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.

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.

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.

The response of diazotrophs to nutrient amendment in the South China Sea and western North Pacific [PDF]
Biogeosciences, 2022 The availability of iron (Fe) and phosphorus (P) has been shown to be a key factor regulating rates of nitrogen fixation in the western subtropical Pacific.

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.

Constraining uncertainties of diazotroph biogeography from nifH gene abundance [PDF]
Limnology and Oceanography, 2022 AbstractMarine diazotrophs fix dinitrogen gas into bioavailable nitrogen that drives the ocean nitrogen cycle; yet, efforts to infer global diazotroph distributions have been limited by a sparsity of observations. In situ measurements of nifH gene abundance (essential for nitrogen fixation) are increasingly being used to inform the biogeography of ...

Nitrogenase gene amplicons from global marine surface waters are dominated by genes of non-cyanobacteria. [PDF]
PLoS ONE, 2011 Cyanobacteria are thought to be the main N(2)-fixing organisms (diazotrophs) in marine pelagic waters, but recent molecular analyses indicate that non-cyanobacterial diazotrophs are also present and active.

In Rhizobium japonicum the nitrogenase genes nifH and nifDK are separated [PDF]
Journal of Bacteriology, 1983 In contrast to Klebsiella pneumoniae or fast-growing Rhizobium species, such as R. meliloti, where the nitrogenase structural genes are clustered in one operon (nifHDK), in slow-growing Rhizobium japonicum 110, nifH and nifDK are on separate operons.

Characterization and analysis of nifH genes from Paenibacillus sabinae T27 [PDF]
Microbiological Research, 2012 Paenibacillus sabinae T27 (CCBAU 10202=DSM 17841) is a gram-positive, spore-forming diazotroph with high nitrogenase activities. Three nifH clusters were cloned from P. sabinae T27. Phylogenetic analysis revealed that NifH1, NifH2 and NifH3 cluster with Cyanobacterium. Each of the coding regions of nifH1, nifH2 and nifH3 from P.

The Abundance of the nifH Gene Became Higher and the nifH-Containing Diazotrophic Bacterial Communities Changed During Primary Succession in the Hailuogou Glacier Chronosequence, China. [PDF]
Front Microbiol, 2021 Primary successional ecosystems and the related soil development are often N limited. To date, N2-fixing communities during primary succession in alpine ecosystems have remained underexplored. In this study, we applied quantitative PCR (qPCR) quantitation and targeted amplicon sequencing of nifH in the Hailuogou Glacier foreland to investigate the ...
