“…MPs pose a unique challenge owing to their resistance to degradation, their potential absorption by plant roots, and their subsequent transport to aboveground parts. Remediation approaches may involve immobilizing or extracting MPs from soils to aboveground plant structures (Li et al, 2023). Although root immobilization may not eliminate all MPs, it can limit their mobility and accessibility and thus reduce their over ecological impacts and risks.…”

“…Additionally, the adsorption of MPs by plants may influence plant metabolism through enzymatic actions, potentially leading to the transformation of MPs into plant biomass or inorganic products, such as CO 2 and CH 4 . A comprehensive understanding of these processes, particularly their impacts on different C pools within ecosystems, is crucial for future research on MP phytoremediation systems(Li et al, 2023). Incorporating biodegradable plastics, which are considered safe and easily degraded by microbes, along with responsible waste management, presents potential solutions for MP and NP pollution.…”

Microplastic (MP) pollution is an important environmental problem owing to its widespread use, long residence time, and overall persistence. MPs threaten the health of humans, animals, and plants. However, studies on the effects of MPs on terrestrial plants are less common compared to those conducted in aquatic systems. This review discusses the sources of MPs in terrestrial ecosystems, their effects on C and N cycling in soils, and the impact of MPs on terrestrial plants, and focuses on plant growth and the potential risks to human health. MPs affect plants and their performance by altering soil structure, microbial activity, nutrient immobilization, transporting contaminants, and causing direct toxicity. Chemicals, such as plasticizers, additives, and colorants, in MPs may negatively affect ecosystems and their inhabitants, and MPs may interact with a wide array of pollutants, including pesticides, heavy metals, and antibiotics. These impacts vary as a function of soil type, plant species, and MP type. Future research efforts should focus on interaction complexity, uptake mechanisms, and impacts on plants at multiple spatiotemporal scales, while concurrently considering their effects on food chains and human health.

“…Uma vez absorvidos pelas células, os metais tóxicos são transcolados a curta e a longa distância sendo acumulados em diferentes órgãos das plantas, especialmente na parte aérea (folhas e frutos) (LI et al, 2023). Em frutos, por exemplo, o acúmulo dos metais tóxicos pode trazer riscos à saúde humana tendo em vista a sua ingestão, além disso ao serem inseridos no ambiente estes metais passam a participar da cadeia trófica de modo a causar prejuízos a longo prazo (KAPOOR et al, 2021;FAN et al, 2023), conforme efeitos apresentados na Tabela 1.…”

“…Indeed, researchers have reported that priming wheat seeds with zinc ions or zinc oxide nanoparticles can effectively decrease the accumulation of Cd in grains grown in Cd-contaminated alkaline fields. , However, the molecular and metabolic mechanisms associated with seed priming remain poorly understood . Generally, the absorption of Cd by roots is facilitated through the transporters or channels that have evolved to absorb essential metals such as copper (Cu), iron (Fe), zinc (Zn), and manganese (Mn) . Previous work reported that by utilizing essential nutrients, like Zn and Mn, the buildup of Cd in plants can be reduced because of the competition between Cd and these nutrients for the same membrane transporters. − Moreover, seed priming can induce stress and immune responses by increasing the production of signal- and defense-related metabolites and genes, resulting in a prompt and robust defense mechanism against potential stresses .…”

Seed soaking is a viable solution for reducing cadmium (Cd) levels in wheat, given the limited options for economically controlling it. This study aimed to explore the precise mechanisms behind seed priming to reduce Cd levels in wheat seedlings via plant ionomics, transcriptomics, and high-throughput sequencing technologies. The results showed that seed soaking with Mn 2+ (100 μM) significantly improved the growth parameters of wheat seedlings. Seed priming with Ag + (1, 2 μM) significantly decreased Cd levels in the roots (32.9 and 40.6%, respectively) and stems (19.4 and 20.3%, respectively), whereas seed priming with Zn 2+ (10 mM) and Mn 2+ (20, 100 μM) significantly decreased Cd levels in the leaves (29.4, 15.6, and 33.5%, respectively) compared to that in the control group. These varied reductions of Cd in wheat seedlings induced by seed soaking were attributed to the restructuring of gene transcription involved in Cd absorption and the recruitment of the genus Rhizopus (plant-beneficial fungi tolerant to Cd) in the rhizosphere soil. It shows that seed soaking could effectively control Cd absorption by wheat in a weakly alkaline soil.
