EndophyticnifHgene diversity in African sweet potato

Canadian Journal of Microbiology, 2003
A cultivation-independent approach was used to identify potentially nitrogen-fixing endophytes in seven sweet potato varieties collected in Uganda and Kenya. Nitrogenase reductase genes (nifH) were amplified by PCR, and amplicons were cloned in Escherichia coli.

Distribution of Extensive nifH Gene Diversity Across Physical Soil Microenvironments

Microbial Ecology, 2006
The diversity of nitrogen-fixing bacteria is well described for aquatic environments; however, terrestrial analyses remain mostly biased to rhizobial plant-microbe associations. We maximized the level of resolution for this study through the use of nucleotide sequence information extracted from a series of soil microenvironments, ranging from ...

Quantitative Analysis of nifH Genes and Transcripts from Aquatic Environments

2005
The 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, 1988
Rhizobium 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.

Nucleotide sequence of the gene encoding the nitrogenase iron protein (nifH) of Azospirillum brasilense and identification of a region controlling nifH transcription

Molecular and General Genetics MGG, 1989
The DNA sequence was determined for the Azospirillum brasilense nifH gene and part of the nifD gene. The nifH gene is 885 bp long and encodes 293 amino acid residues. The region upstream of the nifH open reading frame contains a putative promoter whose sequence shows perfect homology with promoters of other diazotrophic bacteria and two putative ...

The cloning and functional characterization of the nifH gene of Rhodospirillum rubrum

Gene, 1990
Dinitrogenase 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, 2004
Nitrogen 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.
