Anthropogenic impact on diazotrophic diversity in the mangrove rhizosphere revealed by nifH pyrosequencing [PDF]
, 2015 Diazotrophs in the mangrove rhizosphere play a major role in providing new nitrogen to the mangrove ecosystem and their composition and activity are strongly influenced by anthropogenic activity and ecological conditions.

Plant-Mediated Changes in Soil N-Cycling Genes during Revegetation of Copper Mine Tailings
Frontiers in Environmental Science, 2017 Nitrogen limitation represents a major bottleneck during the revegetation of mine tailings. However, controls over key nitrogen-cycling genes in rhizospheric soils under differential vegetation management remain poorly understood.

Development of a PCR assay for the detection of nifH and nifD genes in indigenous photosynthetic bacteria. [PDF]
, 2009 Molybdenum (Mo) nitrogenases consist of two components: dinitrogenase reductase (encoded by nifH) and the dinitrogenase or MoFe protein (encoded by nifDK). Nitrogenase enzyme of photosynthetic bacteria is responsible for hydrogen production.

Expression of the Klebsiella pneumoniae nifH gene in Saccharomyces cerevisiae
Enzyme and Microbial Technology, 1987 Dinitrogenase reductase, a component of a complex and highly regulated prokaryotic enzyme, nitrogenase, is expressed in the eukaryote Saccharomyces cerevisiae. A plasmid pH-ADH-1 was constructed that directs the expression of the Klebsiella pneumoniae nifH gene, encoding dinitrogenase reductase, from the yeast alcohol dehydrogenase I promoter.

A novel strain D5 isolated from Acacia confusa. [PDF]
PLoS ONE, 2012 We isolated a novel strain D5 from nodules of Acacia confusa. Under strict sterile conditions the strain could successfully nodulate Acacia confusa, A. crassicarpa and A.

Royal Society Open Science, 2021 Recent research suggests that nitrogen (N) cycling microbes are important for coral holobiont functioning. In particular, coral holobionts may acquire bioavailable N via prokaryotic dinitrogen (N2) fixation or remove excess N via denitrification activity.

nifH pyrosequencing reveals the potential for location-specific soil chemistry to influence N2-fixing community dynamics [PDF]
, 2014 A dataset of 87 020 nifH reads and 16 782 unique nifH protein sequences obtained over 2 years from four locations across a gradient of agricultural soil types in Argentina were analysed to provide a detailed and comprehensive picture of the diversity ...

mLife, EarlyView.Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.
