Plastics have inundated the world, with microplastics (MPs) being small particles, less than 5 mm in size, originating from various sources. They pervade ecosystems such as freshwater and marine environments, soils, and the atmosphere. MPs, due to their small size and strong adsorption capacity, pose a threat to plants by inhibiting seed germination, root elongation, and nutrient absorption. The accumulation of MPs induces oxidative stress, cytotoxicity, and genotoxicity in plants, which also impacts plant development, mineral nutrition, photosynthesis, toxic accumulation, and metabolite production in plant tissues. Furthermore, roots can absorb nanoplastics (NPs), which are then distributed to stems, leaves, and fruits. As MPs and NPs harm organisms and ecosystems, they raise concerns about physical damage and toxic effects on animals, and the potential impact on human health via food webs. Understanding the environmental fate and effects of MPs is essential, along with strategies to reduce their release and mitigate consequences. However, a full understanding of the effects of different plastics, whether traditional or biodegradable, on plant development is yet to be achieved. This review offers an up-to-date overview of the latest known effects of plastics on plants.

“…Nano-polystyrene modified with amino groups has positive charges on the surface, which will generate electrostatic attraction with negatively charged polysaccharides secreted by plant roots, which will be more absorbed by plants; 41 nano-polystyrene whose surface is modi-fied with carboxyl functional groups will generate electrostatic repulsion with plant roots, and the accumulation in plants is less. 42 Fig. 1a-e show the images of Pistia stratiotes' roots in the experimental group and control group captured using a laser confocal microscope at different magnifications.…”

“…The surface charge groups of MPs also determine the negative effects of MPs on root growth, for instance, functional groups such as -NH 2 and -SO 3 H reduced root and shoot biomass and root volume ( Xu et al., 2022 ). The -NH 2 functional group contains a positive charge, which can easily occupy the binding sites and be easily adsorbed by the cell wall, thereby hindering the adsorption of cationic elements such as K + Ca 2+ or H + , Pb 2+ around roots ( Li et al., 2020 ; Song et al., 2023 ). Contrarily, -SO 3 H is of strong hydrophilic nature and contains a negative charge, and can closely combine with the hydrophobic functional group of the phospholipids in the cell membrane, thus it can easily enter the cells to cause cytotoxic effects in roots ( Feng et al., 2019 ).…”

Microplastic (MP) pollution is becoming a global problem due to the resilience, long-term persistence, and robustness of MPs in different ecosystems. In terrestrial ecosystems, plants are exposed to MP stress, thereby affecting overall plant growth and development. This review article has critically analyzed the effects of MP stress in plants. We found that MP stress-induced reduction in plant physical growth is accompanied by two complementary effects: (i) blockage of pores in seed coat or roots to alter water and nutrient uptake, and (ii) induction of drought due to increased soil cracking effects of MPs. Nonetheless, the reduction in physiological growth under MP stress is accompanied by four complementary effects: (i) excessive production of ROS, (ii) alteration in leaf and root ionome, (iii) impaired hormonal regulation, and (iv) decline in chlorophyll and photosynthesis. Considering that, we suggested that targeting the redox regulatory mechanisms could be beneficial in improving tolerance to MPs in plants; however, antioxidant activities are highly dependent on plant species, plant tissue, MP type, and MP dose. MP stress also indirectly reduces plant growth by altering soil productivity. However, MP-induced negative effects vary due to the presence of different surface functional groups and particle sizes. In the end, we suggested the utilization of agronomic approaches, including the application of growth regulators, biochar, and replacing plastic mulch with crop residues, crop diversification, and biological degradation, to ameliorate the effects of MP stress in plants. The efficiency of these methods is also MP-type-specific and dose-dependent.
