“…The observed results are in agreement with the results reported from Estonia, where the foliar application of Se fertilizer on A. sativum led to an increase in the content of Se in the bulbs, with an increased dose of Se fertilizer [39]. Similar results were obtained in previously published studies conducted on onion, garlic and lettuce [37,40,41].…”

Allium species are known as a rich source of many compounds with potential healing effects. Biofortification is recognized as an effective agrotechnical measure for raising the level of biogenic elements—especially microelements in the edible parts of these species, so Allium can be considered as a ‘natural dietary supplement’. The aim of this research was to test the effects of foliar application of Se fertilizer (Na2SeO4) in different doses (control—0, 10, 20 and 30 g per ha) on the content of macro, microelements and secondary metabolites (SMs)—free phenolics, flavonoids and hydroxycinnamic acid derivatives in the edible parts, i.e., leaves of two selected Allium species in Serbia (A. odorum and A. schoenoprasum), which grew in open field conditions over the course of two growing seasons. The bioaccumulation factor (BAF), as an indicator of the ability of plants to accumulate biogenic elements, was also determined. Although with no full regularity, the dose of 10 g of Se per ha yielded the highest content for the most biogenic elements for both alliums in the first growing season, i.e., a dose of 20 g of Se per ha for A. schoenoprasum, and a dose of 30 g of Se per ha for A. odorum in the second growing season. The obtained results justified the Se-biofortification of different alliums. The BAF values indicated the ability of both Allium species to accumulate S, K and P in their leaves during both growing seasons. The accumulation of potentially toxic elements was not recorded for either species, emphasizing the safety of the produced plant material for human consumption. Additionally, Se-treated plants had higher SM contents compared to control plants. The growing season also showed an impact on SM content; i.e., in the second season, characterized as drought-stressed, the synthesis of SMs was significantly higher compared to that in the first season. Further research should be directed towards finding the appropriate dose of Se, expanded in the sense of conducting research in controlled conditions, as well as different ways of applying Se fertilizer. The idea of this study was also to popularize the examined Allium species, which are rarely grown in the territory of Serbia.

“…Moreover, Se is an essential constituent of selenoenzymes, some of which have antioxidant functions improving the nutraceutical quality of the edible part of the crop (Garduño-Zepeda et al, 2018;Silva et al, 2020) and reducing ROS production, such as, O2− and H2O2 (Thavarajah et al, 2017;D'Amato et al, 2018). However, Se in high concentrations acts as pro-oxidant causing oxidative stress in plants (Astaneh et al, 2018;Skrypnik et al, 2019), which is possibly related to an increase in enzymatic and non-enzymatic antioxidants (Pannico et al, 2019;Pérez et al, 2019). This result causes failure in the protein structure when non-specific cysteine and methionine in proteins are substituted by SeCys and SeMet in the plant (Chomchan et al, 2017;Garduño-Zepeda et al, 2018), which leads to replacing cysteine with SeCys protein preventing the formation of disulfide bridges.…”

Selenium (Se) is an essential element for humans. Its consumption comes from food of animal or vegetal origin; whose content varies widely depending on its availability in soil or anthropogenic sources. Biofortification improves food nutritional quality, and its consumption has a positive influence in human health. Thus, the objective of this research was to assess agricultural biofortification with Se in tomato fruit and its effects on yield, nutraceutical quality, and antioxidant capacity. Five Se doses (0, 2, 4, 6, and 8 mg L-1) in the form of sodium selenite (Na2SeO3) were added in a nutritional solution in a hydroponic system. The results obtained indicated that agricultural biofortification with Se applied in the nutritional solution improved yield, nutraceutical quality, and Se concentration in tomato fruit. The optimum Se dose that maximized yield and nutraceutical quality, as well as the recommended consumption concentration in tomato fruit in this study was 2 mg L-1 (Na2SeO4) because higher doses decreased yield and bioactive compound biosynthesis. Incorporating Se in the nutritional solution is an alternative to increase phytochemical compound biosynthesis in tomato fruit and yield with the possibility of improving public health with its consumption.

“…Differences in transport and distribution mechanisms between plant species could explain the differences between the studies. Se was mainly stored in the leaves of Se 6+ -treated plants and in the roots of Se 2− -treated plants (Perez et al 2019;Sun et al 2020). SeMet was reported to be metabolized in roots (Ogra et al 2013) but Se 6+ appears to be primarily metabolized in leaves (Sors et al 2005;Terry et al 2000).…”

Selenium (Se), an essential micronutrient for humans, is also a beneficial nutrient for growth and development of many plants. The aim of the present study was to determine whether low-dose Se application could increase plum growth and serotonin synthesis, as well as upregulate the glutathione redox cycle. Two-year-old plum trees were treated with Se 6+ (Na 2 SeO 4) and Se 2− (SeMet). Growth parameters, levels of serotonin synthesis precursors, compounds and enzymes of the glutathione (GSH) redox cycle, and the antioxidant capacity were analyzed. Results showed that plant height and stem diameter were increased by Se treatment. The leaf Se content was significantly increased; tryptophan was not affected by Se treatment, while the 5hydroxytryptophan content was significantly higher than control. Although serotonin levels were also increased, the effect was not significant, and no tryptamine was detected in our study. On the 30th day, the MDA content in Se 2− was highest followed by the control and Se 6+ treatment, and the activities of T-AOT and CAT were increased, while GST was reduced by Se treatment. The two forms of Se treatments increased the activity of GPX and GR, and the total content of GSH + glutathione disulfide (GSSG) at the end of treatment. Furthermore, the level of GSH and GSH/GSSG was instable changed. GSSG content was similar during the treatment time except on the 20 days. Conclusively, the pathway of plum serotonin was clear, both Se 6+ and Se 2− could influence the serotonin synthesis. Additionally, the GSH redox cycle was sensitive to the Se application. Moreover, Se 6+ performed better than Se 2− on leaf Se content, plant growth parameters, and antioxidant capacity.
