Acetylene Semi‐Hydrogenation by Photocatalysis

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Photocatalytic acetylene semi‐hydrogenation is an emerging light‐driven route to polymer‐grade ethylene, offering a mild alternative to energy‐intensive thermocatalysis. By replacing H2 co‐feed with water or other proton sources, these systems can achieve high selectivity under ambient conditions.

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 ...

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.

Lotus japonicus CLV1‐Like Receptor HAR1 Promotes Nitrogen Utilisation and Growth Under Non‐Symbiotic Conditions

Plant, Cell &Environment, EarlyView.
ABSTRACT Legumes establish mutualistic symbiosis with nitrogen (N)‐fixing bacteria, which allows them to utilise atmospheric N2. Because the maintenance of symbiosis requires abundant carbon (C) sources, legumes regulate the balance between carbon consumption and nitrogen acquisition by systemically controlling the nodule number through CLAVATA1 (CLV1)‐

Surface Ligand Engineering in Quantum Dot Photocatalysis: Mechanisms, Design Principles, and Applications

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.
Surface ligands govern quantum dot photocatalysis through thermodynamic band‐edge tuning, kinetic charge‐transfer regulation, and microenvironmental control. Rational ligand engineering, using short‐chain, inorganic, conjugated, or dual‐ligand systems, enables efficient solar fuel production, selective organic transformations, environmental remediation,

The Dynamics of Seed‐Derived Molybdenum Following Seed Priming in Faba Bean (Vicia faba L.) and Impact on Nitrogen Accumulation

Legume Science, Volume 8, Issue 4, December 2026.
ABSTRACT Molybdenum (Mo) is required for biological nitrogen fixation because it forms part of the FeMo cofactor of nitrogenase. Seed priming has been shown to increase BNF in other legumes, but its effectiveness has not been tested in faba bean (Vicia faba L.).

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.

A Gas Chromatography‐Based Workflow Leads to the Detection of Hydrogenase Activity in Native Bacteria

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
A standardized gas chromatography–based workflow enables direct functional screening of hydrogenase activity in crude membrane and lysate fractions from native bacteria. Without purification or heterologous expression, hydrogen oxidation is detected across phylogenetically diverse organisms, highlighting the value of activity‐based screening for ...

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 ...
