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 ...

Molecular phylogeny, population genetics, and evolution of heterocystous cyanobacteria using nifH gene sequences

Protoplasma, 2012
In order to assess phylogeny, population genetics, and approximation of future course of cyanobacterial evolution based on nifH gene sequences, 41 heterocystous cyanobacterial strains collected from all over India have been used in the present study. NifH gene sequence analysis data confirm that the heterocystous cyanobacteria are monophyletic while ...

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

Molecular Genetics and Genomics, 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 ...

Two seasons’ study on nifH gene expression and nitrogen fixation by diazotrophic endophytes in sugarcane (Saccharum spp. hybrids): expression of nifH genes similar to those of rhizobia

Plant and Soil, 2010
To explore the presence and expression of the nifH gene of diazotrophic endophytes in sugarcane (Saccharum spp. hybrids) cv. NiF8, we conducted pot experiments for two seasons in a glasshouse from 10 June to 17 September (high temperature and long days) in 2005 and 1 September to 9 December (low temperature and short days) in 2006.

Diversity of Frankia in soil assessed by Illumina sequencing of nifH gene fragments.

Systematic and Applied Microbiology, 2016
Targeted Illumina sequencing of nitrogenase reductase (nifH) gene fragments and analyses of pair-end reads through a modified QIIME pipeline were used to assess the diversity of the actinomyceteous genus Frankia in three soils. Soils were vegetated with host or non-host plants, and included locations in Illinois (ABA, host), Colorado (CoMt, non-host ...

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.
