The advent of the nanotechnology era offers a unique opportunity for sustainable agriculture provided that the exposure and toxicity are adequately assessed and properly controlled. The global production and application of cerium oxide nanoparticles (CeO₂-NPs) in various industrial sectors have tremendously increased. Most of the nanoparticles end up in water and soil where they interact with soil microorganisms and plants. Investigating the uptake, translocation and accumulation of CeO₂-NPs is critical for its safe application in agriculture. Plant uptake of CeO₂-NPs may lead to their accumulation in different plant tissues and interference with key metabolic processes of plants. Soil microbes can also be affected by increasing CeO₂-NPs in soil, leading to changes in the physiology and enzymatic activity of soil microorganisms. The interactions between CeO₂-NPs, microbes and plants in the agricultural system need systemic research in ecologically relevant conditions. In the present review, The uptake pathways and in-planta translocation of CeO₂-NPs,and their impact on plant morphology, nutritional values, antioxidant enzymes and molecular determinants are presented. The role of CeO₂-NPs in modifying soil microbial community in plant rhizosphere is also discussed. Overall, the review aims to provide a comprehensive account on the behaviour of CeO₂-NPs in soil-plant systems and their potential impacts on the soil microbial community and plant health.

纳米技术时代的到来为可持续农业提供了一个独特的机会，前提是对暴露和毒性进行了充分的评估和适当的控制。氧化铈纳米粒子（CeO ₂ -NPs）在各个工业领域的全球生产和应用已大大增加。大多数纳米粒子最终进入水和土壤，在那里它们与土壤微生物和植物相互作用。研究 CeO ₂ -NPs的吸收、易位和积累对其在农业中的安全应用至关重要。植物对CeO ₂ -NPs 的吸收可能导致它们在不同植物组织中的积累并干扰植物的关键代谢过程。增加 CeO ₂也会影响土壤微生物-土壤中的NPs，导致土壤微生物生理和酶活性的变化。农业系统中CeO ₂ -NPs、微生物和植物之间的相互作用需要在生态相关条件下进行系统研究。在本综述中，介绍了CeO ₂ -NPs的摄取途径和植物内易位，及其对植物形态、营养价值、抗氧化酶和分子决定因素的影响。还讨论了 CeO ₂ -NPs 在改变植物根际土壤微生物群落中的作用。总体而言，该审查旨在全面说明 CeO ₂的行为- 土壤-植物系统中的纳米颗粒及其对土壤微生物群落和植物健康的潜在影响。
