mBio, 2013 Biological nitrogen fixation is an important component of sustainable soil fertility and a key component of the nitrogen cycle. We used targeted metagenomics to study the nitrogen fixation-capable terrestrial bacterial community by targeting the gene for

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.

Dissolved Organic Matter Impacts Nitrogen Fixation in the Arctic Ocean
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.Abstract Climate change‐driven sea ice loss, increased primary production, and nitrogen depletion are reshaping biogeochemistry in the Arctic Ocean (AO). These changes potentially increase the importance of nitrogen fixation, the conversion of dinitrogen gas into bioavailable ammonium, carried out by microorganisms called diazotrophs.

Nitrogen Fixation Aligns with nifH Abundance and Expression in Two Coral Trophic Functional Groups
Frontiers in Microbiology, 2017 Microbial nitrogen fixation (diazotrophy) is a functional trait widely associated with tropical reef-building (scleractinian) corals. While the integral role of nitrogen fixation in coral nutrient dynamics is recognized, its ecological significance ...

Agronomy Journal, Volume 118, Issue 5, September/October 2026.Abstract Dredged sediments are rich in organic matter and nutrients, but their agricultural reuse is limited by high salinity. Electrokinetic remediation (EKR) can remove salts, yet its effect on overall soil health, including microbial function and plant nutrient dynamics, remains poorly understood.

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.

Microbiome‐mediated plant‐soil feedbacks as a tool for resilient agriculture
iMetaOmics, Volume 3, Issue 3, September 2026.Translating plant‐soil feedbacks (PSFs) into reliable agricultural management requires shifting from input‐dependent practices toward endogenous, process‐driven crop resilience. To bridge this gap, we propose a predictive framework centered on three strategic interventions: engineering the crop holobiont, diversifying the soil habitat, and deploying ...

Warm‐wet transition restructures arid lake microbiomes and functional potential
iMetaOmics, Volume 3, Issue 3, September 2026.This study summarizes how a long‐term warm‐dry to warm‐wet transition restructures microbiomes and functional potential in Lake Bosten, an arid lake in northwestern China. Warm‐wet hydroclimatic change increased water level and hydrological connectivity, while decreasing salinity and total nitrogen.

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.Abstract Unicellular diazotrophic cyanobacteria contribute up to ~50% of marine N2 fixation, and Crocosphaera watsonii, characterized by high phycoerythrin (PE) content, is among one of the key species in tropical and subtropical oceans. Although recent observations have revealed heterogeneous N2 fixation activity within C.
