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

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

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 ...

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

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 ...

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

Contamination of diversenifHandnifH-like DNA into commercial PCR primers [PDF]

open access: yesFEMS Microbiology Letters, 2005
False-positive results due to DNA contamination in PCR reagents have become a big problem in the amplification of small amounts of DNA. Recently, it was revealed that PCR reagents were contaminated with the nifH (dinitrogenase reductase) gene. We found that the PCR primers supplied by some manufacturers contained nifH gene and nifH-like DNA.

Constraining uncertainties of diazotroph biogeography from nifH gene abundance [PDF]

open access: yesLimnology 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 ...

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.
