Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

open access: yesJournal of Integrative Plant Biology, EarlyView.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

Electrocatalytic Nitrate Reduction to Hydroxylamine: Breaking the Activity‐Selectivity Trade‐Off by Designer Bifunctional Metal‐Organic Frameworks

open access: yesAngewandte Chemie, Volume 138, Issue 11, 9 March 2026.
A bifunctional metal‐organic framework (MOF) catalyst with dual active sites is developed for enabling NH2OH electrosynthesis via NitRR with both high selectivity and activity. ABSTRACT Electrocatalytic nitrate reduction reaction (NitRR) offers a promising route for hydroxylamine (NH2OH) synthesis under ambient conditions.

High-valent copper in biomimetic and biological oxidations [PDF]

open access: yes, 2016
A long-standing debate in the Cu-O2 field has revolved around the relevance of the Cu(III) oxidation state in biological redox processes. The proposal of Cu(III) in biology is generally challenged as no spectroscopic or structural evidence exists ...

TaPHL7 Transcription Factor Regulates Utilisation of Nitrogen and Phosphorus in Wheat

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Macronutrients nitrogen and phosphorus are essential for plant growth and development, thus being crucial for the productivity of crops. However, the molecular mechanism regulating the utilisation of nitrogen and phosphorus remains elusive. Here, we show that the wheat (Triticum aestivum L.) transcription factor PHOSPHATE STARVATION RESPONSE ...

Natural Variations in the Activity of Hydroxycinnamoyl Transferases Promote Accumulation of Metabolites Conferring Rice Resistance

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant‐derived secondary metabolites act as regulators of in planta defence. Plant phenylpropanoid metabolic compounds, including final metabolites such as lignin and flavonoids, and a few intermediate metabolites play critical roles in defence.

Drought affects Fe deficiency‐induced responses in a purple durum wheat (Triticum turgidum subsp. durum) genotype

open access: yesPlant Biology, EarlyView.
Combined Fe deficiency and drought in durum wheat trigger interactive responses: drought suppressed root Fe uptake regardless of Fe availability, and both stresses altered phytosiderophore release, ABA level and Fe transporter gene expression, revealing a trade‐off between water and Fe. Abstract Iron (Fe) is essential for plants and humans, with over 2

Rieske Iron–Sulfur Cluster Proteins From an Anaerobic Ammonium Oxidizer Suggest Unusual Energetics in Their Parent Rieske/Cytochrome b Complexes

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 4, Page 905-920, April 2026.
ABSTRACT Anaerobic ammonium‐oxidizing (anammox) bacteria employ a unique, hydrazine‐based pathway to obtain energy from nitrite and ammonium. These organisms possess distinct Rieske/cytochrome b complexes whose precise role in anammox metabolism remains unclear, but which have been proposed to include the generation of NAD(P)H.
