Biogenic Iron Oxide Nanoparticles Confer Induced Pre‐sowing Drought Tolerance in Glycine max via Enhanced Soil‐Plant Physiological Responses

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT Drought stress severely affects soybean (Glycine max L.) growth and productivity by disrupting physiological and metabolic processes. This study evaluated the potential of biogenic iron oxide nanoparticles green synthesised using Pistacia khinjuk L. leaf extract to improve soybean tolerance to water deficit.

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

Ecological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Removal of Photosystem I Subunit PsaE Leads to Photosynthetic Hydrogen Production in a Cyanobacterial PsaF‐HoxYH Fusion Strain

Plant, Cell &Environment, Volume 49, Issue 9, Page 6850-6858, September 2026.
ABSTRACT Photosynthetic hydrogen (photoH2) production is a promising approach for the utilisation of solar energy. Fusion of a hydrogenase (H2ase) to photosystem I (PSI) provides a direct light‐driven route for photoH2 generation. We established the lateral transmembrane subunit PsaF of PSI as a new fusion partner for the NiFe‐hydrogenase (HoxYH) in ...

From o‐Phenylenediamine to Flavin Derivatives: A Potential Prebiotic Carbon Skeleton Expansion With Formaldehyde, Cyanide, and CO2

Advanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.
A Strecker‐type reaction of aromatic ortho‐diamines with various aldehydes and cyanide assembles the bicyclic amidine core of flavin‐derived heterocycles under mild conditions. Subsequent oxidation, radical or photochemical cyanation, carboxylation with CO2, and CO2‐mediated cyclization build the three‐ring alloxazine scaffold. This sequence provides a

Improving Activity and Stability of Candida boidinii Formate Dehydrogenase Through Rational Active Site Engineering

ChemBioChem, Volume 27, Issue 15, 14 August 2026.
In search of improved biocatalysts for the NADH cofactor recycling in synthetic reductive biotransformations, C. boidinii formate dehydrogenase is the subject of a rational protein engineering approach. The study delivers an enzyme variant with improved specific activities and a more desirable pH and temperature profile, which shows promising ...

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

FEBS Letters, Volume 600, Issue 15, Page 2129-2142, August 2026.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Characterization of a Unique Pair of Ferredoxin and Ferredoxin NADP⁺ Reductase Isoforms That Operates in Non-Photosynthetic Glandular Trichomes

Plants
Our recent investigations indicated that isoforms of ferredoxin (Fd) and ferredoxin NADP+ reductase (FNR) play essential roles for the reductive steps of the 2C-methyl-D-erythritol 4-phosphate (MEP) pathway of terpenoid biosynthesis in peppermint ...

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

FEBS Open Bio, Volume 16, Issue 8, Page 1491-1500, August 2026.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

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 ...
