“…Under Zn or Cd stress, the relative expression of two phytochelatin synthase genes from Morus alba was induced in root, stem and leaf tissues within 24 h of exposure to the metals, with Cd inducing expression more strongly than did Zn ( Fan et al, 2018 ). The expression level of SoPCS were significantly unregulated in Saccharum officinarum roots under cadmium stress ( Yousefi et al, 2018 ). The MT2 and PCS1 gene expression patterns in Azolla species were significantly induced by the heavy metal treatments (Cu, Zn, Ni, and Cd) ( Talebi et al, 2019 ).…”

Phytochelatins (PCs) play important roles in the detoxification of and tolerance to heavy metals in plants. The synthesis of PCs is catalyzed by phytochelatin synthase (PCS), which is activated by heavy metal ions. In this study, we isolated a PCS gene, BnPCS1, from the bast fiber crop ramie (Boehmeria nivea) using the RACE (rapid amplification of cDNA ends) method. The full-length BnPCS1 cDNA is 1,949 bp in length with a 1,518 bp open reading frame (ORF) that encodes a 505 amino acid protein. The deduced BnPCS1 protein has a conserved N-terminus containing the catalytic triad Cys58, His164, Asp182, and a flexible C-terminal region containing a C371C372QETC376VKC379 motif. The BnPCS1 promoter region contains several cis-acting elements involved in phytohormone or abiotic stress responses. Subcellular localization analysis indicates that the BnPCS1-GFP protein localizes to the nucleus and the cytoplasm. Real-time PCR assays show that the expression of BnPCS1 is significantly induced by cadmium (Cd) and the plant hormone abscisic acid (ABA). Overexpression lines of BnPCS1 exhibited better root growth and fresh weight, lower level of MDA and H2O2, and higher Cd accumulation and translocation factor compared to the WT under Cd stress. Taken together, these results could provide new gene resources for phytoremediation of Cd-contaminated soils.

“…contains thirteen species [49]. Sugarcane (Saccharum officinarum L.) is a recognized phytoremediation plant due to its biomass abundance, fast growth, and moderate uptake and accumulation of heavy metals such as Cu, Cd, Se, Pb, and Mn [50][51][52]. The Saccharum officinarum L. plant was found to be a good phytoremediator of lindane-rich garden soil, with degraded 600 mg L -1 of lindane.…”

Fossil fuel depletion and soil and water pollution gave impetus to the development of a novel perspective of sustainable development. In addition to the use of plant biomass for ethanol production, plants can be used to reduce the concentration of heavy metals in soil and water. Due to tolerance to high levels of metals, many plant species, crops, non-crops, medicinal, and pharmaceutical energy plants are well-known metal hyperaccumulators. This paper focuses on studies investigating the potential of Miscanthus sp., Beta vulgaris L., Saccharum sp., Ricinus communis L. Prosopis sp. and Arundo donax L. in heavy metal removal and biofuel production. Phytoremediation employing these plants showed great potential for bioaccumulation of Co, Cr, Cu, Al, Pb, Ni, Fe, Cd, Zn, Hg, Se, etc. This review presents the potential of lignocellulose plants to remove pollutants being a valuable substrate for biofuel production. Also, pretreat-ments, dealing with toxic biomass, and biofuel production are discussed.

Solanaceous plants are ubiquitous and are able to colonize degraded, abandoned and metal polluted habitats. Members of the family have evolved interesting extrinsic and intrinsic traits to combat the metal toxicity in multiple ways. Indumentum constituted mostly of trichome layer provides structural defense for both biotic stress (herbivory, oviposition, microbial pathogenesis) and abiotic stress (like drought, heat, freezing, photooxidation and UV radiation). Plants with heavy metal tolerance can accumulate toxic heavy metals in their trichomes as a part of their elemental defense detoxification strategy. Apart from the canonical functions, trichomes support ion and metal homeostasis, including the sequestration, compartmentalization, accumulation and excretion of heavy metals in many ways. The trichomes in Solanaceae are known to have a key role in the detoxification of Cd, Ni, Pb and Zn. Expressed sequence tag (EST)-based large-scale gene analysis in tobacco has indicated that trichomes are biologically active and stress-responsive structures. Trichome secretions and exudates also play an active role in metal detoxification process. Given that trichomes provide chemical defense from heavy metal stresses in the form of sequestration and extrusion, the plants having trichomes have potential role in remediation of contaminated soils. Solanaceae trichomes can serve as important model tissues that can be modified to attenuate metal toxicity, serve as environmental indicators and enhance phytoremediation potential of the family.
