“…Metal chelate complexes, e.g., PCs, amino acids, glutathione, and MTs, play a significant role in controlling metal toxicity [ 96 ]. The protein-based phytoremediation has the potential to control the HMs in polluted lands [ 200 ]. Biotechnology-based remediation techniques are indicated in Table 2 .…”

Heavy metals (HMs) normally occur in nature and are rapidly released into ecosystems by anthropogenic activities, leading to a series of threats to plant productivity as well as human health. Phytoremediation is a clean, eco-friendly, and cost-effective method for reducing soil toxicity, particularly in weedy plants (invasive plant species (IPS)). This method provides a favorable tool for HM hyperaccumulation using invasive plants. Improving the phytoremediation strategy requires a profound knowledge of HM uptake and translocation as well as the development of resistance or tolerance to HMs. This review describes a comprehensive mechanism of uptake and translocation of HMs and their subsequent detoxification with the IPS via phytoremediation. Additionally, the improvement of phytoremediation through advanced biotechnological strategies, including genetic engineering, nanoparticles, microorganisms, CRISPR-Cas9, and protein basis, is discussed. In summary, this appraisal will provide a new platform for the uptake, translocation, and detoxification of HMs via the phytoremediation process of the IPS.

“…Furthermore, plant species vary widely in their capacity to adsorb and accumulate metals in harvestable parts, with hyperaccumulator species being particularly useful for these purposes (Ghazaryan et al, 2021). However, in most cases soils are contaminated by several metals, whereas hyperaccumulator species absorb high concentrations of a particular metal, with other metals remaining in the soil.…”

Phytoextraction has been proposed in many papers as a low-cost method for remediating contaminated soil. However, if national regulation is based on total metal(loid) concentrations in soil, phytoextraction is generally infeasible because of the long time required for remediation. Assessing phytoextraction requires determination of the dynamic rate of metal removal from soil. Phytoextraction may be feasible if the main goal is to reduce the soluble fraction of the metal(loid) with the goal of reducing bioavailability. However, it has been reported that there is a large mass balance mismatch between the reduction of the soluble metal fraction in contaminated soil and metal uptake by plants. Several studies report that the decrease of soluble fraction of metals in soil is higher than can be accounted for by plant uptake. In other words, studies generally overestimate the feasibility of bioavailable contaminant stripping. Therefore, a more rigorous approach is advisable to ensure that papers on bioavailable contaminant stripping include relevant information on mass balances. Furthermore, to implement the concept of bioavailable contaminant stripping, regulations must distinguish between the bioavailable fraction and the total metal concentration in soil.

“…In general, a chelating agent is a chemical reagent used to enhance the bioavailability of various PTEs in the soil such as Cu, Pb, Cd and others for metal translocation into a plant (Rena et al, 2022;Yang et al, 2021b). The limitations in the standard phytoremediation procedure, such as low decontamination rate, low bioavailability of targeted metals and reduction of plant growth due to metal toxicity, have led to many new scientific studies to enhance phytoremediation for PTEs clean-up in the soil (Ghazaryan et al, 2021;Gul et al, 2021). The chelating agents act as a chemical bond to form metal complex(es) which help to enhance the bioavailability of PTEs in the soil and facilitate the phytoremediation process for metal translocation into the roots and aboveground part of the plants (Huang et al, 2019;Rena et al, 2022).…”

“…Table 6 lists chelating agents used in phytoremediation for different metal types and plants. Based on previous studies, the application of chelating agents in phytoremediation technology has proven to improve the phytoremediation potential for diverse types of metals and plants in terms of PTEs accumulation (Huang et al, 2019;Rena et al, 2022;Tahmasbian and Safari Sinegani, 2016), plant growth (Aghelan et al, 2021;Ghazaryan et al, 2021) and microbial community in soil (Gul et al, 2021)..…”

“…Global advancements with expanding industrial and human activities have dramatically resulted in several pollution in the soil. Soil pollution is a critical worldwide environmental problem due to its pronounced effects on the ecosystem and human health (Cristaldi et al, 2017;Ghazaryan et al, 2021). Due to the presence of various mutagenic and carcinogenic elements in the soil, soil contamination has brought several negative impacts to the ecosystem, such as deterioration of plant growth and PTEs accumulation in animals and consequently led to the food chain contamination at higher trophic levels (Shah and Daverey, 2020;Shen et al, 2022;Yadav et al, 2018).…”
