“…Lettuce (Lactuca sativa L.) is a major food source grown worldwide. Wang et al [ 61 ] observed the effects of PS plastic on lettuce growth and found that PS MPs can disturb the antioxidant system, change the gene expression in roots, and influence the root exudate profiles. MP stress increased the expression of genes involved in different antioxidant systems at different times in the roots and leaves (ascorbic acid, terpenoids, flavonoids, and sphingolipids).…”

“…MP stress increased the expression of genes involved in different antioxidant systems at different times in the roots and leaves (ascorbic acid, terpenoids, flavonoids, and sphingolipids). The solutions with higher MP concentrations further inhibited lettuce growth compared to the controls, and the fresh leaf weight, plant height, and number of leaves were significantly reduced in all of the plants grown in the presence of MPs ( p < 0.05) [ 61 ].…”

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.

“…MP stress negatively affects the growth of shoots and leaves ( Table 2 ) by reducing cell elongation during the developmental phase, affecting the supply of nutrients, causing physical damage to xylem vessels, and influencing shoot and leaf biomass production. Furthermore, PS MP stress reduced leaves’ fresh weight, number of leaves per plant, leaf surface area, SPAD value, and overall plant height in a dose-dependent manner ( Wang et al., 2023c ).

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.
