Microvirga lupini sp. nov., Microvirga lotononidis sp. nov., and Microvirga zambiensis sp. nov. are Alphaproteobacterial root nodule bacteria that specifically nodulate and fix nitrogen with geographically and taxonomically separate legume hosts [PDF]
, 2012 Strains of Gram-negative, rod-shaped, non-spore-forming bacteria were isolated from nitrogen-fixing nodules of the native legumes Listia angolensis (from Zambia) and Lupinus texensis (from Texas, USA).

Temporal and spatial variability of nifH expression in three filamentous Cyanobacteria in coastal microbial mats [PDF]
, 2010 Cyanobacteria are often the most conspicuous structural part of microbial mats. They are also the only oxygenic phototrophs capable of N2 fixation (diazotrophy).

Nodularia sp. nifH gene transcripts in the Baltic Sea proper [PDF]
Journal of Plankton Research, 2007 While bacterioplankton indisputably control vital biogeochemical paths in the cycling of carbon and nutrients in the world’s oceans, our knowledge about the functional and genetic diversity of bacterioplankton communities is negligible. In this thesis, molecular and more traditional microbiological methods were used to study the specific function of N2-

UNDERSTANDING THE NIFM DEPENDENCE OF NIFH IN AZOTOBACTER VINELANDII:FUNCTIONAL SUBSTITUTION OF NIFH BY A NIFH-CHLL CHIMERIC CONSTRUCT IN A NIFM- STRAIN [PDF]
, 2007 The enzyme nitrogenase catalyzes the energy-dependent reduction of dinitrogen to ammonia via biological nitrogen fixation. Nitrogenase is composed of two metalloproteins known as the molybdenum-iron (MoFe) protein and the iron (Fe) protein.

NifH- Harboring Bacterial Community Composition Across an Alaskan Permafrost Thaw Gradient [PDF]
, 2016 Since nitrogen (N) is often limiting in permafrost soils, we investigated the N2-fixing genetic potential and the inferred taxa harboring those genes by sequencing nifH gene fragments in samples taken along a permafrost thaw gradient in an Alaskan boreal

Development and Testing of a DNA Macroarray To Assess Nitrogenase ( nifH ) Gene Diversity [PDF]
Applied and Environmental Microbiology, 2004 ABSTRACT A DNA macroarray was developed and evaluated for its potential to distinguish variants of the dinitrogenase reductase ( nifH ) gene. Diverse nifH gene fragments amplified from a clone library were spotted onto nylon membranes. Amplified, biotinylated nifH

Rapid annotation of nifH gene sequences using classification and regression trees facilitates environmental functional gene analysis [PDF]
, 2016 The nifH gene is a widely used molecular proxy for studying nitrogen fixation. Phylogenetic classification of nifH gene sequences is an essential step in diazotroph community analysis that requires a fast automated solution due to increasing size of ...
