Abstract Background and aims Urban ornamental shrubs have significant potential for restoring cadmium (Cd)-contaminated soil. Simulated pot pollution was applied to Buxus sinica and Ligustrum × vicaryi to study their Cd enrichment characteristics tolerance mechanisms. Methods content accumulation were analyzed in different plant organs, subcellular distribution chemical forms of the roots, effects on ultrastructure root cells under various concentrations (0, 25, 50, 100, 200 mg·kg⁻¹). Results (1) With increasing treatment levels, total biomass B. sinica gradually decreased, while L. ×vicaryi exhibited a stimulation effect at low inhibition high concentrations. (2) The organs both increased with rising L. × vicaryi showing significantly higher increase than sinica, indicating stronger capability vicaryi. (3) primarily present NaCl-extractable forms, majorly bound cell wall. (4) Excessive caused damage cellular structure leaves, while L. × vicaryileaves maintained normal morphology. (5) In shrubs, binds wall through hydroxyl, amino functional groups, soluble sugars. Conclusion Converting less active immobilizing wall, providing binding sites groups may be crucial resistance mechanisms response stress.

Cadmium (Cd) exerts a toxic influence on numerous crucial growth and development processes in plants, notably affecting seed germination rate, transpiration chlorophyll content, biomass. While considerable advances Cd uptake detoxification of plants have been made, the mechanisms by which adapt to tolerate toxicity remain elusive. This review focuses relationship between prospects for phytoremediation pollution. We highlight following issues: (1) present state pollution its associated hazards, encompassing sources distribution risks posed human health; (2) underlying transport Cd, including physiological with uptake, translocation, as well pertinent gene families implicated these processes; (3) detrimental effects detoxification, such activation resistance genes, root chelation, vacuolar compartmentalization, antioxidant systems generation non-enzymatic antioxidants; (4) practical application impact incorporating exogenous substances tolerance plants.

Cadmium (Cd), as the most prevalent heavy metal contaminant poses serious risks to plants, humans, and environment. The ubiquity of this toxic is continuously increasing due rapid discharge industrial mining effluents excessive use chemical fertilizers. Nanoparticles (NPs) have emerged a novel strategy alleviate Cd toxicity. Zinc oxide nanoparticles (ZnO-NPs) become important NPs used mitigate toxicity abiotic stresses improve crop productivity. plants quickly absorb Cd, which subsequently disrupts plant physiological biochemical processes increases production reactive oxygen species (ROS), causes oxidation cellular structures significant growth losses. Besides this, also leaf osmotic pressure, nutrient uptake, membrane stability, chlorophyll synthesis, enzyme activities, leading reduction in biomass Though possess an excellent defense mechanism counteract toxicity, not enough counter higher concentrations Applying Zn-NPs has proven potential mitigating effects Cd. ZnO-NPs photosynthetic efficiency, gene expression, can help stress. Additionally, reduce absorption accumulation complex relationship between ZnO-NPs, osmolytes, hormones, secondary metabolites plays role tolerance. Thus, review concentrates on exploring diverse mechanisms by ZnO plants. In end, identified various research gaps that need addressing ensure promising future findings contribute gaining deeper understanding combating promote safer sustainable remediating Cd-polluted soils. This allows for development eco-friendly approaches remediate soils soil fertility environmental quality.

In this work, we demonstrated, for first time, nature and scale alterations at tissue cellular levels occurring Norway maple growing on sludge originating from copper mine Lubin (Poland). The differs other wastes, calamine or serpentine soils, due to extremely high arsenic (As). anatomy predominantly included following: (1) significant increase upper epidermis thickness; (2) decrease palisade parenchyma width; (3) more compact organization; (4) occurrence two three cell layers contrast one control; (5) significantly smaller size cells building parenchyma. At level, mainly local wall thickenings—predominantly lower epidermis—and symptoms accelerated senescence. Nevertheless, many chloroplasts showed almost intact chloroplast ultrastructure. Modifications could symptom morphogenesis but may also related adaptation water deficit stress. thickenings considered defence strategy involved enlargement apoplast volume toxic elements (TE) sequestration alleviation oxidative Importantly, ultrastructure was not markedly disturbed. results suggested that have good potential. However, general shape plant, leaves, senescence indicated experiment. Hence, such substrate, specifically including use maple, should preceded by some amendments—which are highly recommended.
