“…Presumably, the constant exposure of the plant root system to the Se-enriched solution and the lack of Se-soil interactions acted jointly to make soilless cultivations particularly efficient (Ryant et al, 2020). The smallest Se dose may satisfy the daily consumption requirements of this element (55-200 mg/day per adult) proposed by WHO (Stefani et al, 2020).…”

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.

“…In case of grapes, the accumulated heavy metals such as Pb, Cr, Cd, As, and Ni showed a significant reduction after foliar spraying with Se fertilizers (Zhu et al, 2017). Se content in fruits even improves the fruit flavor and quality (Ryant et al, 2020). Se has been observed to reduce the biosynthesis of ethylene, the hormone responsible for plant senescence and fruit ripening.…”

“…Further, Se has been observed to induce a partial stomatal closure, as revealed by the values of stomatal conductance that results in reduction in the net assimilation, thereby decreasing dry‐matter production (Ryant et al, 2020). Amino acid–chelated Se is known for its impact on pear, grape, and peach for enhancing net photosynthetic rate and decreased stomatal conductance and transpiration rate (Feng et al, 2013).…”

Selenium (Se) is a vital mineral for both plants and animals. It is widely distributed on the earth's crust and is taken up by the plants as selenite or selenate. Plants substantially vary in their physiological response to Se. The amount of Se in edible plants is genetically controlled. Its availability can be determined by measuring its phytoavailability in soil. The low concentration of Se in plants can help them in combating stress, whereas higher concentrations can be detrimental to plant health and in most cases it is toxic. Thus, solving the double‐edged sword problem of nutritional Se deficiency and its elevated concentrations in environment requires a better understanding of Se uptake and metabolism in plants. The studies on Se uptake and metabolism can help in genetic biofortification of Se in plants and also assist in phytoremediation. Moreover, Se uptake and transport, especially biochemical pathways of assimilation and incorporation into proteins, offers striking mechanisms of toxicity and tolerance. These developments have led to a revival of Se research in higher plants with significant break throughs being made in the previous years. This review explores the new dimensions of Se research with major emphasis on key research events related to Se undertaken in last few years. Further, we also discussed future possibilities in Se research for crop improvement.
