“…The exposure of plants to heavy metals might increase the activity of anti-oxidants; however, the very high metal concentration might destroy the protective enzymes system, and thereby decreases the antioxidant activities [ 64 ]. The antioxidant enzymes (CAT, POD, and APX) activity was markedly increased under Cd stress.…”

Cadmium (Cd) toxicity is a serious environmental issue causing a significant reduction in crop growth and productivity globally. Trehalose (Tre) has emerged as an important reducing sugar that can reduce the adverse impacts of different abiotic stresses. Therefore, the present investigation was performed to determine the key role of Tre in alleviating Cd stress in the mung bean (Vigna radiata L.) crop. The study was comprised of different treatments of cadmium (0, 10, 20 mg kg−1 soil) and Tre (0, 15 and 30 mM). Cd stress significantly restricted the growth and yield of mung bean. However, Tre supplementation markedly improved growth and yield due to pronounced reductions in Cd uptake and Cd-induced oxidative stress as shown by the lower production of hydrogen peroxide (H2O2), electrolyte leakage (EL) and malondialdehyde (MDA) in Cd-stressed plants as well as by the enhanced activities of antioxidant enzymes (CAT, POD, APX and AsA). Moreover, the ameliorative role of Tre to Cd toxicity was also demonstrated by its ability to enhance chlorophyll contents, total soluble protein (TSP) and free amino acids (FAA). Taken together, Tre supplementation played a key beneficial role in improving Cd stress tolerance and yield traits of mung bean through restricting Cd uptake and enhancing photosynthetic capacity, osmolytes biosynthesis and antioxidant activities.

“…the hormonal status of tissues, tissue type and heavy metal uptake. The regulation of gene expression represents the first level of integration between environmental stress and the genome [30]. Ramie is a perennial herb plant with developed underground roots, a high accumulation of heavy metal Cd 2+ and BnMTL expression in roots rather than stems or leaves, consistent with the fact that the roots are the main organ for this species to adapt to a stress environment [31].…”

Ramie ( Boehmeria nivea ) is a perennial herb that is highly tolerant of heavy metals. In the present study, we cloned a novel metallothionein‐like gene from ramie; this gene, termed Bn MTL , encodes a putative 46 amino acid protein with a molecular mass of 4.38 kD a. Analysis using quantitative RT ‐ PCR revealed that cadmium (Cd 2+ ) treatment results in elevated expression of Bn MTL in the roots. We heterologously overexpressed Bn MTL in Escherichia coli cells to examine its binding to Cd 2+ and its possible role in homeostasis. Recombinant E. coli cells expressing Bn MTL exhibited a high tolerance of Cd 2+ stress up to a concentration of 1 m m , and the observed accumulation of Cd 2+ was almost eight‐fold higher than the control. These results demonstrate that Bn MTL (i) is highly expressed in the root following exposure to Cd 2+ and (ii) encodes a typical metallothionein‐like protein with high cadmium‐binding activity.

“…Rapid industrial development in past two centuries has caused a significant contribution to soil and water contamination, primarily with heavy metals and organic pollutants [1]. Strategies for environmental clean-up technologies require not only reliable tools but also precise approaches and procedures that are cost-efficient and possible to use during large scale remediation programs subjected to continually changing conditions [2].…”

“…In the past, technologies aimed for developing specific approaches to use plants as bioindicators and then to use such species for remediation were strictly focused on using standard toxicity tests in order to evaluate the level of phytotoxicity and the level of persistence of selected contaminant in plants tissues [11]. For future improvement and optimization of any phytoremediation activities, the precise identification of metabolic mechanisms involved in contaminant tolerance, uptake and detoxification is required [1]. These consist of extremely complex cellular systems and pathways controlled by large families of genes.…”

Wdrożenie badań omicznych w celu zwiększenia efektywności fitoremediacji -przeglądPhytoremediation is recognized as a cost-effective and widely acceptable alternative to chemical and physical technologies of soil remediation but requires an overall longer time to achieve success. In the last decade, the vast progress in omics research had led to improvements in our understanding of plants metabolism under exposure to toxic substances and the interactions between microbial communities and plants. Omics research includes a number of disciplines aimed at explaining the biological and chemical principles of functioning a particular organism exposed to selected factors using modern methods of molecular biology (example: rt-qPCR -Quantitative polymerase chain reaction in real time). The names of individual branches of omics studies arise from a group of studied substances, example: transcriptomic refers to research related to changes occurring in the organism at the level of its transcriptome, and proteomics deals with the determination of complete information on the proteomic composition of a given sample. By merging available omics tools with new bioinformatic approaches, it is possible to understand and determinate the specific patterns of plants response to various stress factors. In this review, we provide an overview of how omics research including transcriptomic, proteomic, genomic and metagenomic approaches might be used to reduce the negative impact of toxic elements to plants growth and development in order to ultimately enhance the phytoremediation efficiency.
