Lipid peroxidation-generated nonanedioic acid (also called azelaic acid, AZA), a 9-carbon dicarboxylic acid (DCA), primes plant defense responses. Here, we report that, along with AZA, a 7-carbon DCA, heptanedioic acid (also called pimelic acid; PIM), is also generated in plants experiencing pathogen and photoinhibitory (high light/cold) stresses. The exogenous foliar application of these DCAs induced basal defense against bacterial and fungal pathogens, with PIM showing a greater effect. Assessment against viral pathogens revealed systemic implications of these DCAs. Interestingly, AZA-primed defense penalized growth, while PIM treatment primed both defense elicitation and growth promotion. Induced systemic growth promotion and stress resilience in different plants upon foliar spray at the cotyledonary leaf stage present PIM as a promising and broad-spectrum biostimulant that could enhance agricultural productivity.

Mango is traditionally classified as a climacteric fruit, in which ethylene and abscisic acid (ABA) play central roles in ripening. Mango fruit is cultivated only in tropical and some subtropical regions, therefore, to meet global demand, cold storage is widely used during transport, followed by a ripening period. This study evaluated the effects of simulated commercial transit cold storage (9 °C, > 85% relative humidity [RH]) used during the sea freight supply chain from the Southern hemisphere to the UK, by comparing the two main mango fruit cultivars (‘Keitt’ and ‘Kent’) imported into the UK market. Fruit were ripened with and without prior cold storage (control) and the synthesis and catabolism of key ripening regulators (ABA and its metabolites) as well as associated changes in quality attributes (internal colour, firmness, individual sugar content) were investigated. Cold storage delayed firmness loss, extending the postharvest life from 10 to 12 days to 29 days. ABA accumulated throughout ripening in control fruit but was depleted in cold-stored fruit for both cultivars, indicating its central role in mango ripening; cold storage fundamentally altered ABA dynamics by suppressing accumulation and modifying spatial distribution and conjugation patterns in a cultivar and pulp dependent manner. Additionally, sugar metabolism was altered, likely affecting taste, and meaning that, in cold-stored fruit, sugar content no longer correlated with total soluble solids (TSS). These findings highlight ABA as a potential target for postharvest management and underscore the need for integrated quality indices beyond TSS to improve fruit evaluation and reduce losses in global supply chains. • Cold storage depletes abscisic acid and disrupts normal ripening progression. • Sugar metabolism is altered, decoupling sugars from soluble solids content. • No chilling injury symptoms were observed after storage at 9 °C.

Selenium (Se) deficiency is a widespread nutritional problem. Agronomic biofortification of microgreens through seed nutripriming is a promising approach to enhance Se intake. Microgreens, comprising nutrient-dense foods that can be produced year-round, are ideal targets for biofortification and may help alleviate malnutrition. This study evaluated the effects of Se nutripriming on germination, growth performance, chemical composition and antioxidant properties of pea (Pisum sativum L.) microgreens. Nutripriming significantly increased seed Se content, with the 100 μm-12-h Se treatment resulting in a four-fold accumulation compared to controls, at the same time as preserving membrane integrity. Microgreens from primed seeds exhibited enhanced Se translocation to aerial tissues and an improved mineral profile. Short-term treatments (6 h) increased glucose and oxalic acid levels, whereas prolonged priming (12 h) favored sucrose accumulation. However, this 12-h duration significantly reduced the emergence rate and aerial biomass yield. The optimal antioxidant profile, characterized by the highest total phenolic content and strongest inhibition of lipid peroxidation, was achieved with the 50 μm-12-h Se treatment. Se nutripriming enhanced the nutritional quality of pea microgreens but revealed a critical trade-off: although 12-h priming maximized Se uptake and antioxidant properties, it severely reduced agronomic production. Conversely, 6-h priming promoted better biomass yield, although germination remained lower than in the NP control. Therefore, optimizing priming duration is essential to balance the biofortification benefits with overall crop productivity. © 2026 The Author(s).

Here, we report a one-pot tandem catalytic system that integrates CO2 hydrogenation to CH3O* intermediates with their in situ esterification using dicarboxylic acids, directly yielding dimethyl esters (e.g., polyester monomers for polyethylene terephthalate (PET) manufacturing) as final products with >99% selectivity. This system is enabled by a metal-organic framework (MOF)-derived catalyst featuring carbon-nanoconfined atomic Cuδ+ sites anchored on ca. 1.8nm tetragonal ZrO2 nanoparticles (CuSA-ZrO2-C), which achieves an efficient CO2 conversion of 28% at a reduced temperature of 150°C in a batch reactor. The process delivers a high space-time yield of esters, corresponding to a CO2 conversion efficiency of 158.6gCO2gcat -1h-1. Mechanistic studies gained from control experiments, in situ time-resolved diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), and density functional theory (DFT) calculations reveal that a tripartite synergy among atomic Cuδ+ sites, oxygen vacancies, and surface hydroxyls on t-ZrO2 nanoparticles stabilizes key intermediates (*CO, *COOH, *HCOO-, *CHO) and opens a hydroxyl mediated pathway. This pathway redirects the typically poisoning *CO species toward *CHO, thereby circumventing the persistent *CO poisoning challenge. This work presents an atomic-level design strategy that simultaneously advances low-temperature CO2 hydrogenation and intermediate valorization, establishing an integrated and carbon-efficient route from CO2 to polymer feedstocks.
