“…Cadmium is believed as one of the most important contaminant in the ecosphere. The main sources of Cd in environment are mining and smelting of Cd-containing ores, municipal wastes, pesticides, trace emissions, burning of fossil fuels and fertilizers [ 1 , 2 ]. In plants, the first organ to contact the toxic metal ions are roots, and therefore roots have greater contents of metal than aerial parts [ 2 ].…”

BackgroundCadmium (Cd) is well known as one of the most toxic metals affecting the environment and can severely restrict plant growth and development. In this study, Cd toxicities were studied in strawberry cv. Camarosa using pot experiment. Chlorophyll and malondialdehyde (MDA) contents, catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX) activities and mineral nutrient concentrations were investigated in both roots and leaves of strawberry plant after exposure Cd.ResultsCd content in both roots and leaves was increased with the application of increasing concentrations of Cd. We found higher Cd concentration in roots rather than in leaves. Chlorophyll a and b was decreased in leaves but MDA significantly increased under increased Cd concentration treatments in both roots and leaves. SOD and CAT activities was also increased with the increase Cd concentrations. K, Mn and Mg concentrations were found higher in leaves than roots under Cd stress. In general, increased Cd treatments increased K, Mg, Fe, Ca, Cu and Zn concentration in both roots and leaves. Excessive Cd treatments reduced chlorophyll contents, increased antioxidant enzyme activities and changes in plant nutrition concentrations in both roots and leaves.ConclusionThe results presented in this work suggested that Cd treatments have negative effect on chlorophyll content and nearly decreased 30% of plant growth in strawberry. Strawberry roots accumulated higher Cd than leaves. We found that MDA and antioxidant enzyme (CAT, SOD and APX) contents may have considered a good indicator in determining Cd tolerance in strawberry plant.

“…Soil contamination of Cd increases with the increase in natural as well as anthropogenic activities (Tran and Popova 2013). The main entry of Cd into the environment is through the release of effluents from metallurgical industries, burning of fossil fuels, use of phosphate fertilizers, atmospheric deposition and sewage sludge applications (Ozbek et al 2014). Use of effluent water for irrigation is one of the major sources for Cd accumulation in suburban areas (Yasmeen et al 2014).…”

Serratiasp.CP‐13 augments the growth of cadmium (Cd)‐stressedLinum usitatissimumL. by limited Cd uptake, enhanced nutrient acquisition and antioxidative potential

Aims The current study was aimed to evaluate the beneficial effects and bioremediation potential of a Cd‐tolerant bacterial strain, Serratia sp. CP‐13, on the physiological and biochemical functions of Linum usitatissimum L., under Cd stress. Methods and Results The bacterial strain was isolated from the wastewater collection point of Chakera, Faisalabad, Pakistan, as this place contains industrial wastewater of the Faisalabad region. The Serratia sp. CP‐13, identified through 16S rRNA gene sequence analysis, exhibited a significant phyto‐beneficial potential in terms of in vitro inorganic phosphate solubilization, indole‐3‐acetic acid production and 1‐aminocyclopropane‐1‐carboxylic acid deaminase activity. Effects of Serratia sp. CP‐13 inoculation on L. usitatissimum were evaluated by growing the plants in CdCl2 (0, 5 or 10 mg kg−1 dry soil)‐spiked soil. Without inoculation of Serratia sp. CP‐13, Cd stress significantly reduced the plant biomass as well as the quantity of proteins and photosynthetic pigments due to enhanced H2O2, malondialdehyde (MDA) contents and impaired nutrient homeostasis. Subsequently, Serratia sp. CP‐13 increased the plant fresh and dry biomass, plant antioxidation capacity, whereas it decreased the lipid peroxidation under Cd stress. In parallel, Serratia sp. inoculation assisted the Cd‐stressed plants to maintain an optimum level of nutrients (K, Ca, P, Mg, Fe and Mn). Conclusions The isolated bacterial strain (Serratia sp. CP‐13) when applied to Cd‐stressed L. usitatissimum inhibited the Cd uptake, reduced Cd‐induced lipid peroxidation, maintained the optimum level of nutrients and thereby, enhanced L. usitatissimum growth. The analysis of bio‐concentration and translocation factor revealed that L. usitatissimum with Serratia sp. CP‐13 inoculation sequestered Cd in plant rhizospheric zone. Significance and Impact of the Study Serratia sp. CP‐13 inoculation is a potential candidate for the development of low Cd‐accumulating linseed and could be used for phytostabilization of Cd‐contaminated rhizosphere/soil colloids.

“…The main advantages of phytoremediation over other breeding methods include cheapness and not requiring any special equipment. The disadvantages include slow and variable remediation efficiency depending on the plant species used (Paz-Alberto and Sigua, 2013;Ozbek et al, 2014).…”

Introduction Mustard is among the oldest known spices, dating back to about 3000 BC (Mehra, 1968) and are cultivated for different edible and industrial uses especially in the spice and energy sector. Turkish natural flora of Sinapis alba syn. Brassica alba (white mustard or yellow mustard), S. arvensis syn. B. arvensis (wild mustard), B. juncea (brown mustard), B. rapa syn. B. campestris (field mustard or turnip), and B. nigra (black mustard) species are the most important among them (Babac, 2004; Guner et al., 2012; http://194.27.225.161/yasin/tubives/index.php?say fa=dizin&&familya=Acanthaceae) and will be discussed in the review explicitly. These species also contain other compounds like glycosides, arachidic acid, sinabine, lignoceric acid etc. in their oils. Abundance of erucic acid in these oils make them unsuitable for culinary purposes (Kires and Hammann, 2014). Previous studies show that mustard flora of Turkey has significantly high percentage (25%-35%) of seed oil (
