“…However, soil application with Se-rich solid fertilizer (37.5 g·ha −1 as the form of Se 4+ ) increased the growth of wheat, resulting in higher shoot dry weight and grain yield (Xia et al, 2020 ). (Wang et al, 2021 ) showed that regardless of the Se rate, the soil application of both Se 4+ and Se 6+ decreased the biomass and grain yield in almost all wheat cultivars, whereas Boldrin et al ( 2013 ) reported that the soil application of Se 4+ or Se 6+ had no effect on the growth of rice. De Vita et al ( 2017 ) showed that foliar application of Se 6+ had no effect on the growth of wheat, whereas Boldrin et al ( 2013 ) concluded that the soil application of Se 4+ or Se 6+ promotes the growth of rice.…”

“…Liu et al ( 2016a ) reported the Se accumulation ability in different maize organs descended in the order of root > leaf > grain > stem. Wang et al ( 2021 ) showed that the soil application of both Se 4+ and Se 6+ treatments increased the uptake of Se in each part of the wheat plant. Wheat is considered a non-accumulating cereal crop as it often shows approximately the same Se concentration in grains and roots and smaller amounts in the stem and leaves at the mature stage (Terry et al, 2000 ).…”

“…Thus, Se biofortification in wheat via agronomic approaches has been shown to be practical. It has been demonstrated that agronomic biofortification provides an effective approach to increasing Se concentration in wheat (Hawkesford and Zhao, 2007 ; Boldrin et al, 2018 ; Xia et al, 2020 ; Galic et al, 2021 ; Gupta et al, 2021 ; Wang et al, 2021 ). Se-enriched wheat grains can be used as a dietary source of Se to reduce the occurrence of Se deficiency-related health problems.…”

“…Soil and foliar applications via sodium selenite (Na 2 SeO 3 ) enhanced organic grain Se concentration within wheat (Xia et al, 2020 ). Both Na 2 SeO 4 and Na 2 SeO 3 soil application increased action on transporters, thereby affecting the accumulation of Se in wheat (Wang et al, 2021 ). Ziyang, located in the Daba Mountain area of Southern Shannxi Province, China, is a well-known Se-enriched area, with Se distribution in rocks ranging from 0.23 to 57.0 mg·kg −1 (Tian et al, 2016b ).…”

In Se-deficient populations, Selenium- (Se-) enriched wheat is a source of Se supplementation, and Se content can be improved by agronomic biofortification. Thus, black-grained wheat (BGW) and white-grained wheat (WGW) (as the control) were grown in Se naturally contained soils at different concentrations (11.02, 2.21, 2.02, and 0.20 mg·kg−1). Then, a field experiment was conducted to assess agronomic performance, the concentration of microelements and heavy metals, and the uptake and distribution of Se in the BGW under the application of Se ore powder. The results showed that the grain yield and grain Se concentration of wheat respectively show a significant increase and decrease from high Se to low Se areas. Higher grain yield and crude protein content were observed in Se-rich areas. The soil application of Se ore powder increased wheat grain yield and its components (biomass, harvest index, grain number, and 1,000 kernels weight). The concentrations of Zn, Fe, Mn, total Se, and organic Se in the grains of wheat were also increased, but Cu concentration was decreased. The concentrations of Pb, As, Hg, and Cr in wheat grains were below the China food regulation limits following the soil application of Se ore powder. Compared with the control, Se ore powder treatment increased the uptake of Se in various parts of wheat plants. More Se accumulation was observed in roots following Se ore powder application, with a smaller amount in grains. In addition, compared with the control, BGW had significantly higher concentrations of Zn, Fe, and Mn and accumulated more Se in grains and shoots and less Se in roots. The results indicate that wheat grown in Se-rich areas increases its grain yield and crude protein content. The soil application of Se ore powder promotes wheat growth and grain yield. Compared with WGW, BGW accumulated more Se in grains and had a higher concentration of organic Se in grains. In conclusion, the application of Se ore powder from Ziyang as Se-enriched fertilizer could be a promising strategy for Se biofortification in the case of wheat, and BGW is the most Se-rich potential genotype.

“…This approach has been explored as a practice for the enhancement of the Se content in edible plants, because there is a huge interspecies and intraspecies genetic variation in plants (Schiavon et al, 2020). Previous studies have demonstrated genetic variation in grain Se concentration of cereal crops, such as wheat (Sharma et al, 2016;Wang et al, 2021;White, 2016), rice (White, 2016;Zhang et al, 2006), oat and barley (White, 2016). Moreover, significant genetic variation effects on seed Se concentration of leguminous crops and edible parts of vegetables have also been observed.…”

Selenium (Se) is an essential trace element, playing a crucial role in the functioning of enzymes in humans and animals and protecting cells from damage by free radicals (Hatfield et al., 2014). Selenoproteins, that is, proteins containing selenium, are best known as antioxidants and catalysts for the production of active thyroid hormone (Rayman, 2012). Although the essential role of Se for the growth and survival of plants has not been confirmed yet, it is a beneficial element for plants, which can enhance resistance to stress (see Chapter 8).Despite the importance of this trace element, intake of Se by animals and humans in a wide range of countries, including several countries in Western Europe and East and Central Africa, is still low, resulting in Se deficiency and causing negative health effects, including increased risk of mortality, poor immune function, and cognitive decline (Broadley et al., 2006;Rayman, 2012;Roekens et al., 1986). An estimated one billion people around the world are affected by selenium deficiency, because of low Se intake (Poblaciones & Rengel, 2017;Rayman, 2004). The recommended daily Se intake in an adult human diet is 0.04-0.4 mg per person per day (Food and Agriculture Organization of the United Nations/World Health Organization [FAO/WHO], 2001). Besides, farm animals (Dermauw et al., 2013) and pets (van Zelst et al., 2016) can be affected by Se deficiencies, leading to economic losses. Therefore, the Se content in the human

BACKGROUND Selenium (Se) deficiency is a recognized problem that threatens the health of people worldwide, and wheat is grown worldwide and is one of the major sources of dietary Se. Since there are few studies that have investigated the changes in Se content and speciation of different varieties of Se‐enriched wheat from primary to deep processing, we studied four naturally Se‐enriched kinds of wheat and two Se‐fertilized kinds of wheat. RESULTS Glutenin‑ and albumin‐bound Se accounted for the highest proportion of protein‐bound Se in refined wheat flour (7.29 ± 0.19 to 10.82 ± 0.50% and 6.16 ± 0.34 to 8.45 ± 0.07%); water‐soluble polysaccharide‐bound Se accounted for the highest proportion of polysaccharide‐bound Se in refined wheat flour (12.02 ± 0.54 to 24.62 ± 1.87%). Coarse bran Se content was significantly higher than refined wheat flour (137.94 ± 7.80 to 174.55 ± 5.09% for unpeeled wheat, 147.27 ± 10.96 to 187.72 ± 17.70% for peeled wheat). The peeling and processing of wheat into flour had different effects on Se the content and speciation dependent on the particular wheat variety. Whole wheat flour enabled better retention of selenomethionine (101.64 ± 2.32 to 138.41 ± 2.84% for unpeeled wheat, 158.59 ± 13.72 to 250.20 ± 4.94% for peeled wheat). The cooking process had no significant effect on Se content, but Se species were possibly interconverted. CONCLUSION The organic Se content of different varieties of Se‐enriched wheat was different, but the milling and cooking process retained the total Se and Se speciation better, which could be used for daily Se supplementation for Se‐deficient people. © 2022 Society of Chemical Industry.
