摘要:

近年来,塑料制品使用的持续增长导致微塑料污染问题日益严重。微塑料因其难降解性、小粒径、广泛分布且易被生物摄取等特性,对自然环境构成严重威胁。其中,微塑料对陆地生态系统,特别是农业生态系统的污染风险正受到广泛关注。高等植物作为生态系统中不可或缺的一环,在维持生态平衡中扮演着关键角色。本研究综述了微塑料的定义、来源及其进入植物途径,系统阐述了微塑料对高等植物生长和发育的具体影响,探讨了植物应对微塑料胁迫的生理响应及其对植物激素的调控作用,例如,微塑料进入植物可能导致控制有丝分裂关键基因CDC2的表达下调,扰乱植物生长周期;同时,影响GDT1、GDH2、GAD等参与植物三羧酸循环的关键基因的表达,并降低腺嘌呤核苷三磷酸(ATP)的合成速率,进而影响光合作用。这些基因表达下调,最终损害植物必需的营养代谢过程。此外,本文还分析了微塑料影响植物激素的作用机制和植物抗氧化系统的响应。这些研究有助于深入理解微塑料对植物生物学的复杂效应。在此基础上,展望了未来的研究方向,并评估了微塑料污染的潜在生态风险。通过整合当前对微塑料影响植物生物学的认知,本研究旨在为微塑料污染的防控和管理提供科学依据,促进生态系统的可持续发展。总之,本综述不仅总结了当前关于微塑料影响高等植物生长发育的研究,还提出了新的研究思路,为应对微塑料污染挑战提供了重要参考。

Abstract:

In recent years, the continuous growth in the use of plastic products has led to an increasingly prominent problem of microplastic pollution. Due to their non-biodegradability, small particle size, wide distribution, and easy uptake by organisms, microplastics pose a serious threat to the natural environment. Among them, the pollution risk of microplastics to terrestrial ecosystems, especially agricultural ecosystems, is receiving increasing attention. Higher plants, as an indispensable part of the ecosystem, play a key role in maintaining ecological balance. This review summarizes the definition, sources, and entry pathways of microplastics into plants, comprehensively discusses on the specific impacts of microplastics on the growth and development of higher plants, and explores the physiological responses of plants to microplastic stress and their regulatory effects on plant hormones. For example, the entry of microplastics into plants may lead to the down-regulation of the expression of the key gene CDC2 that controls mitosis, disrupting the plant growth cycle; at the same time, it affects the expression of key genes such as GDT1, GDH2 and GAD involved in the plant tricarboxylic acid cycle, and reduces the rate of adenosine triphosphate (ATP) synthesis, thereby affecting photosynthesis. The down-regulation of these gene expressions ultimately damages the essential nutrient metabolism processes of plants. In addition, this article also analyzes the mechanism by which microplastics affect plant hormones and the responses of the plant antioxidant system. These studies contribute to a deeper understanding of the complex effects of microplastics on plant biology. On this basis, future research directions are prospected, and the potential ecological risks of microplastic pollution are evaluated. By integrating the current understanding of the impact of microplastics on plant biology, this study aims to provide a scientific basis for the prevention, control and management of microplastic pollution, and contribute to the sustainable development of ecosystems. In summary, this review not only summarizes the current research on the effects of microplastics on the growth and development of higher plants but also proposes new research ideas, providing an important reference for addressing the challenges of microplastic pollution.
