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.

Nanoplastics in the soil environment: Analytical methods, occurrence, fate and ecological implications

Environmental Pollution, Journal Year: 2022, Volume and Issue: 317, P. 120788 - 120788

Soils play a very important role in ecosystems sustainability, either natural or agricultural ones, serving as an essential support for living organisms of different kinds. However, the current context extremely high plastic pollution, soils are highly threatened. Plastics can change chemical and physical properties may also affect biota. Of particular importance is fact that plastics be fragmented into microplastics and, to final extent nanoplastics. Due their low size surface area, nanoplastics even have higher impact soil ecosystems. Their transport through edaphic environment regulated by physicochemical particles themselves, anthropic activities biota interactions. degradation associated with series mechanical, photo-, thermo-, bio-mediated transformations eventually conducive mineralisation. tiny precisely main setback when it comes sampling subsequent processes identification quantification, albeit pyrolysis coupled gas chromatography-mass spectrometry other spectroscopic techniques proven useful analysis. Another issue consequence minuscule lies uptake plants roots ingestion dwelling fauna, producing morphological deformations, damage organs physiological malfunctions, well risks entrance food chain, although conclusions not always consistent show same pattern effects. Thus, given omnipresence seriousness menace, this review article pretends provide general overview most recent data available regarding determination, occurrence, fate effects soils, special emphasis on ecological implications.

Brassinosteroids alleviate nanoplastic toxicity in edible plants by activating antioxidant defense systems and suppressing nanoplastic uptake

Environment International, Journal Year: 2023, Volume and Issue: 174, P. 107901 - 107901

Published: March 25, 2023

As emerging pollutants of global concern, absorbed nanoplastics might have negative impacts on plant development and nutrient uptake, thereby decreasing yields. If are transferred to the edible parts plants, they may pose a threat human health when large quantities ingested. While nanoplastic-induced phytotoxicity is attracting increasing attention, little known about how inhibit nanoplastic accumulation in plants reduce subsequent adverse effects. Here we investigated absorption polystyrene (PS-NPs) different species role brassinosteroids alleviating PS-NP toxicity. Brassinosteroids inhibited PS-NPs tomato fruit reversed PS-NP-induced promote growth increase fresh weight height. also induction aquaporin-related genes by including TIP2-1, TIP2-2, PIP2-6, PIP2-8, PIP2-9, SIP2-1, NIP1-2, providing potential stress mechanism which accumulate targets for inhibition. In transcriptomic analyses, enhanced fatty acid amino metabolism synthesis. conclusion, exogenous application 50 nM alleviated effects be an effective means minimize phytotoxicity.

Interaction of Microbes with Microplastics and Nanoplastics in the Agroecosystems—Impact on Antimicrobial Resistance

Pathogens, Journal Year: 2023, Volume and Issue: 12(7), P. 888 - 888

Published: June 29, 2023

Microplastics (MPs) and nanoplastics (NPs) are hotspots for the exchange of antimicrobial resistance genes (ARGs) between different bacterial taxa in environment. Propagation (AMR) is a global public health issue that needs special attention concerning horizontal gene transfer (HGT) under micro-nano plastics (MNPs) pressure. Interactions MNPs microbes, or mere persistence environment (either water soil), influence microbial expressions, affecting autochthonous microbiomes, their resistomes, overall ecosystem. The adsorption range co-contaminants on leads to increased interaction pollutants with microbes resulting changes AMR, virulence, toxin production, etc. However, accurately estimating extent MNP infestation agroecosystems remains challenging. main limitation level contamination agroecosystems, surface subsurface waters, sediments lack standardized protocols extraction MPs analytical detection methods from complex high organic content matrices. Nonetheless, recent advances matrices matter highly promising. This review aims provide an overview relevant information available date summarize already existing knowledge about mechanisms MNP-microbe interactions including factors HGT AMR. In-depth enhanced ARGs propagation could raise needed awareness, future consequences emergence multidrug-resistant bacteria.
