“…AtHMA1 is within the chloroplast and zinc anti-toxic while AtH-MA 3 is present in the vacuolar membrane with zinc and cadmium playing a role. The motifs of poplar HMA are very similar to Arabidopsis and rice proteins and it seems that family members of these genes may be functionally divergent due to differences in gene organization and existing motifs (Tian et al 2023). AtHMA 1 and 2 are in the plasma membrane and in zinc and cadmium fluxes.…”

“…HMAs interact with metal chelators, such as phytochelatins (PCs), which are small peptides that bind to heavy metal ions, including Cd. This process contributes to the detoxification and sequestration of cadmium in less sensitive cellular compartments (Tian et al, 2023).…”

Heavy metal contamination can have a strong effect on the morphological and physiological characteristics of plants. In the present study, Cicer arietinum L. (chickpea) was exposed to different concentrations of cadmium (control, 2, 4, 8 μg Cd g-1 perlite) and the effect on plant growth and antioxidant enzymes were evaluated. The observed morphological changes in chickpea plant included stunted growth, reduced root system development and plant color change. A significant increase in enzyme activity of peroxidase, superoxide dismutase, catalase, and ascorbate peroxidase was observed at 4 μg Cd g-1 perlite, with a subsequent decrease when concentration was increased to 8 μg Cd g-1 perlite in the leaves of the plants. The highest cadmium levels were determined at a concentration of 8 μg Cd g-1 perlite. With the addition of 2 μg Cd g-1 perlite, manganese uptake in the aboveground part of the plant increased significantly, but then decrease at higher cadmium concentrations. In addition, zinc and copper levels decrease in the presence of cadmium. These results indicate that chickpea has a relatively high adsorption capacity for cadmium in aboveground tissues and special precautions should be taken when growing chickpea. In silico analysis led to the identification of 13 heavy metal ATPases (HMAs) in chickpea. These proteins contain 130 to 1032 amino acids with 3 to 18 exons. They are involved in the transfer of cadmium and zinc and help in heavy metal detoxification of plants. Bioinformatics studies have been conducted to better understand the mechanism by which the plant is able to combat heavy metal stress.

“…Many works have been conducted to clarify the role of individual isogene on the transport of specific HMs in plants [ 13 ]. The competition between Cd and Zn/Cu was different to the competition between Cd and Fe/Mn in rice seedlings during metal transport within rice tissues, which is likely due to the difference in transporters and associated genes [ 14 ]. The HMs P1B-ATPases genes located in plasma membrane and tonoplast play more important role in metal translocation and storage within plant tissues than other proteins identified [ 14 ].…”

Heavy metals such as cadmium (Cd) and zinc (Zn) could be dangerous and pollute the environment due to their high migration ability, robust bioavailability, and acute toxicity to soil biota and plants. Considering the above characteristics of these elements, the study’s aim was to explore the individual and combined impact of Cd and Zn contamination of Haplic Chernozem on growing two-row spring barley (Hordeum vulgare L.). The accumulation and distribution of Cd and Zn in various parts of H. vulgare have also been studied, which showed that Cd accumulation by H. vulgare occurred more intensely than that by Zn up to eight times. Cadmium and Zn suppress plant growth up to two times, more effect was noted by the combined impact of Cd and Zn. The study of plant morphological characteristics revealed that growth suppression and structural changes in the root and leaf tissues increased in proportion to Cd and Zn concentrations. Detailed analysis of the localizations of Zn and Cd in various organelles of H. vulgare cells was performed. Heavy metals change the ultrastructure of prominent energy-producing organelles in leaf cells, especially chloroplasts and mitochondria. Overall, the current findings offer insights into phytotoxicity induced by Cd and Zn individual application as well as in combination with the H. vulgare plant. Zinc showed protective effects against high doses of Cd under the combined application. These antagonistic interactions reduce their accessibility to H. vulgare. The present work can be useful in restricting the entry of these elements into the food chain and preventing creating a threat to human health.
