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.

Biochar-mediated remediation of uranium-contaminated soils: evidence, mechanisms, and perspectives

Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Published: March 1, 2024

Abstract Soil contamination by uranium presents a burgeoning global environmental concern, exerting detrimental effects on both agricultural production and soil health. Biochar, carbonaceous material derived from biomass pyrolysis, exhibits considerable potential for remediating uranium-contaminated soils. However, comprehensive review of the biochar fate accumulation in soil–plant systems remains conspicuously absent. In this paper, sources are reviewed, impact immobilization detoxification is analyzed. We reviewed status soils globally found that mining activities currently main sources. Further meta-analysis revealed addition significantly reduced bioavailability shoot accumulation, their effect value 58.9% (40.8–76.8%) 39.7% (15.7–63.8%), respectively. Additionally, enhances microenvironment, providing favourable conditions promoting plant growth reducing mobility. focused mechanisms governing interaction between uranium, emphasising roles played surface complexation, reduction, ion exchange, physical adsorption. The modification intensifying these can promote immobilisation Finally, alleviates oxidative stress reduces tissues, thereby mitigating adverse development. Overall, our highlights capacity to remediate through diverse mechanisms, valuable insights sustainable remediation. Highlights Biochar mobility variety including limits its plants. Modified has been shown enhance effectiveness immobilising uranium. application not only promotes remediation but also improves quality. Graphical

Engineered biochar improves nitrogen use efficiency via stabilizing soil water-stable macroaggregates and enhancing nitrogen transformation

Biochar, Journal Year: 2023, Volume and Issue: 5(1)

Published: Sept. 1, 2023

Abstract The use of inorganic nitrogen (N) fertilizers has increased drastically to meet the food requirements world's growing population. However, excessive chemical fertilizer caused a series soil and environmental problems, such as hardening, lower efficiency (NUE), nitrate pollution water sources, nitrous oxide emissions, etc. In this review, we aimed elaborate discuss role engineered biochar in inducing stability water-stable macroaggregates, improving N transformation, utilization address current uncertainties loss maintaining quality. Firstly, elucidated characteristics quality work multifunctional player ecosystem promote resource utilization, conservation, preservation. Secondly, discussed how modulates macroaggregates transformation enhance plant response under various toxic or deficient conditions soil. Thirdly, biological fixation, mediating nirK , nirS nosZ genes conversion 2 O decreasing denitrification emission was reviewed. Altogether, suggest that amendment can regulate reduce input, improve metabolism, finally, NUE crop growth.

Seed Priming with Zinc Oxide Nanoparticles to Enhance Crop Tolerance to Environmental Stresses

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(24), P. 17612 - 17612

Published: Dec. 18, 2023

Drastic climate changes over the years have triggered environmental challenges for wild plants and crops due to fluctuating weather patterns worldwide. This has caused different types of stressors, responsible a decrease in plant life biological productivity, with consequent food shortages, especially areas under threat desertification. Nanotechnology-based approaches great potential mitigating thus fostering sustainable agriculture. Zinc oxide nanoparticles (ZnO NPs) demonstrated be biostimulants as well remedies both biotic stresses. Their administration early sowing stages, i.e., seed priming, proved effective improving germination rate, seedling growth ameliorating indicators plants' well-being. Seed nano-priming acts through several mechanisms such enhanced nutrients uptake, improved antioxidant properties, ROS accumulation lipid peroxidation. The target priming by ZnO NPs is mostly large consumption or staple food, order meet increased needs growing population net drop global crop frequency, soil contaminations. current review focuses on most recent low-cost, low-sized employed nano-priming, alleviate abiotic stresses, mitigate negative effects improper storage biostimulate Taking into account that there variability among their chemico-physical properties may play role determining efficacy all examined cases, it reported whether are commercial lab prepared.
