In recent years, plastic pollution has become a global environmental problem, posing a potential threat to agricultural ecosystems and human health, and may further exacerbate global food security problems. Studies have revealed that exposure to micro/nano-plastics (MPs/NPs) might cause various aspects of physiological toxicities, including plant biomass reduction, intracellular oxidative stress burst, photosynthesis inhibition, water and nutrient absorption reduction, cellular and genotoxicity, seed germination retardation, and that the effects were closely related to MP/NP properties (type, particle size, functional groups), exposure concentration, exposure duration and plant characteristics (species, tissue, growth stage). Based on a brief review of the physiological toxicity of MPs/NPs to plant growth, this paper comprehensively reviews the potential molecular mechanism of MPs/NPs on plant growth from perspectives of multi-omics, including transcriptome, metabolome, proteome and microbiome, thus to reveal the role of MPs/NPs in plant transcriptional regulation, metabolic pathway reprogramming, protein translational and post-translational modification, as well as rhizosphere microbial remodeling at multiple levels. Meanwhile, this paper also provides prospects for future research, and clarifies the future research directions and the technologies adopted.
近年来，塑料污染已成为全球性的环境问题，对农业生态系统和人类健康构成潜在威胁，可能进一步加剧全球粮食安全问题。研究表明，暴露于微/纳米塑料（MPs/NPs）可能会导致植物产生各种生理毒性，包括生物量减少、细胞内氧化应激爆发、光合作用抑制、水和养分吸收减少、细胞和遗传毒性、种子发芽延迟等，这些影响与 MPs/NPs 的特性（类型、粒径、官能团）、暴露浓度、暴露时间以及植物特性（物种、组织、生长阶段）密切相关。本文在简要综述 MPs/NPs 对植物生长的生理毒性的基础上，从多组学的角度，包括转录组学、代谢组学、蛋白质组学和微生物组学，综合评述了 MPs/NPs 对植物生长的潜在分子机制，从而揭示 MPs/NPs 在植物转录调控、代谢途径重编程、蛋白质翻译和翻译后修饰以及根际微生物重塑等多个层面的作用。同时，本文还对未来的研究提供了展望，并阐明了未来的研究方向和采用的技术。
