“…As already mentioned, while an increase in the abundance of proteins involved in glycolysis, pentose phosphate pathway, and oxidative stress defence is usually recorded in response to Cd and Zn treatment (Yuan et al . ; Villiers et al . ), such an up‐regulation of proteins involved in C‐metabolism as observed in Z. fabago leaves is rarely recorded in other species, even at short‐term metal exposure and/or mild stress.…”

“…At this stage of development, Z. fabago may favour sugar synthesis rather than sugar mobilization through starch conversion as observed by Kieffer et al (2008) in poplar exposed to Cd treatment. As already mentioned, while an increase in the abundance of proteins involved in glycolysis, pentose phosphate pathway, and oxidative stress defence is usually recorded in response to Cd and Zn treatment (Yuan et al 2009;Villiers et al 2011), such an up-regulation of proteins involved in C-metabolism as observed in Z. fabago leaves is rarely recorded in other species, even at short-term metal exposure and/or mild stress. To the best of our knowledge, such an increase in proteins involved in photosynthesis was only reported in a high Cd-accumulating soybean cultivar and in Arabidopsis thaliana in response to short-term exposure to 10 and 100 μm Cd, respectively (Semane et al 2010;Hossain et al 2012).…”

“…To overcome these toxic effects, an up-regulation of enzymes involved in reactive oxygen species (ROS) detoxification have been evidenced, as well as proteins involved in protein folding and stabilization, and proteins which catalyse the conjugation of toxic elements with metabolites (Sarry et al 2006;Semane et al 2010;Hossain et al 2012). However, proteomic studies related to the impact of Zn excess remain scarce (Farinati et al 2009;Garcia et al 2009;Yuan et al 2009;Fukao et al 2011;Zeng et al 2011).…”

Cadmium and zinc share many similar physiochemical properties, but their compartmentation, complexation and impact on other mineral element distribution in plant tissues may drastically differ. In this study, we address the impact of 10 μM Cd or 50 μM Zn treatments on ion distribution in leaves of a metallicolous population of the non-hyperaccumulating species Zygophyllum fabago at tissue and cell level, and the consequences on the plant response through a combined physiological, proteomic and metabolite approach. Microproton-induced X-ray emission and laser ablation inductively coupled mass spectrometry analyses indicated hot spots of Cd concentrations in the vicinity of vascular bundles in response to Cd treatment, essentially bound to S-containing compounds as revealed by extended X-ray absorption fine structure and non-protein thiol compounds analyses. A preferential accumulation of Zn occurred in vascular bundle and spongy mesophyll in response to Zn treatment, and was mainly bound to O/N-ligands. Leaf proteomics and physiological status evidenced a protection of photosynthetically active tissues and the maintenance of cell turgor through specific distribution and complexation of toxic ions, reallocation of some essential elements, synthesis of proteins involved in photosynthetic apparatus or C-metabolism, and metabolite synthesis with some specificities regarding the considered heavy metal treatment.

“…Zou et al (2012) also reported that aquatic A. philoxeroides showed higher amount of peroxidase, which provides a greater resistance to adverse conditions in aquatic ecosystems. Peroxidase activity in aquatic plants was considered to be a critical determinant of tolerance to water pollution caused by pulp and paper mill effluents (Roy et al 1992), other industrial effluents (Nayek et al 2010) and also to heavy metals (Naqvi and Rizvi 2000), like copper (Xu et al 2011a), zinc (Yuan et al 2009) and cadmium (Ding et al 2007).…”

An attempt was made to understand the potential of Alternanthera philoxeroides, alligator weed to adapt to diverse conditions present in pond ecosystems, through a correlative investigation of its natural growth pattern and peroxidase level. Eleven ponds were graded into two subjective categories: "A. philoxeroides Infestation" (High, Medium, Low) and "Level of Pollution" (High and Low), to test for difference in mean peroxidase concentration in A. philoxeroides populations. Significant changes in mean peroxidase concentration in A. philoxeroides were found in ponds categorized on the basis of level of pollution, indicating the adaptability of this plant to propagate under pollution stress. On the other hand, there was no significant change in mean peroxidase concentration for plants growing in ponds categorized on the basis of infestation showed that dense, vegetative proliferation caused no stress in A. philoxeroides. An efficient method of assaying peroxidase in A. philoxeroides, under field conditions, using the best suited leaf group (Tips, Tips + 1st leaf pair", 2nd leaf pair) was also explored. "Tips + 1st leaf pair" proved to be a better sample than mature leaves for estimation of peroxidase concentration in A. philoxeroides.

Environmental decontamination is an integral part of sustainable development. In recent years there has been growing interest in using plants for decontamination. On the other hand, water, soil and air are increasingly contaminated. Large amounts of toxic waste have been dispersed in thousands of contaminated sites spread all over the globe. These pollutants belong to two main classes: inorganic and organic. The challenge is to develop innovative and costeffective solutions to decontaminate polluted environment. Phytoremediation is emerging as an invaluable tool for environmental cleanup. Various strategies are being applied to reduce the accumulation of toxic metals in plants. Cultivation of edible crops in contaminated soils is a subject of human health concern if the contaminant concentration in the edible parts of crops plant exceed the permissible level. In such cases non-food crop production viz. value chain and value additions appears profitable. In this review: (1) the contamination due to industrial effluents in peri urban region of greater Hyderabad, and (2) the strategies to use contaminated soil and water for raising phytoremediation crops, and generation of value products. Crops and products include medicinal and aromatic plants, ornamental plants, biofuels, tree crops, fiber crops, dyes, and plants for carbon sequestration.
