A comprehensive evaluation of PCR primers to amplify the nifH gene of nitrogenase. [PDF]

open access: yesPLoS 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

Genetic analysis of the NifM dependence of the nitrogenase iron proteins [PDF]

open access: yesmBio
NifH maturation in certain diazotrophic bacteria depends on NifM, a protein with a PpiC-isomerase domain. Intriguingly, the putative proline substrate for NifM is present in NifH proteins from strains lacking nifM, raising questions regarding the actual ...

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

open access: yesFrontiers 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 ...

NifH-Harboring Bacterial Community Composition across an Alaskan Permafrost Thaw Gradient

open access: yesFrontiers 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

Biotechnological potential of Pectobacterium sp. endophyte on the growth of soy and bean plants

open access: yesRevista Principia, 2023
Fertilizers and chemical pesticides supply plants’ nutritional requirements and protect them against pathogens. However, they may cause harm to the environment. Pectobacterium sp.

Undervalued Pseudo-nifH Sequences in Public Databases Distort Metagenomic Insights into Biological Nitrogen Fixers

open access: yesmSphere, 2021
Nitrogen fixation, a distinct process incorporating the inactive atmospheric nitrogen into the active biological processes, has been a major topic in biological and geochemical studies.

Analysis of Nitrogenase Fe Protein Activity in Transplastomic Tobacco

open access: yesFrontiers in Agronomy, 2021
Integration of prokaryotic nitrogen fixation (nif) genes into the plastid genome for expression of functional nitrogenase components could render plants capable of assimilating atmospheric N2 making their crops less dependent of nitrogen fertilizers. The

Co-expression of nitrogenase proteins in cotton (Gossypium hirsutum L.).

open access: yesPLoS ONE, 2023
Chemical nitrogen fertilizer can maintain crop productivity, but overuse of chemical nitrogen fertilizers leads to economic costs and environmental pollution.

Assembly of nitrogenase biosynthetic pathway in Saccharomyces cerevisiae by using polyprotein strategy

open access: yesFrontiers in Microbiology, 2023
Nitrogenase in some bacteria and archaea catalyzes conversion of N2 to ammonia. To reconstitute a nitrogenase biosynthetic pathway in a eukaryotic host is still a challenge, since synthesis of nitrogenase requires a large number of nif (nitrogen fixation)

Widespread Distribution and Expression of Gamma A (UMB), an Uncultured, Diazotrophic, γ-Proteobacterial nifH Phylotype. [PDF]

open access: yesPLoS ONE, 2015
Marine dinitrogen (N2) fixation studies have focused nearly exclusively on cyanobacterial diazotrophs; however γ-proteobacteria are an abundant component of the marine community and have been largely overlooked until recently.
