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.

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

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.

Heavy metal toxicity hinders plant growth and development by inducing oxidative stress, decreasing biomass, impairing photosynthesis, potentially leading to death. The inherent defense mechanisms employed plants, including sequestration into vacuoles, phytochelation, cell wall adsorption an enhanced antioxidant system can be improved via various approaches mitigate heavy toxicity. This review primarily outlines plants direct indirect responses HM stress the tolerance which combat toxic effects of metals metalloids understand effective management HMs in soil system. Furthermore, this highlights measures metalloid improve through physio-biochemical, biological, molecular approaches. also provides a comprehensive account all mitigative comparing biological Finally, we compared used monocotyledonous dicotyledonous increase their tolerance. Although many studies have monocot dicot based on effects, comparisons these not been explored.
