Expression of nifH genes by diazotrophic bacteria in the rhizosphere of short form Spartina alterniflora [PDF]

FEMS Microbiology Ecology, 2003
Abstract A diverse assemblage of diazotrophic bacteria exists in the rhizosphere of the smooth cordgrass, Spartina alterniflora, but the taxa actively involved in nitrogen fixation have not been determined. In order to identify the diazotrophs that were actively expressing nifH, the gene encoding the nitrogenase iron protein, mRNA was extracted from ...

Impact Crater Hydrothermal Systems Support Rapid Microbial Enrichment and Diverse Metabolic Potential

Geobiology, Volume 24, Issue 6, November/December 2026.
ABSTRACT Impact crater hydrothermal systems, formed after asteroid and comet impacts, have been proposed as promising habitats for life on early Earth and as key targets in the search for life on planetary bodies such as Mars, since they provide liquid water and active geochemical turnover.

Water mass dynamics drive nitrogen fixation rates and diazotroph community composition in the coastal ocean

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Although significant N2 fixation rates (NFRs) have been observed throughout mid‐Atlantic coastal waters, studies have been limited in their temporal coverage, and the methods used to detect nitrogen fixers (diazotrophs) and their findings have varied.

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.

Coverage of the nifH gene by sequences and primers in the nifH database.

, 2012
The number of sequences in the nifH database is depicted in relation to alignment position along the gene. Alignment positions are referenced to the nifH nucleotide position from Azotobacter vinelandii (Genbank ACCN# M20568).

Restoring soil health from dredged sediments through electrokinetic remediation for zucchini cultivation

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‐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.

A dual role of phycoerythrin in the nitrogen‐fixing cyanobacterium Crocosphaera watsonii: From light‐harvesting to nitrogen reservoir

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.
