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.

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.

Comparison ofnifHGene Pools in Soils and Soil Microenvironments with Contrasting Properties [PDF]
Applied and Environmental Microbiology, 2001 ABSTRACTThe similarities and differences in the structures of thenifHgene pools of six different soils (Montrond, LCSA-p, Vernon, Dombes, LCSA-c, and Thysse Kaymor) and five soil fractions extracted from LCSA-c were studied. Bacterial DNA was directly extracted from the soils, and a region of thenifHgene was amplified by PCR and analyzed by restriction.

Diverse and Novel nifH and nifH -Like Gene Sequences in the Deep-Sea Methane Seep Sediments of the Okhotsk Sea [PDF]
Applied and Environmental Microbiology, 2009 ABSTRACT Diverse nifH and nifH -like gene sequences were obtained from the deep-sea surface sediments of the methane hydrate-bearing Okhotsk Sea. Some sequences formed novel families of the NifH or NifH-like proteins, of currently unresolved bacterial or archaeal origin.
