“…Similar effect was observed in Nocceae caerulescens, in which combined treatments of Zn (500 M) and Cd (200 M) in hydroponic cultures resulted in increasing Cd 2+ influx into root tissues and higher accumulation in shoots (Papoyan et al, 2007), and this response has been associated with hyperaccumulator phenotypes (Lasat et al, 1998;Papoyan and Kochian, 2004). Moreover, the hyperaccumulator Brassica juncea had an increase in Cd uptake after Zn addition, leading also to a higher tolerance in comparison to plants exposed to Cd and Zn separately (Kutrowska et al, 2017). In field conditions, positive correlation between Zn and Cd accumulation in shoots was also reported in Cacao trees (Arévalo-Gardini et al 2017).…”

Metal inputs to terrestrial ecosystems are of great concern due their toxicity to biota, especially for elements with no biological function such as cadmium. Fast-growing trees such as poplars may have potential in phytoremediation schemes. We assessed accumulation, metal partitioning, gene expression (Pt-HMA4) and overall tolerance to, and interaction between, cadmium (Cd) and zinc (Zn) in Populus trichocarpa 'Trichobel'. We predicted that Zn would have an antagonistic effect in Cd accumulation and anticipated some level of tolerance to these metals. Poplars were grown in sandy substrate under different metal applications, ranging from 1 to 243 mg kg-1 Cd; or 30 to 7,290 mg kg-1 Zn; and also two combined treatments: 27 mg kg-1 Cd with 90 or 270 mg kg-1 Zn. Growth parameters and metal contents in shoots and roots were determined. Transcriptional levels of the Pt-HMA4 gene were assessed in roots and leaves. P. trichocarpa showed a surprisingly high tolerance to Cd, with root biomass being affected only at the highest doses applied. Metals accumulated mainly in roots (up to 6,537 mg kg-1 Cd and 21,500 mg kg-1 Zn), root-to-shoot translocation peaked at the 9 mg kg-1 dose for Cd (41%) and 90 mg kg-1 for Zn (40%). At high Cd/Zn applications, expression of Pt-HMA4 in roots decreased significantly. Contrary to the initial presumption, Zn addition increased Cd uptake, reaching hyperaccumulator-like concentrations in shoots (≥ 100 mg kg-1 Cd). Differential root-to-shoot partitioning has a major role in Cd tolerance in P. trichocarpa; partly by down-regulating the Pt-HMA4 gene in roots. Zn addition promoted high Cd uptake without any detriment to plant growth. P. trichocarpa was tolerant to extreme Cd concentrations, offering a great potential to be used in phytoremediation techniques for stabilization/extraction of Cd from soils contaminated by both Cd and Zn.

“…Cd ecotoxicity induced low biomass of crops compensated by very high metal concentrations in the shoots and roots [7][8][9][10]. Crops in agricultural soil take up Cd from the soil pore water, while the uptaking content was usually associated with the concentration of total Cd in soil solution [11][12][13][14]. Cd accumulation in plants has been extensively studied, however, the mechanism by which Cd toxicity causes plant tissue injure are not yet fully understood.…”

“…The metal concentrations followed an order of Pb>Cu>Zn>Cd in roots, Zn>Cu>Pb>Cd in the stem and Zn>Cu>Cd>Pb in leaves (Kutrowska et al, 2017). Based on the obtained results, it can be concluded that B. juncea is a hyperaccumulator of Cd, Zn and Pb.…”

“…Cherif and co-authors (2011) reported that Zn induced a decrease in Cd uptake and a simultaneous increase in Zn accumulation, indicating a strong competition between these two metals for the same membrane transporters. In our earlier study (Kutrowska et al, 2017) Cd, Pb and Hg, have been shown to cause protein oxidation by depletion of protein thiol groups (Sharma et al, 2012). ROS cause protein modifications through the formation of carbonyl groups at certain amino acid residues.…”

Metal hyperaccumulating plants should have extremely efficient defence mechanisms, enabling growth and development in a polluted environment. Brassica species are known to display hyperaccumulation capability. Brassica juncea (Indiana mustard) v. Malopolska plants were exposed to trace elements, i.e., cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn), at a concentration of 50 M and were then harvested after 96 hours for analysis. We observed a high index of tolerance (IT), higher than 90%, for all B. juncea plants treated with the four metals, and we showed that Cd, Cu, Pb and Zn accumulation was higher in the above-ground parts than in the roots. We estimated the metal effects on the generation of reactive oxygen species (ROS) and the levels of protein oxidation as well as on the activity and gene expression of antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX). The obtained results indicate that organo-specific ROS generation was higher in plants exposed to essential metal elements (i.e., Cu and Zn), compared with non-essential ones (i.e., Cd and Pb), in conjunction with SOD, CAT and APX activity and expression at the level of encoding mRNAs and existing proteins. In addition to the potential usefulness of B. juncea in the phytoremediation process, the data provide important information concerning plant response to the presence of trace metals.
