“…These results are in accordance with the earlier reports demonstrate that, SA-induced protective response to DNA damaging agents (Bautz &Freese, 1960 andPatra et al, 2005). Earlier results also suggested that SA treatment led to a decrease in oxidative injuries induced by Cd Patra, 2007). The production of H 2 O 2 during abiotic stress serves as part of the signaling cascade, and increased levels of ROS might interact with SA.…”

C ADMIUM (Cd) is a toxic heavy-metal pollutant in the environment, it is a nonessential element, which strongly inhibits plant growth and development, and causes plant death even at very low concentrations. Root tip cells of Nigella sativa were separately treated with different concentrations (5, 10, 25 and 50ppm) of cadmium for 3, 6, 12 and 24h and the results were recorded. The results showed that all concentrations of cadmium reduced the mitotic index and caused a disturbance in the frequencies of mitotic phases. The treatment with 50ppm of metal for 24h was the most effective in reducing the mitotic activity and inducing the highest percentage of mitotic abnormalities. The different types of abnormalities were irregulatries, bridges, sickness at different phases, disturbed chromosomes or bi nucleated cells, forward and lagging chromosomes. Also, in this study three concentrations of SA (0.01, 0.1 and 0.2mM) for 6 and 12h were used to recover the cytotoxicity of the cadmium treatment (50ppm for 3 and 24h). This Post treatment with SA resulted in increasing MI and significant reduction of chromosomal abnormalities. These results illustrate the ameliorating effect of SA under stress conditions and reveal that SA is effective in alleviating the toxic effects of heavy metals at all applied concentrations.

“…This may lead to an increase in the uptake and retention of water that aids in maintenance of higher RWC content and osmotic balance resulting in improved growth under Al stress. Similar results of reduced uptake of Al and Cd by salicylic acid were reported in rice, Cassia tora and maize [23] [24]. In plant growth experiments, the improved plant growth noticed with SA supplementation explains the role of SA to enhance auxin mediated root elongation.…”

The aim of this work was to evaluate the alleviating efficacy of salicylic acid (100, 250 and 500 μM) against the toxic effects of aluminum (Al) on two tomato cultivars (GOWRI and SIRI) differing in their sensitivity to Al stress. Al treatment (500 µM) caused 40% -80% drop in plant growth, relative water content (RWC) and cell viability and a reduction of 1 -2.5 fold and 0.5 -2 fold in glutathione and proline content respectively, when compared to their control plants grown in Al free medium. Al treatment also resulted in 2 -5 fold raise in malondialdehyde (MDA) levels, 2 -3 fold higher Al uptake and 55% -80% more electrolyte leakage and caused severe DNA damage. Al stress enhanced (1 -2 fold) the activities of superoxide dismutase (SOD) and peroxidase (POD), but decreased catalase (CAT) activity over their respective controls. Exogenously-applied Salicylic acid (SA) significantly (p < 0.05) and dose-dependently alleviated Al-induced toxicity in tomato seedlings as marked by much improved plant growth, retention of higher RWC, cell viability, glutathione and proline content. SA also caused 0.6 -1.5 fold reduction in Al uptake, 50% -80% less electrolyte leakage, 40% -80% drop in lipid peroxidation and considerable protection against DNA damage. Also, supplementation of SA could considerably reverse the Al-induced changes in the activities of SOD, POD and CAT. Together, our findings demonstrate that, SA is an efficient growth regulator with diversified roles that contribute to its potential alleviating effect against Al induced toxicity and SIRI is a relatively Al-resistant cultivar compared to GOWRI. * Corresponding author.

“…As previously documented, the exogenous application of salicylic acid to rice (Choudhury and Panda 2004;Panda and Patra 2007) or mustard (Ahmad et al 2011) seeds significantly lowered Cd accumulation and reduced metal toxicity. Similar results were reported by Belkadhi et al (2012) for flax seedlings.…”

Common reed (Phragmites australis (Cav.) Trin. ex Steud.) plants were harvested from four natural water ecosystems of the Bogdanka river catchment (Poznań, Poland) four times throughout the 2014 vegetative season. Over the year, average metal contents followed different decreasing trends according to the analyzed tissue: (leaves), and mean translocation ratios (leaves/rhizomes) were found as follows: 0.93, 0.70, 0.65, 0.40 for Zn, Pb, Cd and Cu, respectively. Metal content increased gradually during the growing season, and in the case of Cu, Cd and Pb exceeded the upper limit of average concentration detected in plants from natural ecosystems. However, the content of salicylic acid did not follow the increase of metal accumulation. In rhizomes, the highest production of the metabolite was observed in May and reached 324 ng g -1 fresh weight (FW) (mean value). Afterwards, a significant drop to 50 ng g -1 FW was observed. Simultaneously, the highest values of total salicylic acid in P. australis leaves were observed in July and accompanied the intensive development of the aboveground biomass of the plant (11.3 lg g -1 FW-mean value). Subsequently, its content in leaves showed a significant decrease down to 2.1 lg g -1 FW in November. Multivariate regression analysis revealed significant interactions between analyzed metals influencing the plant response to metal-derived stress. Cu and Zn showed antagonistic properties considering their uptake and the induction of salicylic acid biosynthesis, whereas non-essential metals (Pb and Cd) acted similarly and stimulated the formation of salicylic acid glucoside.
