Quantitative Analysis of nifH Genes and Transcripts from Aquatic Environments
2005The availability of fixed inorganic nitrogen often plays a fundamental role in regulating primary production in both aquatic and terrestrial ecosystems. Because biological nitrogen fixation is an important source of nitrogen in marine environments, the study of N2-fixing microorganisms is of fundamental importance to our understanding of global ...

Transcription analysis of the three nifH genes of Rhizobium phaseoli with gene fusions
Molecular and General Genetics MGG, 1988Rhizobium phaseoli CFN42 possesses three regions containing genes coding for the nitrogenase polypeptides: region a and region b contain copies of the three nitrogenase structural genes nifH, nifD and nifK and region c contains only a nifH gene.

The cloning and functional characterization of the nifH gene of Rhodospirillum rubrum
Gene, 1990Dinitrogenase reductase (the nifH product) from Rhodospirillum rubrum is regulated by a post-translational modification system encoded by draTG. As demonstrated in this report, the cloning, sequencing, and functional characterization of the nifH gene provides a basis for further analysis as well as revealing interesting features of gene organization ...

The nitrogen-fixing gene (nifH) of Rhodopseudomonas palustris: a case of lateral gene transfer?
Microbiology, 2004Nitrogen fixation is catalysed by some photosynthetic bacteria. This paper presents a phylogenetic comparison of a nitrogen fixation gene (nifH) with the aim of elucidating the processes underlying the evolutionary history of Rhodopseudomonas palustris. In the NifH phylogeny, strains of Rps.

In Rhizobium Japonicum the Nifh and Nifdk Genes are Separated
1984We have shown previously that a cloned HindIII restriction fragment from Rhizobium japonicum 3I1b 110 contains the nitrogenase structural genes nifD and nifK (Fig. 1). However, we have not obtained evidence for the existence of the gene for nitrogenase reductase (nifH) adjacent to th nifDK cluster.

Molecular ecology of nifH genes and transcripts in the eastern Mediterranean Sea
Environmental Microbiology, 2007Summary The eastern Mediterranean Sea is one of the most extreme oligotrophic oceanic regions on earth in terms of nutrient concentrations and primary productivity. Nitrogen fixation has been suggested to contribute to the high N : P molar ratios of ∼28:1 found in this region. Surprisingly, no molecular biological

Paenibacillus wenxiniae sp. nov., a nifH gene -harbouring endophytic bacterium isolated from maize
Antonie van Leeuwenhoek, 2015A novel Gram-positive, aerobic, motile, endospore-forming, rod-shaped bacterium, designated 373(T) was isolated from surface-sterilised root tissue of a maize planted in Fangshan District of Beijing, Peopole's Republic of China. A polyphasic taxonomic study was performed on the new isolate.

Molecular Diversity of nifH Genes from Bacteria Associated with High Arctic Dwarf Shrubs
Microbial Ecology, 2006Biological nitrogen fixation is the primary source of new N in terrestrial arctic ecosystems and is fundamental to the long-term productivity of arctic plant communities. Still, relatively little is known about the nitrogen-fixing microbes that inhabit the soils of many dominant vegetation types.
