Environmental forcing of nitrogen fixation in the eastern tropical and sub-tropical North Atlantic Ocean. [PDF]
PLoS ONE, 2011 During the winter of 2006 we measured nifH gene abundances, dinitrogen (N(2)) fixation rates and carbon fixation rates in the eastern tropical and sub-tropical North Atlantic Ocean.

Frontiers in Microbiology, 2021 Elevated atmospheric CO2 (eCO2) results in plant growth and N limitation, yet how root-associated nitrogen-fixing bacterial communities respond to increasing atmospheric CO2 and nitrogen fertilization (eN) during the growth stages of rice is unclear ...

Microbiome of Trichodesmium Colonies from the North Pacific Subtropical Gyre
Frontiers in Microbiology, 2017 Filamentous diazotrophic Cyanobacteria of the genus Trichodesmium, often found in colonial form, provide an important source of new nitrogen to tropical and subtropical marine ecosystems.

Frontiers in Microbiology, 2012 Biological soil crusts (biocrusts), which supply significant amounts of fixed nitrogen into terrestrial ecosystems worldwide (~33 Tg y-1), are likely to respond to changes in temperature and precipitation associated with climate change.

Nucleotide sequence of a cyanobacterial nifH gene coding for nitrogenase reductase [PDF]
Proceedings of the National Academy of Sciences, 1980 The nucleotide sequence of nifH , the structural gene for nitrogenase reductase (component II or Fe protein of nitrogenase) from the cyanobacterium Anabaena 7120 has been determined. Also reported are 194 bases of the 5′-flanking sequence and 170 bases of the 3′-flanking sequence.

Possible association of diazotrophs with marine zooplankton in the Pacific Ocean
MicrobiologyOpen, 2016 Dinitrogen fixation, the biological reduction in N2 gas to ammonia contributes to the supply of new nitrogen in the surface ocean. To understand the diversity and abundance of potentially diazotrophic (N2 fixing) microorganisms associated with marine ...

Genetics in methanogens: transposon insertion mutagenesis of a Methanococcus maripaludis nifH gene [PDF]
Journal of Bacteriology, 1995 We designed a transposon insertion mutagenesis system for Methanococcus species and used it to make mutations in and around a nifH gene in Methanococcus maripaludis. The transposon Mudpur was constructed with a gene for puromycin resistance that is expressed and selectable in Methanococcus species. A 15.6-kb nifH region from M.

Diversity pattern of nitrogen fixing microbes in nodules of Trifolium arvense (L.) at different initial stages of ecosystem development [PDF]
Biogeosciences, 2013 Legumes can be considered as pioneer plants during ecosystem development, as they form a symbiosis with different nitrogen fixing rhizobia species, which enable the plants to grow on soils with low available nitrogen content.
