Clonal integration orchestrates a plant-microbe alliance for systemic resilience to copper-based nanopesticides

Xuchen Yan, Erkai He, Willie J.G.M. Peijnenburg, Zhiling Guo et autres

Engineered nanomaterials particularly copper oxide nanoparticles (CuO NPs) are being rapidly integrated into modern agriculture as highly efficient and multifunctional nanoagrochemicals to enhance crop management and sustainability. However, their ecological risk assessments remain fundamentally constrained by conventional single-plant toxicity assays, which critically …

Dietary Fat and Fiber Divergently Control Intestinal Nanoplastic Bioaccumulation through Gut Motility and Barrier Pathways

Zewen Ji, Erkai He, Zhiling Guo, Peng Zhang et autres

The ingestion of nanoplastics (NPs) poses a growing environmental health threat, yet how intrinsic host factors modulate their intestinal fate remains poorly defined. This study tests the hypothesis that dietary patterns govern NP bioaccumulation by differentially regulating gut motility and barrier integrity. …

Ecotype-Specific Drilosphere Microbiome Reprogramming Influencing Microplastic Impacts on Soil Carbon–Nitrogen Characteristics and Earthworm Health

L W Wang, Hao Qiu, Hongyan Ma, Qingqiu Xi et autres

The soil drilosphere is a critical biogeochemical hotspot, yet its role as a key interface for microplastic (MP) accumulation and impact remains poorly characterized. We investigated how polyethylene microplastics (<150 μm) affect the drilosphere compartments (gut, burrows, and casts) of two distinct …

Vaccinating radish with CeO2 nanoparticles: a nano-priming strategy to activate systemic defense against atmospheric cadmium

L W Wang, Hao Qiu, Cornelis A.M. Van Gestel, Qingqiu Xi et autres

• CeO 2 -NPs pre-priming alleviates atmospheric deposition Cd-induced phytotoxicity. • CeO 2 nanoparticles pre-priming reduces Cd uptake by 26.2–60.5% in plants. • Pre-priming effects were linked with early activation of ROS levels in whole plants • CeO 2 -NPs activated signaling …

Divergent molecular mechanisms underlie differential toxicity of trivalent lanthanum and divalent cadmium in Enchytraeus crypticus

Bing Gong, Erkai He, Hao Qiu

Co-contamination of soil by trivalent rare earth elements (REEs) and divalent non-essential metals has raised increasing ecological concerns. However, the differential toxic mechanisms of these two metal categories in soil invertebrates, particularly under combined exposure, remain poorly understood. Here, we investigated the …

Rewiring Micro-Food Webs: How Copper Nanopesticides Can Reshape Nitrogen Fluxes via Trophic Decoupling

Xuchen Yan, Jason C. White, Erkai He, Willie J.G.M. Peijnenburg et autres

The extensive application of copper-based nanopesticides (Cu-based NPs) in agroecosystems can pose significant ecological risks to soil nitrogen (N) cycling through microbial-mediated mechanisms, yet microfood web-driven regulatory feedbacks remain poorly understood. Through a microcosm experiment with CuO NPs and silica-encapsulated CuO@SiO 2 …

Irreversible Immune Dysfunction in Earthworms from MoS 2 Nanosheet Exposure: Implications for Nanoenabled Agricultural Sustainability

Kailun Sun, Jason C. White, Iseult Lynch, Peng Zhang et autres

Nano-MoS 2 is emerging as a promising agricultural nanomaterial. However, nanoenabled agriculture must balance the proposed benefits with potential risks associated with material incorporation into soil matrices. This work establishes a full-process risk assessment profile for MoS 2 encompassing precursor particles, exfoliated …

Species-Specific Foliar Absorption and Translocation of Nanoplastics in Leafy Vegetables Revealed through Isotopic, Physiological, and Transcriptomic Analyses

Xiaofeng Jiang, Hao Qiu, Xing Li, Wenbo Guo et autres

Understanding the foliar absorption and translocation of atmospherically deposited nanoplastics (NPs) in crops is critical for food safety, yet species-specific mechanisms remain inadequately understood, hindering accurate risk assessment for edible crops. In this study, the isotopic tracing ( 2 H-labeled polystyrene NPs) …
