Agrichemical losses are a severe threat to the ecological environment. Additionally, some agrichemical compounds contain abundant salt, which increases instability of formulations, leading lower utilization and soil hardening. Fortunately, biological amphiphilic emulsifier sodium deoxycholate alleviates these problems by forming stable Janus core–shell emulsions through salinity-driven interfacial self-assembly. According behavior, dilational rheology, molecular dynamics simulations, Janus-emulsion molecules more closely arranged than traditional-emulsion generate an oil–water film that transforms into gel film. In addition, at same spray volume, deposition area emulsion increased 37.70% compared with traditional emulsion. Owing topology effect deformation, adheres rice micropapillae, achieving better flush resistance. Meanwhile, based on response stimulation carbon dioxide (CO2), lost can form rigid shell for inhibiting release pesticides metal ions from harming soil. The pyraclostrobin rate decreased 50.89% 4 h after was exposed CO2.

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.

ACS Nano, Год журнала: 2024, Номер 18(22), С. 14276 - 14289

Опубликована: Май 23, 2024

The frequency, duration, and intensity of heat waves (HWs) within terrestrial ecosystems are increasing, posing potential risks to agricultural production. Cerium dioxide nanoparticles (CeO2 NPs) garnering increasing attention in the field agriculture because their enhance photosynthesis improve stress tolerance. In present study, CeO2 NPs decreased grain yield, protein content, amino acid content by 16.2, 23.9, 10.4%, respectively, under HW conditions. Individually, neither nor HWs alone negatively affected rice production or triggered stomatal closure. However, conditions, conductance net photosynthetic rate 67.6 33.5%, respectively. Moreover, closure presence reactive oxygen species (ROS) accumulation (increased 32.3–57.1%), resulting chloroplast distortion reduced photosystem II activity (decreased 9.4–36.4%). Metabolic, transcriptomic, quantitative real-time polymerase chain reaction (qRT-PCR) analyses revealed that, activated a pathway mediated abscisic (ABA) ROS regulating gene expression (PP2C, NCED4, HPCA1, RBOHD were upregulated, while CYP707A ALMT9 downregulated) metabolite levels (the γ-aminobutyric (GABA) increased that gallic decreased). These findings elucidate mechanism underlying yield nutritional losses induced thus highlight threat posed during HWs.
