The contamination of soil and water with high levels heavy metals (HMs) has emerged as a significant obstacle to agricultural productivity overall crop quality. Certain HMs, although serving essential micronutrients, are required in smaller quantities for plant growth. However, when present higher concentrations, they become very toxic. Several studies have shown that balance out the harmful effects complex systems needed at molecular, physiological, biochemical, cellular, tissue, whole levels. This could lead more crops being grown. Our review focused on HMs' resources, occurrences, implications. will also look how plants react HMs affect seed performance well benefits provide plants. Furthermore, examines transport genes their metabolic responses HMs. We examined obstacles potential management strategies.

ABSTRACT Lead (Pb) and arsenic (As) pollution seriously affect the physiological biochemical processes of plants, reduce agricultural productivity, pose a serious threat to human health. Recently, there has been an increasing interest in studies aimed at mitigating these negative effects heavy metals. Curcumin is important secondary metabolite belonging polyphenol class that provides stress tolerance plants through its metal‐chelating activity. Therefore, our study, curcumin (Cur1; 50 μM Cur2; 100 μM) was applied lettuce ( Lactuca sativa L.) under lead (Pb; and/or (As; stress. It observed relative growth rate plant decreased by 12% Pb 27% As combined conditions (Pb + As) reduced water content 23%. Notably, significant increases parameters were following treatment. Furthermore, exogenous application effectively mitigated detrimental induced heavy‐metal On gas exchange photosynthetic parameters, Cur1 treatment resulted more than twofold increase carbon assimilation conditions. Due exposure, H 2 O increased 25% TBARS twofold. These elevations attenuated with enhanced antioxidant enzyme Compared Cur2 treatments 40% 24% SOD activity, respectively. contributed maintenance redox balance cell activity ascorbate–glutathione (AsA‐GSH) cycle. In conclusion, applications reduction ROS accumulation uptake, photosynthesis efficiency, capacity. findings suggest phenolic compounds like could be promising strategy practices enhance resistance stress, thereby improving productivity.

Background: Heavy metal contamination significantly threatens crop growth and global food security. Understanding plant responses to such stress is crucial developing stress-tolerant crops. This study explores the physiological biochemical of Vigna radiata (L.) R. Wilczek mercury, lead, copper stress, focusing on role soluble sugar accumulation biomass enhancement in conferring heavy tolerance. Methods: Commercially available V. seeds were exposed varying concentrations (50, 150, 300 mg/L) mercurous nitrate, lead chloride under controlled conditions. The germination rates, seedling growth, parameters as protein content analyzed using spectrophotometry statistical methods, including ANOVA. Results: results demonstrated that ion increased dry weight, while all tested metals promoted accumulation. Although inhibited at higher concentrations, exhibited strong tolerance moderate levels. Conclusion: highlights adaptive strategies radiata, soluble-sugar-mediated osmotic adjustment enhanced allocation, which contribute its resilience stress. These findings provide insights for breeding stress-resistant crops managing heavy-metal-contaminated environments.

Chickpea (Cicer arietinum L.), a critical diploid legume in the Fabaceae family, is rich source of protein, vitamins, and minerals. However, heavy metal toxicity severely affects its growth, yield, quality. MicroRNAs (miRNAs) play crucial role regulating plant responses to both abiotic biotic stress, including exposure, by suppressing expression target genes. Plants respond stress through miRNA-mediated regulatory mechanisms at multiple physiological, biochemical, molecular levels. Although family well represented miRNA studies, chickpeas have been notably underrepresented. This study aimed investigate effects metal-induced particularly from 100 µM concentrations cadmium (Cd), chromium (Cr), nickel (Ni), lead (Pb), 30 arsenic (As), on two chickpea varieties: ILC 482 (sensitive) Azkan (tolerant). The assessment focused parameters. Furthermore, systematic characterization miR172 gene genome was conducted better understand plant's response stress.
