“…Investigations on Indian mustard cultivars with different degrees of Cd tolerance showed that higher tolerance was due to better coordination between the antioxidant enzymes [28]. Although similar basal antioxidant enzyme activities were detected, Cd stress induced different changes in tolerant and sensitive cell lines of cucumber [29]. In the present work it was found that the initial antioxidant enzyme activities did not differ pronouncedly in the four wheat genotypes.…”

Wheat genotypes with different endogenous SA contents were investigated, in order to reveal how cadmium influences salicylic acid (SA) synthesis, and to find possible relationships between SA and certain protective compounds (members of the antioxidants and the heavy metal detoxification system) and between the SA content and the level of cadmium tolerance.Cadmium exposure induced SA synthesis, especially in the leaves, and it is suggested that the phenyl-propanoid synthesis pathway is responsible for the accumulation of SA observed after cadmium stress. Cadmium influenced the synthesis and activation of protective compounds to varying extents in wheat genotypes with different levels of tolerance; the roots and leaves also responded differently to cadmium stress. Although a direct relationship was not found between the initial SA levels and the degree of cadmium tolerance, the results suggest that the increase in the root SA level during cadmium stress in the Mv varieties could be related with the enhancement of the internal glutathione cycle, thus inducing the antioxidant and metal detoxification systems, which promote Cd stress tolerance in wheat seedlings. The positive correlation between certain SA-related compounds and protective compounds suggests that SA-related signalling may also play a role in the acclimation to heavy metal stress.

“…53-60) observed a significant decrease in SOD activity and its loss in shoot and root of wheat under the stress of Cd and Cu. The effects of heavy metals such as Cd and Cu on antioxidant enzymatic activities such as SOD and POD have been previously observed in cucumber [51], rice, [52], pea plants [53], Kandelia candel and Bruguiera gymnorrhiza [18]. At higher concentration of Pb, the SOD decreased significantly in water hyacinth [45].…”

“…According to Wang et al [4] (pp. [48][49][50][51][52][53][54], the root growth of cucumber, tomato, lettuce, and carrot increased in the presence of nano-Fe 3 O 4 and other nanoparticles compared with control (Cd, EC 50 ). These results suggested that nano-Fe 3 O 4 can alleviate the toxicity of the selected heavy metals in the growth of plants.…”

Heavy metal pollution is not only a hazard to living organisms but also an important worldwide environmental concern. Experiments were performed to investigate the physiological mechanisms of magnetic (Fe 3 O 4 ) nanoparticles (nano-Fe 3 O 4 ) mitigation of the toxicity of heavy metals (Pb, Zn, Cd and Cu) in wheat seedlings. All the Petri dishes with germinating seedlings (1d) were covered, sealed with parafilm, and placed in a dark growth chamber. All parameters (seedling growth inhibition, heavy metal accumulation, enzymatic activities, and reducing effects of nano-Fe 3 O 4 on heavy metal toxicity) were analyzed only after five days. The results showed that the tested heavy metals significantly affected the growth of wheat seedling by decreasing root length, shoot length and even death at 10 mM concentration in the case of Cd and Cu. Heavy metals exposure also showed that superoxide dismutase (SOD) and peroxidases (POD) activities decreased significantly when the malondialdehyde (MDA) content was significantly higher in wheat seedlings. Addition of magnetic (Fe 3 O 4 ) nanoparticles (2000 mg/L) in each heavy metal solution (1 mM) significantly decreased the growth inhibition and activated protective mechanisms to reduce oxidative stress induced by heavy metals in the wheat seedlings. The reducing effects of nano-Fe 3 O 4 against heavy metals stress could be dependent on the increase in the enzyme activity (SOD and POD). Their protective role was confirmed by the decrease in MDA content. The alleviating effect of nano-Fe 3 O 4 is associated with their adsorption capacity of heavy metals.
