“…They may also be involved in the transportation of non-essential and highly toxic HMs, such as Cd. Jiang et al (2021) who explored the function of an SmZIP gene isolated from Salix matsudana and its role in Cd tolerance, uptake, translocation, and distribution [ 55 ]. By overexpressing the SmZIP transporter in transgenic tobacco, they found that Cd-stress-induced phytotoxic effects were reduced compared to WT plants.…”

“…The overexpression of SmZIP resulted in the redistribution of Cd at the subcellular level, a decrease in the percentage of Cd in the cell walls, and an increase in Cd in the soluble fraction of both roots and leaves. Thus, the overexpression of SmZIP plays important roles in Cd accumulation and translocation, subcellular distribution, and chemical forms in transgenic tobacco under Cd stress [ 55 ].…”

Soil metal contamination associated with productive activities is a global issue. Metals are not biodegradable and tend to accumulate in soils, posing potential risks to surrounding ecosystems and human health. Plant-based techniques (phytotechnologies) for the in situ remediation of metal-polluted soils have been developed, but these have some limitations. Phytotechnologies are a group of technologies that take advantage of the ability of certain plants to remediate soil, water, and air resources to rehabilitate ecosystem services in managed landscapes. Regarding soil metal pollution, the main objectives are in situ stabilization (phytostabilization) and the removal of contaminants (phytoextraction). Genetic engineering strategies such as gene editing, stacking genes, and transformation, among others, may improve the phytoextraction potential of plants by enhancing their ability to accumulate and tolerate metals and metalloids. This review discusses proven strategies to enhance phytoextraction efficiency and future perspectives on phytotechnologies.

“…2C -D). Previous studies have also shown that the roots could be the highest Cd content parts of plants 23,24 because roots are the primary organs in the response to Cd stress in soil and Cd can complex with proteins, cellulose or pectates, or insoluble Cd-phosphate in the root cell wall 25 . This characteristic of Cd uptake of roots is consistent with the accumulation of heavy metals in root-hoarding plants.…”

Chinese herbal medicine is widely cultivated in southwest China where the soil cadmium (Cd) contamination of farmland is more serious than that in the whole of China. In this study, Polygonatum sibiricum were exposed to Cd at the concentrations of e− 1, e0, e2, and e4 mg·kg− 1 for up to 30,60, and 90 days and their physiological stress responses, Cd and mineral element uptake, antioxidant enzyme activities, and content changes of pharmaceutical ingredients (polysaccharides) were analyzed to decipher the feasibility of safety use in Cd contaminated soil. Results showed that the activity of antioxidant enzymes (SOD, POD, and CAT) of the aboveground part was enhanced in response to Cd stress after 90 d. Compared with the control, the underground part mobilizes non-enzymatic systems to facilitate the synthesis of polysaccharides (PCP1, PCP2) with antioxidant properties to cope with Cd stress. Mineral elements (P, K, Ca, Mg, Fe, Cu, and Zn) were significantly changed after 90 d of cultivation. In particular, the changes in iron and zinc contents were significantly correlated with the activities of SOD and POD. The soil Cd safety thresholds value for Polygonatum sibiricum is e0 mg·kg− 1, under which concentration the stimulation of Cd promotes polysaccharides synthesis and biomass growth.

“…The chemical form approach quantifies the metal fates within cells by sequentially extracting metals with different chemical solutions ( Jiang et al, 2021 ). Although these chemical phases are operationally defined, studies have provided clear evidence that heavy metals in inorganic form and water-soluble form migrate more readily than metals binding to pectates, phosphates, and oxalates, and these forms have stronger negative effects on plant cells.…”

Daucus carota is a biennial herb of the Umbelliferae family, which is a candidate plant for the phytoremediation of Mn pollution. To reveal the mechanism of this plant to adapt to Mn stress, plant growth, anatomical structure, Mn accumulation characteristic, Mn subcellular distribution, and chemical forms of D. carota under six Mn2+ concentrations by pot culture experiments were studied. The results showed that with the rising Mn concentrations, the total dry weight and leaf area of D. carota increased firstly and then decreased, while the specific leaf area increased. The thickness of the main vein, upper epidermis, and lower epidermis; the thickness of the palisade tissue; and the thickness of the spongy tissue of the leaves increased firstly and then decreased. The Mn content in the aboveground and underground parts of D. carota increased, and the values of the bioconcentration factor (BCF) and translocation factor (TF) were higher than 1. The Mn existing in the cell wall and soluble components accounted for the largest proportion, and the proportion of Mn in the cell wall increased with increasing concentrations of Mn. In addition, Mn mainly existed in ethanol extraction state, deionized water extraction state, and sodium chloride extraction state. The results showed that D. carota could alleviate the damage caused by high manganese concentration by storing most of manganese in the cell wall and vacuole and existing in the form of low-activity state.
