“…Belkadhi et al reported that the Cd-treated plantlets presoaked with SA exhibited less lipid and protein oxidation and membrane alteration, as well as a high level of total antioxidant capacities and increased activities of antioxidant enzymes except of CAT. They suggested that SA plays an important role in triggering the root antioxidant system, thereby preventing membrane damage as well as the denaturation of its components [57]. In this study, we found that in SA-treated plants, POD activity was increased in all treatment groups but CAT activity was decreased on the 10 th day (Tables 1 and 4).…”

“…Belkadhi et al (2013) showed that exogenous SA protected membranes against a loss of integrity and lipid peroxidation by increasing fatty acid unsaturation in Linum usitatissimum roots. Later, Belkadhi et al 2015 further reported that exogenous SA also protected phospholipids of L. usitatissimum by decreasing the percentages of monogalactosyldiacylglycerol, phosphatidylcholine, phosphatidylethanolamine and phosphatidylglycerol.…”

This review summarizes the findings of the most recent studies, published from 2000 to 2016, which focus on the biogeochemical behavior of Cd in soil-plant systems and its impact on the ecosystem. For animals and people not subjected to a Cd-contaminated environment, consumption of Cd contaminated food (vegetables, cereals, pulses and legumes) is the main source of Cd exposure. As Cd does not have any known biological function, and can further cause serious deleterious effects both in plants and mammalian consumers, cycling of Cd within the soil-plant system is of high global relevance.The main source of Cd in soil is that which originates as emissions from various industrial processes. Within soil, Cd occurs in various chemical forms which differ greatly with respect to their lability and phytoavailability. Cadmium has a high phytoaccumulation index because of its low adsorption coefficient and high soil-plant mobility and thereby may enter the food chain. Plant uptake of Cd is believed to occur mainly via roots by specific and non-specific transporters of essential nutrients, as no Cd-specific transporter has yet been identified. Within plants, Cd causes phytotoxicity by decreasing nutrient uptake, inhibiting photosynthesis, plant growth and respiration, inducing lipid peroxidation and altering the antioxidant system and functioning of membranes. Plants tackle Cd toxicity via different defense strategies such as decreased Cd uptake or sequestration into vacuoles. In addition, various antioxidants combat Cd-induced overproduction of ROS. Other mechanisms involve the induction of phytochelatins, glutathione and salicylic acid.

“…It has been reported that exogenous SA treatment may ameliorate the damaging effects of heavy metals in many plants (Agami and Mohamed 2013;Dražic and Mihailovic 2005;Krantev et al 2008;Metwally et al 2003;Popova et al 2009). SA-induced Cd tolerance in plants is attributable to its enhancement of antioxidant defense activities and regulation of Cd uptake, transport, and distribution in plant organs (Belkadhi et al 2013;Guo et al 2009;Wang et al 2011).…”

Cadmium (Cd) toxictity and possible role of salicylic acid (SA) in alleviating Cd-induced toxicity were investigated on ornamental hydrophyte Iris hexagona. Compared to the control, treatments with 100 and 500 µM Cd for 7 days significantly decreased dry weight, the contents of chlorophyll, photosynthetic parameters, and increased the content of thiobarbituric acid reactive substance. Pretreatment of the roots of I. hexagona seedlings with 1 µM SA before Cd exposure may increase dry weight, photosynthetic rate, activities of antioxidant enzymes, improve the cell ultrastructure and protect plants from Cd-induced oxidative stress damage. However, SA pretreatment had no significant effect on Cd concentrations in the leaves and roots. It is suggested that SA-induced Cd tolerances in I. hexagona are likely associated with increases in antioxidant enzyme activities and vacuolar compartmentation, rather than Cd uptake.
