NifH- Harboring Bacterial Community Composition Across an Alaskan Permafrost Thaw Gradient
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

Plant Growth Promotion Diversity in Switchgrass-Colonizing, Diazotrophic Endophytes
Endophytic nitrogen-fixing (diazotrophic) bacteria are essential members of the microbiome of switchgrass (Panicum virgatum), considered to be an important commodity crop in bioenergy production.

Endophytic bacteria are nearly ubiquitously present in the internal tissues of plants, and some endophytes can promote plant growth. In this study, we sampled the roots of four ancestral species of sugarcane (two genotypes per species) and two sugarcane ...

The N2 fixing cyanobacterium Trichodesmium is a critically important organism in oligotrophic marine ecosystems, supplying βnewβ nitrogen (N) to the otherwise N-poor tropical and subtropical regions where it occurs.

Phyllosphere of Cotton as a Habitat for Diazotrophic Microorganisms [PDF]
Positive nitrogenase activities ranging from 0.18 to 0.78 nmol of C 2 H 4 cm β2 h β1 were detected on the leaf surfaces of different varieties of cotton ( Gossypium hirsutum L. and G. herbaceum L.)

Mesozooplankton Graze on Cyanobacteria in the Amazon River Plume and Western Tropical North Atlantic
Diazotrophic cyanobacteria, those capable of fixing di-nitrogen (N2), are considered one of the major sources of new nitrogen (N) in the oligotrophic tropical ocean, but direct incorporation of diazotrophic N into food webs has not been fully examined ...

Phyllosphere exudates create specialized microhabitats that shape microbial community diversity. We explored the microbiome associated with two sorghum phyllosphere exudates, the epicuticular wax and aerial root mucilage.

Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

Observed and modeled diazotroph nifH abundances in the global ocean
We supplemented the dataset presented in Luo et al. (2012) "Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates" with measurements of nifH genes using qPCR from 17 additional publications.
