Diuron [DU; 3-(3,4-dichlorophenyl)-1,1-dimethylurea], a widely used herbicide for weed control, arouses ecological and health risks due to its environment persistence. Our findings revealed that DU at 0.125–2.0 mg L–1 caused oxidative damage to rice. RNA-sequencing profiles disclosed a globally genetic expression landscape of rice under DU treatment. DU mediated downregulated gene encoding photosynthesis and biosynthesis of protein, fatty acid, and carbohydrate. Conversely, it induced the upregulation of numerous genes involved in xenobiotic metabolism, detoxification, and anti-oxidation. Furthermore, 15 DU metabolites produced by metabolic genes were identified, 7 of which include two Phase I-based and 5 Phase II-based derivatives, were reported for the first time. The changes of resistance-related phytohormones, like JA, ABA, and SA, in terms of their contents and molecular-regulated signaling pathways positively responded to DU stress. Our work provides a molecular-scale perspective on the response of rice to DU toxicity and clarifies the biotransformation and degradation fate of DU in rice crops.

The Nd III coordination compounds [Nd(4-pytza) 3 (H 2 O) 2 ]· 2H 2 O (1) and [Nd(4-pytza) 2 (H 2 O) 4 ]Cl·2H 2 O (2) [H4-pytza = 5-(4-pyridyl)tetrazole-2-acetic acid] were synthesized by reactions of K4-pytza and NdCl 3 ·6H 2 O at different pH values. Single crystal X-ray diffraction analysis reveals that 4-pytza ligands in 1 in a μ 1,3 -COO syn-syn or μ 1,1,3 -COO bridging mode coordinate to two central Nd III atoms to

Organophosphorus magnetic molecularly imprinted polymers (OMMIPs) with high adsorption capacities (13.5–83.8 mg g–1) and good applicability were developed for efficient extraction and pre-concentration of multiple organophosphorus pesticides (OPPs) from foodstuffs. The OMMIP-based sample pretreatment coupled with low-temperature plasma ambient ionization mass spectrometry achieved rapid screening for 90 kinds of pesticides at default maximum residue limits of National Standard (GB 2763-2021) in nine types of agro-products. The OMMIP-based liquid chromatography coupled with triple quadrupole mass spectroscopy assay demonstrated rapid magneto-actuated isolation, efficient removal of matrix interference, and reduced signal suppression, resulting in a short detection time (30 min), compliant recoveries (60.1–127.5%), low detection limits (0.0001–0.073 μg g–1), and simultaneous quantification of multi-pesticides. The yolk–shell-structured OMMIPs (Fe3O4@mTiO2@MIPs) demonstrated additional benefits of excellent ultraviolet light-driven catalytic degradation activity toward OPPs, making them eco-friendly for self-cleaning regeneration and reducing laboratory pesticide discharge. This work highlights the potential of OMMIPs for high-throughput and in situ pesticide monitoring in modern large-scale agricultural markets.
