“…This enzyme catalyzes the dismutation of the superoxide anion into H 2 O 2 plus molecular oxygen [28]. Similar to CAT, we found that SOD activity was increasing in bean seeds as higher Fe dose were used (25 and 50 µM), with the two forms of Fe used.…”

The aim of this study was to evaluate the effect of iron biofortification on antioxidant response, yield and nutritional qualityof green bean (Phaseolus vulgaris L.) under greenhouse conditions. Fe was applied using two forms (FeSO 4 and Fe-EDDHA) at four doses of application (0, 25, 50 and 100 µm) added under a hydroponic system, and were tested over a period of 40 days. The Fe content was assessed in seeds, as well as the activity of antioxidant enzymes, production of H 2 O 2 , yield and nutritional quality. The results being obtained indicated that the accumulation of Fe in bean seeds enhanced with the application of Fe-EDDHA at the dose of 25 µm. This demonstrated that low Fe application dose was enough to increase Fe levels in seeds of common bean. In addition, Fe-EDDHA application form at 50 µmol was the best treatment to improve crop yield. Respect to antioxidant system, chelated form of Fe (Fe-EDDHA) was more effective in the activation of antioxidant enzymes (CAT, SOD and GSH-PX), and a lower content of H2O2 in green bean seeds. Finally, to raise the Fe concentration in bean under biofortification program was a promising strategy in cropping systems in order to increase the ingestion of iron and antioxidant capacity in the general population and provided the benefits that this element offered in human health.

“…Based on the occurrence of the highest activities, we can speculate that in 0.5 h after herbivory damage a rapid burst of H 2 O 2 occurs, and then the activities of these enzymes gradually increase leading to a gradual decrease in H 2 O 2 level. It has been reported that mechanical damage induces a rapid accumulation of H 2 O 2 in short term (about 5 min after wounding) in Mesembryanthemum crystallinum leaves, which reaches the highest content at 15 min and then begin to decrease at 20 min (Slesak et al 2008). Moreover the high level of H 2 O 2 is accompanied by a decrease in CAT activity, which reaches the lowest value at 15 min and then begins to increase at 20 min (Slesak et al 2008).…”

In response to Clostera anachoreta larvae attack, poplar (Populus simonii 9 P. pyramidalis 'Opera 8277') leaves produced a high level of hydrogen peroxide (H 2 O 2 ). Histochemical localization revealed that H 2 O 2 was mainly localized in herbivore-wounded zones and might spread through the veins. The activities of three H 2 O 2 -scavenging enzymes, i.e., peroxidase (POD), ascorbate peroxidase (APX), and catalase (CAT), were also enhanced in herbivore-wounded leaves, and exhibited an opposite pattern to the accumulation of H 2 O 2 . It was found that diphenylene iodonium chloride (DPI, a special inhibitor of NADPH oxidase) treatment significantly inhibited the accumulation of H 2 O 2 induced by herbivory damage. Moreover, DPI treatment led to an obvious decrease in the activities of POD, APX, and CAT. The results indicated that NADPH oxidase contributed to the accumulation of H 2 O 2 and the increase in activities of H 2 O 2 -scavenging enzymes in poplar leaves induced by herbivory damage. The balance between H 2 O 2 -production pathway and H 2 O 2 -scavenging enzymes led to the tolerable level of H 2 O 2 acting in P. simonii 9 P. pyramidalis 'Opera 8277' cuttings in response to herbivory damage.

“…It is supposed that in such a defense metal ion may kill or inhibit the growth and development of plant pests, cause deterrence, save energydemanding organic defenses, or sometimes confer a rarely complete, pathogen resistance [28]. Caused by herbivory, biotic stress is known to be accompanied by a formation of a large quantity of hydrogen peroxide [32], which decomposition in living organisms is achieved by Se-dependent [37] glutathione peroxidase [1]. The phenomenon of anomalous Se accumulation by leaves of genetically modified potato resistant to Colorado potato beetle (Leptinotarsa decemlineata, Coleoptera) may be considered as an indirect evidence of the protective Se effect against beetle pests [33].…”

Selenium is an essential trace element for animal and human beings. Despite the importance of insects in most ecosystems and their significant contribution to the biological cycling of trace elements due to high abundance, population productivity, and diverse ecosystem functions, surprisingly little information is available on selenium bioaccumulation by these arthropods. This review considers selenium essentiality and toxicity to insects as well as insects' contribution to selenium trophic transfer through the food chains. Data on Se accumulation by insects of the Dniester River Valley with no anthropogenic Se loading reveal typically low Se content in necrophagous insects compared to predators and herbivores and seasonal variations in Se accumulation.
