NifH- Harboring Bacterial Community Composition Across an Alaskan Permafrost Thaw Gradient [PDF]

Frontiers in Microbiology, 2016
Since nitrogen (N) is often limiting in permafrost soils, we investigated the N2-fixing genetic potential and the inferred taxa harboring those genes by sequencing nifH gene fragments in samples taken along a permafrost thaw gradient in an Alaskan boreal

Evaluation of Primers Targeting the Diazotroph Functional Gene and Development of NifMAP – A Bioinformatics Pipeline for Analyzing nifH Amplicon Data

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 ...

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.

Phylogenetic study of Aliinostoc species (Cyanobacteria) using pc-igs, nifH and mcy as markers for investigation of horizontal gene transfer

Acta Biologica Slovenica, 2022
Selection of genes that have not been horizontally transferred for prokaryote phylogenetic studies is regarded as a challenging task. Internal transcribed spacer of ribosomal genes (16S–23S ITS), microcystin synthetase genes (mcy), nitrogenase (nifH) and

Network analysis reveals ecological links between N-fixing bacteria and wood-decaying fungi. [PDF]

PLoS ONE, 2014
Nitrogen availability in dead wood is highly restricted and associations with N-fixing bacteria are thought to enable wood-decaying fungi to meet their nitrogen requirements for vegetative and generative growth.

Seasonal and long-term effects of nutrient additions and liming on the nifH gene in cerrado soils under native vegetation

iScience, 2021
Summary: Biological nitrogen fixation (BNF) represents the main input source of N in tropical savannas. BNF could be particularly important for Brazilian savannas (known as Cerrado) that show a highly conservative N cycle.

Understanding the expression dynamics of symbiont rhizobial nifH and nitrogen assimilatory NR and GS genes in dry bean (Phaseolus vulgaris L.) genotypes at various growth stages

Legume Science, 2020
Selection of dry bean (Phaseolus vulgaris L.) cultivars based on their symbiotic nitrogen fixation (SNF) could reduce the fertilizer N requirement. The nifH gene in the bacterial symbiont facilitates the organic N assimilation by N‐assimilatory enzymes ...

A colorimetric method to measure in vitro nitrogenase functionality for engineering nitrogen fixation

Scientific Reports, 2022
Biological nitrogen fixation (BNF) is the reduction of N2 into NH3 in a group of prokaryotes by an extremely O2-sensitive protein complex called nitrogenase. Transfer of the BNF pathway directly into plants, rather than by association with microorganisms,
