The emergence of polyvinyl chloride (PVC) microplastics (MPs) as pollutants in agricultural soils is increasingly alarming, presenting significant toxic threats to soil ecosystems. Ajwain (Trachyspermum ammi L.), a plant medicinal and culinary value, subjected environmental stressors that threaten its growth productivity. This situation particularly acute given the well-documented toxicity chromium (Cr), which has been shown adversely affect biomass escalate risks productivity such economically therapeutically important species. present study was conducted investigate individual effects different levels PVC−MPs (0, 2, 4 mg L−1) Cr 150, 300 kg−1) on various aspects growth. Specifically, we examined biomass, photosynthetic pigments, gas exchange attributes, oxidative stress responses, antioxidant compound activity (both enzymatic nonenzymatic), gene expression, sugar content, nutritional status, organic acid exudation, accumulation parts L.) seedlings, were also exposed varying titanium dioxide (TiO2) nanoparticles (NPs) 25, 50 µg mL−1). Results from showed increasing significantly decreased sugars, contents roots shoots plants. Conversely, increased indicators term malondialdehyde, hydrogen peroxide, electrolyte leakage, exudation pattern T. seedlings. Interestingly, application TiO2−NPs counteracted leading greater biomass. protective effect facilitated by NPs' ability sequester reactive oxygen species, thereby reducing lowering concentrations both Our research findings indicated enhance resilience seedlings toxicity, not only improved but healthier physiological state demonstrated more balanced acids, critical response mechanism metal stress.

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

BMC Plant Biology, Год журнала: 2024, Номер 24(1)

Опубликована: Окт. 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.

Nanotechnology has garnered significant interest worldwide due to its wide-ranging applications across various industries. Titanium dioxide nanoparticles are one type of nanoparticle that is commonly utilised in everyday use and can be synthesized by different techniques using physical, chemical biological extracts. Green synthesis an economical, environmentally benign non-toxic method synthesising nanoparticles. have a positive impact on plant physiology, particularly response biotic abiotic stresses, depending factors like size, concentration, exposure the other variables. Further, titanium many applications, such as being used nano-fertilizers, adsorption heavy metal from industrial wastewater antimicrobial activity, discussed this review paper. Previous studies investigated whether also induce genotoxicity may mishandling procedure, time, concentration This still contradictory requires more research. The present pragmatic approach summarize synthesis, application, nanotoxicity, eco-friendly disposable.

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.
