“…Soil heavy metal pollutions have become a severe problem in many parts of the world (Cui et al 2017;Facchinelli et al 2001;Kovacs and Szemmelveisz 2017;Li et al 2014;. In response, various remediation techniques have been developed to decontaminate the heavy metal polluted soils (Chen et al 2015;Lu et al 2014;Qiao et al 2017;Radu et al 2015).…”

Ethylenediaminetetraacetic acid (EDTA) used with electrokinetic (EK) to remediate heavy metal-polluted soils is a toxic chelate for soil microorganisms. Therefore, this study aimed to evaluate the effects of alternative organic chelates to EDTA on improving the microbial properties of a heavy metal-polluted soil subjected to EK. Cow manure extract (CME), poultry manure extract (PME) and EDTA were applied to a lead (Pb) and zinc (Zn)-polluted calcareous soil which were subjected to two electric intensities (1.1 and 3.3 v/cm). Soil carbon pools, microbial activity, microbial abundance (e.g., fungal, actinomycetes and bacterial abundances) and diethylenetriaminepentaacetic acid (DTPA)-extractable Pb and Zn (available forms) were assessed in both cathodic and anodic soils. Applying the EK to soil decreased all the microbial variables in the cathodic and anodic soils in the absence or presence of chelates. Both CME and PME applied with two electric intensities decreased the negative effect of EK on soil microbial variables. The lowest values of soil microbial variables were observed when EK was combined with EDTA. The following order was observed in values of soil microbial variables after treating with EK and chelates: EK + CME or EK + PME > EK > EK + EDTA. The CME and PME could increase the concentrations of available Pb and Zn, although the increase was less than that of EDTA. Overall, despite increasing soil available Pb and Zn, the combination of EK with manures (CME or PME) mitigated the negative effects of using EK on soil microbial properties. This study suggested that the synthetic chelates such as EDTA could be replaced with manures to alleviate the environmental risks of EK application.

“…Previously, we have noted Cd accumulation in roots of plants treated with 100 µM CdSO 4 for 1 h and an increase in Cd accumulation in leaves during the next 7 d (Repkina et al 2015). This is typical for wheat as well as for some other plants species which mainly accumulate heavy metals in roots for preventing their entry into the aboveground parts (Kovacs and Szemmelveisz 2017). Nevertheless, cadmium exposure led to a decrease in wheat fresh mass accumulation but less compared with the low temperature ( Table 1).…”

“…Pb in soil, is easily transferred to plant tissues, can not only influence various morphological, physiological and biochemical processes in plant, can also threats to human health through food chains [3][4][5]. Several alleviating techniques such as phytoremediation (including Phytostabilization and Phytoextraction) have been applied for safe utilization of Pb contaminated soil [6,7]. Development of new cultivars tolerance to Pb toxicity will be the first step for safe utilization of Pb polluted soil by phytoremediation [8][9][10].…”

Background: Lead (Pb) pollution in soil has become one of the major environmental threats to plant growth and human health. Safe utilization of Pb contaminated soil by phytoremediation require Pb-tolerant rapeseed (Brassica napus L.) accessions. However, breeding of new B. napus cultivars tolerance to Pb stress has been restricted by limited knowledge on molecular mechanisms involved in Pb tolerance. This work was carried out to identify genetic loci related to Pb tolerance during seedling establishment in rapeseed. Results: Pb tolerance, which was assessed by quantifying radicle length (RL) under 0 or 100 mg/L Pb stress condition, shown an extensive variation in 472 worldwide-collected rapeseed accessions. Based on the criterion of relative RL > 80%, six Pb-tolerant genotypes were selected. Four quantitative trait loci (QTLs) associated with Pb tolerance were identified by Genome-wide association study. The expression level of nine promising candidate genes, including GSTUs, BCATs, UBP13, TBR and HIPP01, located in these four QTL regions, were significantly higher or induced by Pb in Pb-tolerant accessions in comparison to Pb-sensitive accessions.Conclusion: To our knowledge, this is the first study on Pb-tolerant germplasms and genomic loci in B. napus. The findings can provide valuable genetic resources for the breeding of Pb-tolerant B. napus cultivars and understanding of Pb tolerance mechanism in Brassica species.
