“…Flax is an appropriate species to examine because it accumulates Cd within its seeds and is a prominent food source for linoleic and linolenic acids. Moreover, flax plants can survive on Cd‐containing soils with minimal effects on above‐ and below‐ground growth . In our previous research with flax, we found that mycorrhizal fungi counteracted the negative effects of below‐ground Cd on seed production but enhanced the concentration of Cd within seeds .…”

“…Flax plants also produce secoisolariciresinol diglucoside, a lignan that can chelate heavy metals [ 15 ]. Flax has been shown to tolerate cadmium and is suitable for the phytoremediation of contaminated soils [ 16 , 17 , 18 ]. Flax does not accumulate cadmium in ranges of 10,000 mg Cd 2+ kg −1 like the cadmium hyperaccumulator species (e.g., Thlaspi spp.…”

Cadmium is one of the most toxic heavy metal pollutants, and its accumulation in the soil is harmful to agriculture. Plants have a higher cadmium tolerance than animals, and some species can be used for phytoremediation. Flax (Linum usitatissimum L.) can accumulate high amounts of cadmium, but the molecular mechanism behind its tolerance is unknown. Here, we employed four genotypes representing two fiber cultivars, an oilseed breeding line, and a transgenic line overexpressing the metallothionein domain for improved cadmium tolerance. We analyzed the proteome of suspensions and the proteome and metabolome of seedling roots in response to cadmium. We identified more than 1400 differentially abundant proteins representing putative mechanisms in cadmium tolerance, including metal-binding proteins and transporters, enzymes of flavonoid, jasmonate, polyamine, glutathione metabolism, and HSP70 proteins. Our data indicated the role of the phytohormone cytokinin in the observed responses. The metabolome profiling found that pipecolinic acid could be a part of the cadmium accumulation mechanism, and the observed accumulation of putrescine, coumaric acid, cinnamic acid, and coutaric acid confirmed the role of polyamines and flavonoids in tolerance to cadmium. In conclusion, our data provide new insight into cadmium tolerance and prospective targets for improving cadmium tolerance in other plants.

“…In developing country like India, it is difficult to convince environmental regulators and local agencies to grow metal accumulators (the data on hyperaccumulators is scanty) in the contaminated areas for the sole purpose of removing pollutants from their environment unless financial renumeration or expenses are subsidized.

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.
