Microplastic stress in plants: effects on plant growth and their remediations

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: Aug. 11, 2023

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

Micro/nanoplastics pollution poses a potential threat to soil health

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(8)

Published: Aug. 1, 2024

Abstract Micro/nanoplastic (MNP) pollution in soil ecosystems has become a growing environmental concern globally. However, the comprehensive impacts of MNPs on health have not yet been explored. We conducted hierarchical meta‐analysis over 5000 observations from 228 articles to assess broad parameters (represented by 20 indicators relevant crop growth, animal health, greenhouse gas emissions, microbial diversity, and pollutant transfer) whether depended MNP properties. found that exposure significantly inhibited biomass germination, reduced earthworm growth survival rate. Under exposure, emissions gases (CO 2 , N O, CH 4 ) were increased. caused decrease bacteria diversity. Importantly, magnitude impact soil‐based was dependent dose size; however, there is no significant difference type (biodegradable conventional MNPs). Moreover, As uptake plants, but promoted plant Cd accumulation. Using an analytical hierarchy process, we quantified negative as mean value −10.2% (−17.5% −2.57%). Overall, this analysis provides new insights for assessing potential risks ecosystem functions.

Unveiling the mechanism of micro-and-nano plastic phytotoxicity on terrestrial plants: A comprehensive review of omics approaches

Environment International, Journal Year: 2025, Volume and Issue: 195, P. 109257 - 109257

Published: Jan. 1, 2025

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.

Abstract In the realm of global economy, agriculture holds a prominent status, acting as vital source employment and revenue for nations. Despite its crucial role, agricultural sector contends with recurrent annual losses attributable to market fluctuations. One noteworthy contributor decline in productivity is adverse impact microplastics (MPs). This study aims estimate production suffered by key crops—rice, wheat, maize, tomato, peas—due MPs, along resulting economic consequences arising from direct damage inflicted MPs. To assess caused secondary data diverse sources were employed five plant varieties. The MPs calculated period spanning 2017–2023, cumulative aggregated all states. study's findings indicate that presence corresponds an output ranging 0.4% 34.7%. translates reduction approximately 0.01 million 66.97 tons per year food, fiber, biofuels. aggregate yearly are estimated at around USD 46.5 billion. These carry substantial implications governmental policy domain, underscoring necessity current statistics on incurred due Moreover, they emphasize importance implementing systematic surveillance system monitor such effectively.

Leaf rolling (LR) is one of the defensive mechanisms that plants have developed against adverse environmental conditions. LR a typical drought response, promoting resistance in various gramineae species, including wheat, maize, and rice. Rice cultivation faces formidable challenge water deprivation because its high requirements, which leads to drought-related symptoms an important morphological characteristic plays key role controlling loss during insufficiency, thereby regulating leaf area stature, are crucial agronomic traits determining yield criteria. Bulliform, sclerenchyma, mesophyll, vascular bundles cells engage commonly exhibit adaxial or abaxial types The specific genes linked rolling, either adaxially abaxially, discussed here. In addition factors influencing LR, here short review morphological, physiological molecular responses this adaptation under stress.
