“…These findings suggest that Ca +2 interact with cellular mechanisms associated with vacuolar sequestration upon Cr exposure through PC synthesis regulation in the roots of rice plants to withstand Cr toxicity. Similar type of result was also found in rice after applying silicon and salicylic acid under chromium stress (Huda et al 2016(Huda et al , 2017.…”

Heavy metal chromium (Cr) is considered to be a serious environmental contaminant due to its toxic effect on living organisms. To mitigate and reduce the negative impacts of Cr in rice plant, the effect of exogenous supplementary calcium was evaluated as it functions as a signaling molecule at cellular level. In this study, growth parameters, protein content, and membrane stability were found to be restored due to calcium under Cr stress. Further, Atomic absorption spectrophotometric analysis revealed that calcium inhibits Cr translocation from root to shoot in rice seedlings. This event was addressed by the enhanced accumulation of phytochelatin that leads to vacuolar sequestration of Cr in roots. Furthermore, increased activity of Catalase, Peroxidase, and Glutathione reductase along with elevated glutathione also assures that calcium enhances antioxidant defense mechanism to cope with Cr toxicity.

“…Iron enriched growth medium significantly reduced Cr(VI)-uptake and translocation in plants [170]. The pretreatment of seeds with salicylic acid, application of auxin and ethylene inhibitors to growth media, treatment of polyamine-brassinosteroid, 24-epibrassinolide, and plant growth-promoting bacteria reduce Cr-uptake, translocation, and toxicity [8,30,42,48,68,123,171]. The natural selection of Cr-tolerant varieties, conventional breeding, and targeted genes mutation can be used for the control of Cr-phytotoxicity and damage to yield of economically important crops.…”

Chromium (Cr) is one of the top seven toxic heavy metals, being ranked 21st among the abundantly found metals in the earth’s crust. A huge amount of Cr releases from various industries and Cr mines, which is accumulating in the agricultural land, is significantly reducing the crop development, growth, and yield. Chromium mediates phytotoxicity either by direct interaction with different plant parts and metabolic pathways or it generates internal stress by inducing the accumulation of reactive oxygen species (ROS). Thus, the role of Cr-induced ROS in the phytotoxicity is very important. In the current study, we reviewed the most recent publications regarding Cr-induced ROS, Cr-induced alteration in the enzymatic antioxidant system, Cr-induced lipid peroxidation and cell membrane damage, Cr-induced DNA damage and genotoxicity, Cr-induced ultrastructural changes in cell and subcellular level, and Cr-induced alterations in photosynthesis and photosynthetic apparatus. Taken together, we conclude that Cr-induced ROS and the suppression of the enzymatic antioxidant system actually mediate Cr-induced cytotoxic, genotoxic, ultrastructural, and photosynthetic changes in plants.

“…Moreover, phytochelatins became larger as the molecular polymers lengthened with increasing repetitions of the (γ‐Glu‐Cys) units following treatment with salicylic acid and Cd exposure. Phytochelatin content and phytochelatinS transcripts were also enhanced in chromium (Cr)–exposed O. sativa supplemented with salicylic acid (Huda et al 2016). However, not all studies observed this effect of salicylic acid; Metwally et al (2003) found that neither the content of GSH nor phytochelatin synthase gene expression was significantly different under Cd stress when treated with salicylic acid.…”

Heavy metals can represent a threat to the health of aquatic ecosystems. Unlike organic chemicals, heavy metals cannot be eliminated by natural processes such as their degradation into less toxic compounds, and this creates unique challenges for their remediation from soil, water, and air. Phytoremediation, defined as the use of plants for the removal of environmental contaminants, has many benefits compared to other pollution-reducing methods. Phytoremediation is simple, efficient, cost-effective, and environmentally friendly because it can be carried out at the polluted site, which simplifies logistics and minimizes exposure to humans and wildlife. Macrophytes represent a unique tool to remediate diverse environmental media since they can accumulate heavy metals from contaminated sediment via roots, from water via submerged leaves, and from air via emergent shoots. In this review, a synopsis is presented about how plants, especially macrophytes, respond to heavy metal stress and we propose potential roles that phytohormones can play in the alleviation of metal toxicity in the aquatic environment. We focus on the uptake, translocation, and accumulation mechanisms of heavy metals in organs of macrophytes and give examples of how phytohormones interact with plant defense systems under heavy metal exposure. We advocate for a more in-depth understanding of these processes to inform more effective metal remediation techniques from metal-polluted waterbodies.
