“…In this context, the experimental areas in each potato fields were selected ( Figure 1 ) to minimize the effects of runoff water [ 38 ]. As soil is the primary source for potato plants to receive mineral elements through their roots [ 7 , 12 ], in all these fields the slightly basic pH of the soils was considered, since its acidification is frequently associated with deficiency of essential plant cations like Ca in potato crops [ 39 ]. Also, as Ca is the third most available nutrient in soils [ 40 ], being an essential nutrient for plants in the form of Ca 2+ [ 15 ], the positive correlation between exchangeable Ca and soil organic carbon in the soil (i.e., an increase in soil organic carbon concentration generally increases the cation exchange capacity) must be considered [ 41 ] for potato production.…”

“…Nonetheless, agronomic biofortification, a fast, reliable, sustainable, accessible, and cost-effective way to increase minerals content [ 8 , 9 , 10 , 11 ], can surpass Ca deficiency, allowing its enrichment in the edible parts of selected food crops. In fact, selection of basic crops for biofortification, consumed worldwide, can improve low-quality diets, where there is a limited choice of foods and the soils are devoid of bioavailable nutrients [ 10 , 12 ], affecting the uptake and translocation of minerals to the edible portions [ 7 , 13 ].…”

This study aimed to assess the efficiency of Ca enrichment in tubers of three genotypes of Solanum tuberosum L., through foliar spraying with CaCl2 and Ca(NO3)2 solutions. In this context, soil heterogeneity of three potato-growing fields, as well as the implications of Ca accumulation among tissues and some quality parameters were assessed. Three potato varieties (Agria, Picasso and Rossi) were grown in three production fields and during the life cycle, four pulverizations with calcium chloride (3 and 6 kg ha−1) or calcium nitrate (0.5, 2 and 4 kg ha−1) were applied. For screening the potential phytotoxicity, using Agria as a test system, the potential synthesis of photoassimilates was determined, and it was found that after the 3rd Ca application, leaf gas exchanges were moderately (net photosynthesis), to strongly (stomatal conductance) affected, although without impact on Ca accumulation in tubers. At harvest, the average Ca biofortification index varied between 5–40%, 40–35% and 4.3–13% in Agria, Picasso and Rossi, respectively. Moreover, the equatorial region of the tubers in general showed that Ca accumulation prevailed in the epidermis and, in some cases, in inner areas of the potato tubers. Biofortified tubers with Ca also showed some significant changes in total soluble solids and colorimetric parameters. It is concluded that Ca enrichment of potato tubers through foliar spraying complemented the xylem mass flow of Ca from roots, through phloem redistribution. Both fertilizers showed similar efficiency, but Rossi revealed a lower index of Ca accumulation, eventually due to different metabolic characteristics. Although affected by Ca enrichment, potato tubers maintained a high quality for industrial processing.

“…The biofortification process is a method in which selected nutrients (e.g., Ca, Cu, Fe, I, Se, and Zn) or nutritional materials are inserted into the food chain [94]. These materials might include folate [95][96][97], riboflavin [98,99], lysine [100][101][102], and pro-vitamin A [103].…”

Selenium and Nano-Selenium Biofortification for Human Health: Opportunities and Challenges

et al. 2020

Selenium is an essential micronutrient required for the health of humans and lower plants, but its importance for higher plants is still being investigated. The biological functions of Se related to human health revolve around its presence in 25 known selenoproteins (e.g., selenocysteine or the 21st amino acid). Humans may receive their required Se through plant uptake of soil Se, foods enriched in Se, or Se dietary supplements. Selenium nanoparticles (Se-NPs) have been applied to biofortified foods and feeds. Due to low toxicity and high efficiency, Se-NPs are used in applications such as cancer therapy and nano-medicines. Selenium and nano-selenium may be able to support and enhance the productivity of cultivated plants and animals under stressful conditions because they are antimicrobial and anti-carcinogenic agents, with antioxidant capacity and immune-modulatory efficacy. Thus, nano-selenium could be inserted in the feeds of fish and livestock to improvise stress resilience and productivity. This review offers new insights in Se and Se-NPs biofortification for edible plants and farm animals under stressful environments. Further, extensive research on Se-NPs is required to identify possible adverse effects on humans and their cytotoxicity.

“…Given that Se addition forms a methionine and converts to Se-Met that accumulates as organic Se in plant tissues, high doses may reduce free methionine levels -an important substrate of ethylene biosynthesis -and finally decrease ethylene production (Hachmann et al, 2019;Oliveira et al, 2019). Because lycopene is responsible for tomato fruit color characteristics and one of the main antioxidants consumed by humans in a regular diet, it is also an important visual characteristic for consumers.…”

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.
