Micro-and-nano plastics (MNPs) are pervasive in terrestrial ecosystems and represent an increasing threat to plant health; however, the mechanisms underlying their phytotoxicity remain inadequately understood. MNPs can infiltrate plants through roots or leaves, causing a range of toxic effects, including inhibiting water nutrient uptake, reducing seed germination rates, impeding photosynthesis, resulting oxidative damage within system. The effects complex influenced by various factors size, shape, functional groups, concentration. Recent advancements omics technologies such as proteomics, metabolomics, transcriptomics, microbiomics, coupled with emerging like 4D omics, phenomics, spatial single-cell offer unprecedented insight into physiological, molecular, cellular responses exposure. This literature review synthesizes current findings regarding MNPs-induced phytotoxicity, emphasizing alterations gene expression, protein synthesis, metabolic pathways, physiological disruptions revealed analyses. We summarize how interact structures, disrupt processes, induce stress, ultimately affecting growth productivity. Furthermore, we have identified critical knowledge gaps proposed future research directions, highlighting necessity for integrative studies elucidate pathways toxicity plants. In conclusion, this underscores potential approaches MNPs-phytotoxicity develop strategies mitigating environmental impact on health.

The widespread application of biodegradable microplastics (MPs) in recent years has resulted a significant increase their accumulation the environment, posing potential threats to ecosystems. Thus, it is imperative evaluate distribution and transformation MPs crops due utilization wastewater containing for irrigation plastic films, which have led rising concentration agricultural soils. present study analyzed uptake polylactic acid (PLA) maize. Seed germination hydroponic experiments were conducted over period 5 20 days, during plants exposed PLA at concentrations 0, 1, 10, 100 mg L-1. Low (1 L-1 10 L-1) significantly enhanced maize seed rate by 52.6%, increased plant shoot height 16.6% 16.9%, respectively, as well elevated aboveground biomass dry weight 133.7% 53.3%, respectively. Importantly, depolymerization was observed nutrient solution, resulting formation small-sized (< 2 μm). Interestingly, further occurred within xylem sap apoplast fluid (after 12 h) with reaching 13.1% 27.2%, growth could be attributed dissolved organic carbon from MPs. Additionally, mediated pH K+ flux (57.2%, 72 h), leading acidification cell wall subsequent expansion. Our findings provide evidence regarding fate interactions plants, thereby enhancing our understanding impacts associated plastics.
