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]
Frontiers in Microbiology, 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 ...

Nodulation of Shepherdia ×utahensis ‘Torrey’ and the Diversity of Symbiotic Frankia Strains
HortScience, 2021 Shepherdia ×utahensis ‘Torrey’ (hybrid buffaloberry) is an actinorhizal plant that can form symbiotic nodules with the actinobacterial genus Frankia. However, little research has been conducted to investigate the presence of Frankia in their nodules and ...

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 ...

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.

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.

Diverse and Novel nifH and nifH -Like Gene Sequences in the Deep-Sea Methane Seep Sediments of the Okhotsk Sea [PDF]
Applied and Environmental Microbiology, 2009 ABSTRACT Diverse nifH and nifH -like gene sequences were obtained from the deep-sea surface sediments of the methane hydrate-bearing Okhotsk Sea. Some sequences formed novel families of the NifH or NifH-like proteins, of currently unresolved bacterial or archaeal origin.

High diversity of nitrogen-fixing bacteria in the upper reaches of the Heihe River, northwestern China [PDF]
Biogeosciences, 2013 Vegetation plays a key role in water conservation in the southern Qilian Mountains (northwestern China), located in the upper reaches of the Heihe River. Nitrogen-fixing bacteria are crucial for the protection of the nitrogen supply for vegetation in the

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.
