Formation of NifA-PII complex represses ammonium-sensitive nitrogen fixation in diazotrophic proteobacteria lacking NifL

Cell Reports
Summary: Biological nitrogen fixation catalyzed by nitrogenase contributes greatly to the global nitrogen cycle. Nitrogenase expression is subject to regulation in response to nitrogen availability.

Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

Environmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

A Phosphorylation‐Dependent Partner‐Switching‐Like Module Regulates a Glycosyltransferase Required for Heterocyst Polysaccharide Layer Formation in Anabaena sp. Strain PCC 7120

Molecular Microbiology, EarlyView.
The glycosyltransferase All4160 is regulated by the reversible phosphorylation of Ser74. The kinase Alr3423 phosphorylates and inactivates All4160, while the SpoIIE‐like phosphatase HenR restores its activity through dephosphorylation. A nonphosphorylatable variant of All4160 bypasses the need for HenR, which demonstrates that a phosphorylation ...

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

mLife
Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Two distinct ferredoxins are essential for nitrogen fixation by the iron nitrogenase in Rhodobacter capsulatus

mBio
Nitrogenases are the only enzymes able to fix gaseous nitrogen into bioavailable ammonia and hence are essential for sustaining life. Catalysis by nitrogenases requires both a large amount of ATP and electrons donated by strongly reducing ferredoxins or ...

Nonuniform temperature and light relationships of moss‐associated nitrogen fixation across climates

New Phytologist, EarlyView.
Light, moisture, and temperature response of nitrogen fixation in moss–cyanobacteria associations across five climatically contrasting ecosystems. Responses of nitrogen fixation in moss–cyanobacteria associations to light (μmol photons m−2 s−1), moss relative water content (%), and temperature (°C) across five climatically contrasting ecosystems ...

GmDOF3.1‐GmCPX Module Regulates Nodulation and Nitrogen Fixation Abilities in Soybean

Plant Biotechnology Journal, EarlyView.
ABSTRACT Soybean nodule nitrogen fixation is very important, which can provide a large amount of nitrogen supply for its own growth and that of other crops, but the mechanism is largely unclear. In the present study, a coproporphyrinogen oxidase gene, GmCPX, was identified to facilitate soybean nodulation and nitrogen‐fixation under the regulation of ...

Rhizobial Symbiosis Enhances Salinity Tolerance in Legumes Through Coordinated Physiological and Molecular Responses: Evidence From Common Vetch and Pea

Plant, Cell &Environment, EarlyView.
ABSTRACT Soil salinisation severely constrains crop production. Legumes rely on rhizobial symbiosis for sustainable nitrogen acquisition. Although salinity is known to impair nodulation and nitrogen fixation, how symbiosis influences plant tolerance to salt stress remains unclear.

Advancing Thermotolerance in Beans: Integrating Physiology, Genomics, and Breeding for Climate Adaptation

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...
