Constraining uncertainties of diazotroph biogeography from nifH gene abundance [PDF]
Limnology and Oceanography, 2022 Marine 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.

Frontiers in Microbiology, 2018 Diazotrophic microorganisms introduce biologically available nitrogen (N) to the global N cycle through the activity of the nitrogenase enzyme. The genetically conserved dinitrogenase reductase (nifH) gene is phylogenetically distributed across four ...

Dissolved organic matter stimulates N2 fixation and nifH gene expression in Trichodesmium. [PDF]
FEMS Microbiology Letters, 2020 Mixotrophy, the combination of heterotrophic and autotrophic nutrition modes, is emerging as the rule rather than the exception in marine photosynthetic plankton.

Database: the Journal of Biological Databases and Curation, 2014 We describe a nitrogenase gene sequence database that facilitates analysis of the evolution and ecology of nitrogen-fixing organisms. The database contains 32 954 aligned nitrogenase nifH sequences linked to phylogenetic trees and associated sequence ...

Frontiers in Microbiology, 2012 The Tropical North Atlantic (TNAtl) plays a critical role in the marine nitrogen cycle, as it supports high rates of biological nitrogen (N2) fixation, yet it is unclear whether this process is limited by the availability of iron (Fe), phosphate (P) or ...

Leveraging Microbe–Rhizosphere Interactions in Organic Farming Systems: A Route to Sustainable Soybean Production [PDF]
Plant-Environment Interactions, Volume 7, Issue 2, April 2026.ABSTRACT Soybean (Glycine max L.) is a major legume crop of global agricultural significance, and its yield is heavily dependent on the rhizospheric microbes. Conventional farming systems can enhance yields in the short term but often at the expense of soil health and biodiversity. Organic farming systems, by contrast, avoid the use of synthetic inputs

Nucleotide sequence of the R.meliloti nitrogenase reductase (nifH) gene.
Nucleic Acids Research, 1981 The nucleotide sequence of the structural gene (nifH) of nitrogenase reductase (Fe protein) from R.meliloti 41 with its flanking ends is reported. The amino acid sequence of nitrogenase reductase was deduced from the DNA sequence. The predicted R.meliloti nitrogenase reductase protein consists of 297 amino acid residues, has a molecular weight of 32 ...

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.

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.

Biological nitrogen fixation and nifH gene abundance in deadwood of 13 different tree species
Biogeochemistry, 2022 Deadwood is an extremely nitrogen (N) poor plant litter whose decomposition may rely on external N sources. Biological N2 fixation (BNF) by free-living diazotrophs, encoded with the nifH gene, is a potential pathway of N acquisition in deadwood.
