Ameliorating arsenic and PVC microplastic stress in barley (Hordeum vulgare L.) using copper oxide nanoparticles: an environmental bioremediation approach

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: Oct. 19, 2024

The present study investigates the impact of varying concentrations PVC microplastics (PVC–MPs) – specifically 0 (no PVC–MPs), 2, and 4 mg L− 1 –alongside different arsenic (As) levels As), 150, 300 kg− in soil, with concurrent application copper oxide–nanoparticles (CuO–NPs) at CuO –NPs), 25 50 µg mL− to barley (Hordeum vulgare L.) plants. This research primarily aims assess plant growth biomass, photosynthetic pigments gas exchange characteristics, oxidative stress indicators, as well response various antioxidants (both enzymatic non-enzymatic) their relevant genes expression, proline metabolism, AsA–GSH cycle, cellular fractionation within findings showed that increased PVC–MPs As soil significantly reduced pigments, characteristics. Additionally, roots shoots, evidenced by elevated malondialdehyde (MDA), hydrogen peroxide (H2O2), electrolyte leakage (EL), which turn stimulated production non-enzymatic antioxidants, gene sugar content. Furthermore, a notable increase pigmentation was observed. Conversely, CuO–NPs resulted substantial improvement activity along reduction stress. enhanced while decreasing metabolism AsA-GSH cycle H. These outcomes provide new insights into sustainable agricultural practices offer significant potential addressing critical challenges heavy metal contamination soils.

Role of syringic acid in enhancing growth, photosynthesis, and antioxidant defense in lettuce exposed to arsenic stress

Physiologia Plantarum, Journal Year: 2025, Volume and Issue: 177(1)

Published: Jan. 1, 2025

Heavy metal pollution, especially arsenic toxicity, significantly impairs plant growth and development. Phenolic acids, known for their antioxidant properties involvement in stress signaling, are gaining increased attention as secondary metabolites with the potential to enhance resistance these stressors. This study aimed investigate effects of different concentrations syringic acid (SA1, 10 μM; SA2, 250 SA3, 500 μM) on growth, photosynthetic parameters, activity lettuce seedlings subjected (As, 100 μM). Arsenic reduced by 56.7%, water content 7.39%, osmotic 26.2% leaves compared control. Conversely, SA1 SA2 treatments mitigated adverse preserved balance plants. However, SA3 treatment led a decrease 18.9% 39.5% As+SA3 groups, respectively, indicating that high-dose SA adversely affected under both control conditions. Exogenous improved photosynthesis, whereas provided milder benefits did not reduce exposure. H2O2 47.3% lipid peroxidation 33.4% seedlings. effectively oxidative enhancing activities key enzymes, such superoxide dismutase (SOD) peroxidase (POX). Moreover, was successful maintaining glutathione (GSH) pool, primarily promoted ascorbate (AsA) regeneration. In conclusion, μM (SA1) identified optimal dose reducing supporting growth. Overall, findings underscore resilience heavy toxicity.

Priming agents combat copper stress in wheat (Triticum aestivum L.) under hydroponic conditions: Insights in impacts on morpho–physio–biochemical traits and health risk assessment

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 291, P. 117899 - 117899

Published: Feb. 1, 2025

In recent years, the use of priming agents, such as silicon, melatonin, salicylic acid, glycine betaine, and ascorbic acid has gained significant attention for their role in mitigating abiotic stresses across various plant species. While previous research been conducted on individual impact metal stress resistance among crop species, combined effects context heavy stressed conditions remain underexplored. Wheat (Triticum aestivum L.) seedlings was grown under toxic concentration copper (Cu) i.e., 100 µM which were applied with hydroponic 21 days. The outcomes indicated that Cu nutrient solution notably reduced growth biomass, photosynthetic pigments, gas exchange attributes. However, also induced oxidative plants by increasing malondialdehyde (MDA), hydrogen peroxide (H2O2) increased compounds enzymatic non-enzymatic antioxidants, health risk index (HRI) gene expression sugar content. Furthermore, a increase proline metabolism, AsA-GSH cycle, pigmentation cellular components observed. Although, application different showed characteristics, compounds, decreased HRI. addition, agents enhanced fractionation metabolism cycle T. seedlings. These results open new insights sustainable agriculture practices hold immense promise addressing pressing challenges contamination agricultural soils.
