In the current work, foliar application of selenium nanomaterials (Se0 NMs) suppressed sheath blight in rice (Oryza sativa). The beneficial effects were nanoscale specific and concentration dependent. Specifically, amendment 5 mg/L Se0 NMs decreased disease severity by 68.8% Rhizoctonia solani-infected rice; this level control was 1.57- 2.20-fold greater than that Se ions with equivalent mass a commercially available pesticide (Thifluzamide). Mechanistically, (1) controlled release ability enabled wider safe range bioavailability to NMs, (2) transcriptomic metabolomic analyses demonstrated simultaneously promoted salicylic acid- jasmonic-acid-dependent acquired resistance pathways, antioxidative system, flavonoid biosynthesis. Additionally, improved yield 31.1%, increased nutritional quality 6.4–7.2%, enhanced organic content 44.8%, arsenic cadmium contents 38.7 42.1%, respectively, grains as compared infected controls. Human simulated gastrointestinal tract model results showed bioaccessibility 22.0% As Cd 20.3 13.4%, respectively. These findings demonstrate can serve an effective sustainable strategy increase food security.

To address rising global food demand, the development of sustainable technologies to increase productivity is urgently needed. This study revealed that foliar application zinc oxide nanoparticles (ZnO NPs; 30 80 nm, 0.67 mg/d per plant, 6 d) rice leaves under heatwave (HW) stress increased grain yield and nutritional quality. Compared with HW control, HWs+ZnO group presented increases in yield, protein content, amino acid content 22.1%, 11.8%, 77.5%, respectively. Nanoscale ZnO aggregated on leaf surface interacted molecules. at ambient temperature, treatment dissolution NPs by 25.9% facilitated their translocation mesophyll cells. The Zn existed as both ionic particulate ZnO. conditions nutrient levels (Zn, Mn, Cu, Fe, Mg) 15.8 416.9%, chlorophyll 22.2 24.8%, Rubisco enzyme activity 21.2%, antioxidant 26.7 31.2%. Transcriptomic analyses reversed HW-induced transcriptomic dysregulation, thereby enhancing photosynthesis 74.4%. Additionally, diversity, stability, enrichment beneficial microbial taxa protected phyllosphere community from damage. work elucidates how interact phyllosphere, highlighting potential promote agriculture, especially extreme climate events (e.g., HWs).

Abstract BACKGROUND Citrus canker caused by Xanthomonas citri subsp. (Xcc) is a devastating bacterial disease that reduces citrus yield and quality, posing serious threat to the industry. Several conventional chemicals have been used control canker. However, this approach often leads excessive use of chemical agents, can exacerbate environmental pollution promotes development resistant Xcc. Therefore, there significant interest in efficient environmentally friendly technologies RESULTS In study, water‐soluble ZnO quantum dots (ZnO QDs) were synthesised as an nanopesticide against The results showed antibacterial activity QDs irradiated with visible light [half‐maximal effective concentration (EC 50 ) = 33.18 μg mL −1 ] was ~3.5 times higher than dark‐treated group 114.80 ). induced generation reactive oxygen species (•OH, •O − 2 1 O under irradiation, resulting DNA damage, cytoplasmic destruction, decreased catalase superoxide dismutase activities. Transcription analysis downregulation Xcc genes related ‘biofilms, virulence, adhesion’ ‘DNA transfer’ exposure QDs. More importantly, also promoted growth citrus. CONCLUSION This research provides new insights into photocatalytic mechanisms supports more safer QDs‐based nanopesticides © 2024 Society Chemical Industry.

Abstract BACKGROUND Citrus canker, a bacterial disease caused by Xanthomonas citri subsp. (Xcc), is one of the major threats to citrus industry. Inorganic copper (Cu) formulations such as Bordeaux mixture and Kocide 3000 are currently used control canker; however, they poorly water‐soluble have negligible plant transport, making systemic treatment canker difficult. RESULTS This study synthesized Cu 2 O@His one‐pot self‐assembly 2+ histidine for controlling canker. The results showed that had uniform size distribution (≈2.7 nm) good water solubility. It could disrupt cell membrane Xcc enter into cells destroy DNA, thereby inhibiting growth (half maximal inhibitory concentration = 7.4 μg mL −1 ) production virulence factors Xcc. was attributed its excellent dispersibility reactive oxygen species‐inducing ability. therapeutic efficacy transport were much better than those 3000. Additionally, it remarkable biosafety plants earthworms (lethal 50% >> 40 mg kg ). CONCLUSION provides new, eco‐friendly more efficient option control. © 2025 Society Chemical Industry.
