Sulfur‐Rich μ‐O Diiron Catalyst for Electrochemical Hydrogen Production

European Journal of Inorganic Chemistry, Volume 29, Issue 8, 10 March 2026.
A diferric μ‐oxido complex supported by a sulfur‐rich scaffold acts as a proton‐reduction electrocatalyst for H2 production via a μ‐hydroxido species. An aminodithiophenolate scaffold with an NS2 donor set supports diiron complex formation. The diferrous precursor activates O2, giving rise to a diferric μ‐oxido species, which acts as a proton‐reduction

The Hemoglobin Bjgb From Bradyrhizobium diazoefficiens Controls NO Homeostasis in Soybean Nodules to Protect Symbiotic Nitrogen Fixation

Frontiers in Microbiology, 2020
Legume-rhizobia symbiotic associations have beneficial effects on food security and nutrition, health and climate change. Hypoxia induced by flooding produces nitric oxide (NO) in nodules from soybean plants cultivated in nitrate-containing soils.

Analysis of nifH-RNA reveals phylotypes related to Geobacter and Cyanobacteria as important functional components of the N2-fixing community depending on depth and agricultural use of soil [PDF]

, 2017
In this survey, a total of 80 787 reads and 28 171 unique NifH protein sequences were retrieved from soil RNA. This dataset extends our knowledge about the structure and diversity of the functional diazotrophic communities in agricultural soils from ...

A Synthetic Biology Workflow Reveals Variation in Processing and Solubility of Nitrogenase Proteins Targeted to Plant Mitochondria, and Differing Tolerance of Targeting Sequences in a Bacterial Nitrogenase Assay

Frontiers in Plant Science, 2020
While industrial nitrogen fertilizer is intrinsic to modern agriculture, it is expensive and environmentally harmful. One approach to reduce fertilizer usage is to engineer the bacterial nitrogenase enzyme complex within plant mitochondria, a location ...

Foliar-applied glyphosate substantially reduced uptake and transport of iron and manganese in sunflower (helianthus annuus L.) plants [PDF]

, 2006
Evidence clearly shows that cationic micronutrients in spray solutions reduce the herbicidal effectiveness of glyphosate for weed control due to the formation of metal-glyphosate complexes.

Temperature controls bryophyte‐associated nitrogen fixation in super‐humid temperate forests in New Zealand

Ecology, Volume 107, Issue 3, March 2026.
Abstract Nitrogen (N) fixation performed by certain prokaryotes (diazotrophs) is a key source of new N in pristine ecosystems. Diazotrophs associate with various plants, including bryophytes—the dominant plant group in northern ecosystems such as boreal forests. There, bryophyte‐associated N2 fixation contribute half of total ecosystem N input. However,

Nodule Initiation Elicited by Noninfective Mutants of \u3cem\u3eRhizobium phaseoli\u3c/em\u3e [PDF]

, 1985
Rhizobium phaseoli CE106, CE110, and CE115, originally derived by transposon mutagenesis (Noel et al., J. Bacteriol. 158:149-155, 1984), induced the formation of uninfected root nodule-like swellings on bean (Phaseolus vulgaris).

Deep-Sea Archaea Fix and Share Nitrogen in Methane-Consuming Microbial Consortia [PDF]

, 2009
Nitrogen-fixing (diazotrophic) microorganisms regulate productivity in diverse ecosystems; however, the identities of diazotrophs are unknown in many oceanic environments. Using single-cell–resolution nanometer secondary ion mass spectrometry images of ^(

Nanocomposite Reduces Volatile and Aqueous Reactive Nitrogen Losses From Soil Compared to Conventional and Alternative Fertilisers

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Reactive nitrogen losses from agriculture contribute substantially to greenhouse gas emissions, water pollution and ecosystem degradation. Controlled‐release fertiliser technologies offer potential solutions, yet few comprehensively evaluate performance across multiple nitrogen loss pathways and soil types.
