“…5). Similar results were found in Cd stressed (Cao et al, 2014b) and salt/drought-stressed barley (Ahmed et al, 2013), Cd stressed maize (Li et al, 2016). Exogenous Se mitigated these Cd-induced increased in ATPase activities, which indicated that Se ameliorated Cd toxicity by modulating ATPase activity.…”

In the present study, the role of selenium in cadmium toxicity was investigated in cucumber seedlings by hydroponic experiments. The application of Se for cucumber exposed to Cd significantly reduced Cd accumulation in all tissues, elevated Cd-depressed chlorophyll content, and improved photosynthetic performance. External Se significantly reduced ·OH, H 2 O 2 and malondialdehyde content. Exogenous Se balanced Cd-depressed elements (e.g., Se enhanced Cd-induced decreases in root Zn, leaf/stem/root Mn concentrations) and carbohydrate contents. External Se also significantly decreased the Cd-induced increases in Na + K + -, Ca 2+ Mg 2+ -and total ATPase activities, which recovered almost to control level. Results indicate that application of Se can alleviate Cd toxicity in cucumber seedlings by reducing Cd uptake and reactive oxygen species (ROS) accumulation, moreover protecting photosynthetic machinery from damaging, balancing elements and carbohydrate contents, and improving ATPase activities in cucumber.Additional key words: alleviating effects; photosynthetic performance; ATPase.

“…Cd translocation from soil to plant organs is an important factor in identifying specific cultivars and concentration level considered toxic for varying rice cultivars. Different cultivars showed differential response regarding Cd uptake and transport under heavy metal stress conditions; however their response does vary based on concentration and cultivar genotypic storage and translocation potential [14]. Furthermore, the tolerance and sensitivity indices of a specific rice cultivar are related to root Cd storage ability and its speciation in above-ground plant parts.…”

Cadmium (Cd) toxicity has varying consequences on plants growth and development. This research focused on examining the influence of Cd toxicity on fragrant rice genotypes and its consequences on yield, yield related parameters, and grain quality traits. Randomized complete block design comprising five different fragrant rice cultivars (Meixiangzhan 2, Xiangyaxiangzhan, Guixiangzhan, Basmati, and Nongxiang 18) and four Cd levels (0, 50, 100, and 150 mg/kg soil) was used. The results showed that, with increased levels of soil Cd toxicity, Cd uptake in roots and distribution to other organs increased in dose dependent manner. Uptake and accumulation were higher in roots than in shoots with the highest uptake in both roots and shoots observed in Meixiangzhan 2, followed by Nongxiang 18, Basmati, Xiangyaxiangzhan, and Guixiangzhan cultivars. With increased Cd toxicity, yield and yield parameters were affected in all cultivars. Grain quality was also found affected under Cd stress condition. The results suggested that soil Cd toxicity has negative consequences on rice performance and uptake varies among cultivars. Conclusively, Cd toxicity impaired rice yield formation and grain quality by altering yield components (panicles number, spikelet per panicles, and spikelet setting (%)); however, Guixiangzhan variety performed better, while Meixiangzhan 2 performed less in terms of minimum Cd uptake and distribution to grains, yield, and grain quality reduction under Cd stress condition.

“…Most As and Cd intake by humans originates directly or indirectly from contaminated crops. High concentrations of As and Cd in the edible part of plants have been reported in crops grown in contaminated soils [2][3][4], and chronic consumption of contaminated crops results in potentially human health risks. Evidence indicates that people consuming Cd-contaminated rice have developed " itai-itai disease" [5].…”
