Rhizobium japonicum nitrogenase Fe protein gene (nifH) [PDF]

Journal of Bacteriology, 1984
A 12.1-kilobase PstI fragment from Rhizobium japonicum, which contains homology to both the Klebsiella pneumoniae and the Rhizobium meliloti nifH genes, was cloned into vector pHE3 . The nifH -homologous region was localized on the restriction enzyme cleavage map by Southern blot hybridization experiments. DNA fragments overlapping the R.

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 ...

Exploration of nifH gene through soil metagenomes of the western Indian Himalayas. [PDF]

3 Biotech, 2016
This group has previously highlighted the prevalence of Csp genes from cold Himalayan environments. However, this study has explored the uncultured diazotrophs from metagenomes of western Indian Himalayas. The metagenomic nifH gene clone library was constructed from the Temperate, Subtropical and Tarai soils of Western Himalaya, India followed by ...

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 ...

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

<i>NifH</i> gene amplicon sequencing and metagenomic approaches are complementary in assessing diazotroph diversity. [PDF]

ISME Commun
Abstract Exploring the diversity of diazotrophs is key to understanding their role in supplying fixed nitrogen that supports marine productivity. A nested PCR assay using the universal primer set nifH1-nifH4, which targets the nitrogenase (nifH) gene, is a widely used approach for studying marine diazotrophs by amplicon sequencing ...

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 ...

Nitrogen Fixation Aligns with nifH Abundance and Expression in Two Coral Trophic Functional Groups

Frontiers in Microbiology, 2017
Microbial nitrogen fixation (diazotrophy) is a functional trait widely associated with tropical reef-building (scleractinian) corals. While the integral role of nitrogen fixation in coral nutrient dynamics is recognized, its ecological significance ...

Relative Diazotroph Abundance in Symbiotic Red Sea Corals Decreases With Water Depth

Frontiers in Marine Science, 2019
Microbial dinitrogen (N2) fixation (diazotrophy) is a trait critical for coral holobiont functioning. The contribution of N2 fixation to holobiont nitrogen (N) supply likely depends on the ecological niche of the coral holobiont.
