH gene is the most widely sequenced marker gene used to identify nitrogen-fixing Bacteria and Archaea. Numerous PCR primers have been designed to amplify nifH, but a comprehensive evaluation of nifH PCR primers has not been performed. We performed

nifH gene expression and diversity in geothermal springs of Tengchong, China. [PDF]
Front Microbiol, 2022 Terrestrial hot springs have been suggested to harbor diverse diazotrophic lineages by using DNA-based nifH gene phylogenetic analysis. However, only a small amount of diazotrophs were ever confirmed to perform nitrogen fixation.

nifH genes in the obligate methane oxidizing bacteria [PDF]
FEMS Microbiology Letters, 1988 The hifH gene from Klebsiella pneumoniae, which codes for the Fe protein component of nitrogenase, was used as a probe to detect nifH homologues in total cellular DNA from 13 obligate methane oxidizing bacteria. All but one of those strains that had previously been shown capable of fixing dinitrogen contained sequences homologous to nifH.

Detection and characterization of cyanobacterial nifH genes [PDF]
Applied and Environmental Microbiology, 1994 The DNA sequence of a 359-bp fragment of nifH was determined for the heterocystous strains Anabaena sp. strain CA (ATCC 33047), Nostoc muscorum UTEX 1933, a Nostoc sp., Gloeothece sp. strain ATCC 27152, Lyngbya lagerheimii UTEX 1930, and Plectonema boryanum IU 594.

Comparative phylogeny of rrs and nifH genes in the Bacillaceae [PDF]
International Journal of Systematic and Evolutionary Microbiology, 1999 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.

Isolation of Glucose Fermenting Nitrogen Fixing Gene (nifH) Containing Endophytic Bacteria from Seed and Roots of Wheat (Triticum aestivation l.) [PDF]
, 2023 The present study was conducted to study the nifH gene containing endophytic bacterial frequency in wheat seed and roots obtained from the soil of Chitwan and Kaski. One hundred and four isolates were studied for the presence of the nifH gene.

Cloning and sequencing of the nifH gene ofDesulfovibrio gigas [PDF]
FEMS Microbiology Letters, 1989 The Desulfovibrio gigas nifH gene has been cloned and sequenced. It consists of an open-reading frame of 822 base pairs encoding a 274 amino acid polypeptide. A potential ntrA-dependent promotor sequence is present. The gene lacks an upstream activator sequence homologous to those often found in nif genes subject to activation by nifA.
