Managing farmlands' heavy metal (HM) pollution is crucial for improving plant growth and ensuring agricultural product safety. While low to medium doses of HM exposure may not directly result in crop reduction, they can lead accumulation plants potential food-chain risks, as well trigger the reactive oxygen species (ROS). Excessive ROS cause oxidative stress irreversible damage cells. Nanozymes, cost-effective stable artificial nanoparticles with enzyme-like activity, have been widely used multiple fields. Over past decade, research has confirmed certain nanozymes' effectiveness systemic immunity during remediation. The activities nanozymes hinge on their physicochemical properties, while biological effects also depend application methods, size, charge, coating, varieties, stages. Therefore, it understand nanozyme-plant interactions resistance mechanisms HMs. This paper comprehensively reviews nanozyme-mediated scavenging across enzymology, metabolomics, proteomics, transcriptomics. It introduces pathways effects, influencing factors, possible prospects. review provide a theoretical framework mitigation along other abiotic stresses agriculture sustainable "precision fertilization" nanozymes.

Soil salinization and alkalization can cause great losses to agricultural production in arid regions. Cotton, a common crop semi-arid regions China, often encounters saline stress alkaline stress. In this study, NaCl (8 g·kg−1), Na2CO3 compound material (an organic polymer material) were mixed with field soil before cotton sowing, the ion content, photosynthetic characteristics, metabolite levels of new leaves analyzed at flowering boll-forming stage, aiming clarify metabolic mechanisms by which regulates cotton’s tolerance The results showed that application led an increase K+/Na+ ratio, stomatal conductance (Gs), efficiency PSII photochemistry (ψPSⅡ), potential activity (Fv/Fo), chlorophyll content (Chla Chlb), as well abundances D-xylonic acid DL-phenylalanine treatments. Additionally, there increases K+ Chla/b net rate (Pn), transpiration (Tr), ψPSⅡ, D-saccharic abundance A correlation analysis pathway revealed mainly regulated characteristics balance through regulating key metabolites when was under or Furthermore, positive impact on stronger than tolerance.

Nano-biochar is a source of blackish carbonaceous material, prerequisite for sustainable crop productivity. By using variety feedstock materials, nanobiochar synthesis can be employed via pyrolysis. Therefore, project was initiated to explore the morpho-physio-biochemical alteration at vegetative stage wheat crops after foliar application suspension (NBS). This investigation conducted Botanical Research Area University Lahore in randomized complete block design (RCBD) arrangement, with four treatments (0, 1, 3, and 5% NBS) by maintaining three replications each treatment "Zincol". Nano biochar above mentioned concentrations were foliarly applied end tillering/beginning leaf sheath elongation seedlings assess morphological changes (root length, shoot number leaves, fresh biomass/plant, dry biomass/plant), physio-biochemical alterations (total free amino acids, total sugars, chlorophyll content, protein, phenols, flavonoids), nutrient uptake (Na, K, Ca, Mg, N, P contents. Our findings indicate that 3% NBS yielded most favorable results across all measured attributes. Furthermore, Treatment-4 (5% specifically improved certain traits, including area, soluble proteins, calcium content. Finally, resulted decrease carotenoid sodium content seedlings.

The extensive development of nanotechnologies has allowed nanoparticles to impact living systems through different pathways. effect single exposure high concentrations silver and copper (50–200 mg/L) on Vaccinium myrtillus L. under field conditions was investigated. Nanoparticle uptake in segments assessed by applying inductively coupled plasma–atomic emission spectroscopy a particle-induced X-ray technique. Copper mainly accumulated the roots leaves, while showed higher affinity for berries. nanoparticles’ effects pigments antioxidant activity plant’s leaves were also evaluated. possible human health risk associated with consumption nanoparticle-contaminated berries assessed. results indicated that contaminated presented low health.

The widespread application of nanoparticles (NPs) in agriculture has not only enhanced the efficiency agrochemical use but also introduced environmental pollution, potentially impacting human health through absorption and accumulation edible plants. purpose this study was to evaluate toxic effects ecological risks Cu2O (nCu2O) life cycle soybean, provide a theoretical basis for safe NPs agriculture. Soybeans were grown natural soil modified with nCu2O, bulk cuprous oxide (bCu2O) copper sulfate (CuSO4) at concentrations 0, 50, 200, 800 mg/kg. Samples grains from treated soybeans collected flowering, podding, seed-filling stages analysis. results indicated that treatments bCu2O, Cu2+ reduced chlorophyll content soybean leaves, thereby affecting photosynthesis. Significant reductions observed net photosynthetic rate (Pn), transpiration (Tr), stomatal conductance (Gs), quantum yield photosystem II (Y(II)), photochemical quenching (qP), electron transport (ETR) high concentrations. However, toxicity nCu2O photosynthesis recovers as plant grows. Almost all increased levels antioxidant enzymes (SOD, POD, CAT) oxidative stress. In bCu2O treatments, grain protein significantly reduced, while fat water increased. Phosphorus (P) decreased, whereas sulfur (S), potassium (K), magnesium (Mg) calcium (Ca) contents plants followed order > Cu2+, treatment being slightly more than treatment, both treatment. above data had dose-dependent effect, which inhibited growth changed quality
