“…Therefore, the combined plant-microbes method can improve the heavy metal resistance of plants and achieve an ideal remediation effect. In recent years, it has also been found the limited efficiency of phytoremediation with a single plant (Buscaroli et al, 2017;Rizwan et al, 2019;Hosseinniaee et al, 2022) and the co-planting pattern of complementary plants for metals enrichment may be more efficient. The co-plantation of Solanum nigrum with Quercus nuttallii or Quercus pagoda effectively improved the enrichment of cadmium (>40%) and zinc (>30%) (Qu et al, 2021).…”

Heavy metals (HMs) contamination and vegetation destruction in the mining area caused by mining activities are severely increasing. It is urgent to restore vegetation and stabilize HMs. In this study, we compared the ability of HMs phytoextraction/phytostabilization of three dominant plants, including Artemisia argyi (LA), Miscanthus floridulus (LM), and Boehmeria nivea (LZ) in a lead-zinc mining area in Huayuan County (China). We also explored the role of the rhizosphere bacterial community in assisting phytoremediation using 16S rRNA sequencing technology. Bioconcentration factor (BCF) and translocation factor (TF) analysis showed that LA preferred accumulating Cd, LZ preferred accumulating Cr and Sb, and LM preferred accumulating Cr and Ni. Significant (p < 0.05) differences were found among the rhizosphere soil microbial communities of these three plants. The key genera of LA were Truepera and Anderseniella, that of LM were Paracoccus and Erythrobacter, and of LZ was Novosphingobium. Correlation analysis showed some rhizosphere bacterial taxa (e.g., Actinomarinicola, Bacillariophyta and Oscillochloris) affected some soil physicochemical parameters (e.g., organic matter and pH) of the rhizosphere soil and enhanced the TF of metals. Functional prediction analysis of soil bacterial community showed that the relative abundances of genes related to the synthesis of some proteins (e.g., manganese/zinc-transporting P-type ATPase C, nickel transport protein and 1-aminocyclopropane-1-carboxylate deaminase) was positively correlated with the phytoextraction/phytostabilization capacity of plants for heavy metals. This study provided theoretical guidance on selecting appropriate plants for different metal remediation applications. We also found some rhizosphere bacteria might enhance the phytoremediation of multi-metals, which could provide a reference for subsequent research.

“…There has been a growing concern regarding heavy metals pollution, which is primarily the result of anthropogenic activities such as smelting and mining, e uents discharging, solid waste disposal and industrial waste treatment (Ibrahim et al, 2017;Thuan et al, 2018;Guo et al, 2019). A negative effect of potentially toxic metals on soil microbial populations can result in a reduction of biological activity and it has been shown that a heavy metal's absorption and accumulation inhibit plant growth; these metals also interfere with root and leaf development (Tauqeer et al, 2019;Hosseinniaee et al, 2022). Heavy metal stress triggers a multitude of complex plant reactions; these mechanisms involve the concept of irritant as well as antioxidant defense mechanisms (Rehman et al, 2019;Saleem et al, 2020).…”

This study aims to evaluate the enhancement of phytoextraction of heavy metals Pb, Cd and Zn by species M. cuneatum, S. arabica and V. speciosum, through EDTA amendment. Assisted phytoextraction pot experiments were performed at different EDTA dosages (0, 1, 3 and 5 mmol kg-1 soil). Generally, applying EDTA decreased pH and increased EC, while no significant effect was observed on organic matter, nitrogen, and exchangeable K and P. Also the activity of soil dehydrogenase enzyme was inhibited at 5 mmol kg-1 EDTA. The phytoavailability of Cd, Pb and Zn increased significantly in the presence of EDTA, followed by the contents of them in the tissues of all three studied species amplified. Resulting from oxidative stress caused by the accumulation of metals, the activity of antioxidant enzymes such as, glutathione peroxidase (GPX), superoxide dismutase (SOD) and catalase (CAT) increased, when chelating agent was added. EDTA showed fluctuating effect on malondialdehyde (MDA) content and in higher doses it partially decreased chlorophyll concentration. EDTA at the level of 1 and 3 mmol kg-1 enhanced the plant growth, but 5 mmol kg-1 of that reduced the biomass of the studied species. The Bioconcentration factor (BCF) for Cd was notably high in all studied plants, and considerably elevated for Zn and Pb with the addition of EDTA in M. cuneatum and S. arabica (BCF>1), whilst accumulation factor greater one (AF>1) were found for Cd in all species and for Pb in the case of S. arabica. Predictive models for metal accumulation in plant tissues were developed using stepwise multiple linear regression, with pH and Cd showing the highest contribution to interpretation and variability of the dependent variables. In general, the results demonstrated that EDTA can be an effective amendment for phytoextraction of Cd, Zn and Pb by M. cuneatum, V. speciosum and S. arabica in contaminated soils.
