Global marine metagenomics reveals the functional diversity and ecological adaptations of diazotrophs across marine ecosystems

Communications Earth & Environment
Biological nitrogen fixation by diazotrophs is vital for nitrogen supply and marine productivity. Despite extensive documentation of diverse diazotrophs, their functional diversity and adaptive strategies across ecosystems remain largely underexplored ...

Multiomic Approaches Reveal Hormonal Modulation and Nitrogen Uptake and Assimilation in the Initial Growth of Maize Inoculated with Herbaspirillum seropedicae

Plants, 2022
Herbaspirillum seropedicae is an endophytic bacterium that can fix nitrogen and synthesize phytohormones, which can lead to a plant growth-promoting effect when used as a microbial inoculant.

Virocell Necromass Provides Limited Plant Nitrogen and Elicits Rhizosphere Metabolites That Affect Phage Dynamics

Plant, Cell &Environment, EarlyView.
ABSTRACT Bacteriophages impact soil bacteria through lysis, altering the availability of organic carbon and plant nutrients. However, the magnitude of nutrient uptake by plants from lysed bacteria remains unknown, partly because this process is challenging to investigate in the field.

Ecology of marine diazotrophs: past, present, and future [PDF]

, 2021
Nitrogen (N) is an essential nutrient and is often a limiting factor for primary production and carbon uptake. Classically, cyanobacterial diazotrophs were thought to be the major N2 fixers in the ocean.

Diazotroph Genomes and Their Seasonal Dynamics in a Stratified Humic Bog Lake

Frontiers in Microbiology, 2020
Aquatic N-fixation is generally associated with the growth and mass development of Cyanobacteria in nitrogen-deprived photic zones. However, sequenced genomes and environmental surveys suggest active aquatic N-fixation also by many non-cyanobacterial ...

Exploring the diversity of pyruvate:ferredoxin oxidoreductases

Protein Science, Volume 35, Issue 12, December 2026.
Abstract Pyruvate:ferredoxin oxidoreductases (PFORs) are key enzymes in the anaerobic metabolism of numerous diverse organisms. Their significance extends far beyond the oxidative decarboxylation of pyruvate, their canonical reaction. PFORs support diverse physiological roles, including fermentation and carbon assimilation, and have been integrated ...

Trophic highways and dead ends: Algal traits regulate nutrient flux and energy transfer in stream food webs

Ecology, Volume 107, Issue 11, November 2026.
Abstract Primary producers supply energy to ecosystems, but their traits determine whether fixed carbon (C) and nutrients are retained or transferred to consumers. In nitrogen (N)‐limited rivers, N fixation can provide a critical nutrient input, yet its role in supporting food webs remains poorly constrained.
