“…These findings align with previous research that identified pectin as the primary binding site for various heavy metals [ 40 ]. In a separate study, Hou et al discovered that vanadium was predominantly stored in the pectin of cell walls in maize roots, particularly in alkali-soluble pectin, which exhibited the highest vanadium binding capacity [ 19 ]. Similarly, Jia et al found that Cd exposure led to the induction and promotion of pectin-related genes, SIQUA1 and SIPME1, as well as increased activity of pectin methylase [ 16 ].…”

“…One such example is Ricinus communis , which reduces the harmful effects of heavy metals by increasing the absorption of Cd and Zn by adding different functional groups such as –OH, amino, amide, and carboxyl groups to its cell walls [ 15 ]. Certain elements of cell walls, including cellulose, hemicellulose, and others, can also function as sites where heavy metals bind, particularly lignin and pectin [ 16 , 17 , 18 , 19 ].…”

In nature, arbuscular mycorrhizal fungi (AMF) play a crucial role in the root systems of plants. They can help enhance the resistance of host plants by improving the compartmentalization of toxic metal contaminants in the cell walls (CWs). However, the functions and responses of various CW subfractions to mycorrhizal colonization under Cd exposure remain unknown. Here we conducted a study to investigate how Cd is stored in the cell walls of maize roots colonized by Funneliformis mosseae. Our findings indicate that inoculating the roots with AMF significantly lowers the amount of Cd in the maize shoots (63.6 ± 6.54 mg kg−1 vs. 45.3 ± 2.19 mg kg−1, p < 0.05) by retaining more Cd in the mycorrhized roots (224.0 ± 17.13 mg kg−1 vs. 289.5 ± 8.75 mg kg−1, p < 0.01). This reduces the adverse effects of excessive Cd on the maize plant. Additional research on the subcellular distribution of Cd showed that AMF colonization significantly improves the compartmentalization of 88.2% of Cd in the cell walls of maize roots, compared to the 80.8% of Cd associated with cell walls in the non-mycorrhizal controls. We observed that the presence of AMF did not increase the amount of Cd in pectin, a primary binding site for cell walls; however, it significantly enhanced the content of lignin and the proportion of Cd in the total root cell walls. This finding is consistent with the increased activity of lignin-related enzymes, such as PAL, 4CL, and laccase, which were also positively impacted by mycorrhizal colonization. Fourier transform infrared spectroscopy (FTIR) results revealed that AMF increased the number and types of functional groups, including −OH/−NH and carboxylate, which chelate Cd in the lignin. Our research shows that AMF can improve the ability of maize plants to tolerate Cd by reducing the amount of Cd transferred from the roots to the shoots. This is achieved by increasing the amount of lignin in the cell walls, which binds with Cd and prevents it from moving through the plant. This is accomplished by activating enzymes related to lignin synthesis and increasing the exposure of Cd-binding functional groups of lignin. However, more direct evidence on the immobilization of Cd in the mycorrhiza-altered cell wall subfractions is needed.

“…From the viewpoint of subcellular level, vanadium entered the plant cell was mainly bound with the components of the cell wall consist of proteins, cellulose (hemicellulose), lignin, and ligands (e.g., oxhydryl, amidogen, and carboxyl) [13] . Alkali-soluble pectin constitutes the significant vanadium binding site in the cell wall [27] . The bio-reduction of V(V) to V(VI) during plant vanadium uptake is also deemed as a critical vanadium-tolerance mechanism [28,29] .…”

Vanadium is a nontrivial multi-valent metallic element, which has been increasingly used in modern society. The widespread application of vanadium promotes the rapid and sound development of the economy and society, simultaneously brings out increasingly prominent environmental problems, e.g., soil vanadium pollution. Therefore, the remediation problem of vanadium-contaminated soil has been received growing attention. Phytoremediation has become a significant constituent in vanadium-contaminated soil remediation attributable to its veritable merits such as cleanness, esthetics, cost-effectiveness, convenience, and sustainability. Phytoremediation is mainly dependent on hyperaccumulator plants, even though the actuality that the vast majority of hyperaccumulator plants are characterized by low biomass yield and slow-growing. Consequently, the intensity in screening the undiscovered hyperaccumulators should be strengthened. Meanwhile, it is imperative to further explore the vanadium accumulation and translocation characteristics of some non-hyperaccumulative but tolerant plants with moderate biomass to remediate the soil contaminated with vanadium. Taken together, further comprehensive researches of tolerance mechanisms of remedial plants against vanadium are quite necessary to decontaminate soils contaminated by vanadium efficiently.
