Selenium (Se) supplementation can restrict metal uptake by roots and translocation to shoots, which is one of the vital stress tolerance mechanisms. Selenium can also enhance cellular functions like membrane stability, mineral nutrition homeostasis, antioxidant response, photosynthesis, and thus improve plant growth and development …

Most of the cultivated, edible mushrooms are selenium deficient, as the selenium content is very low (< 1–8.5 μg Se/g dry weight).In some of the wild grown, edible fungi and mushrooms, the Se content ranges from 12-200 μg/g (Costa-Silva et al. 2011; Falandysz 2008).However, most of the wild grown, edible mushrooms are not amenable …

Selenium (Se) is a trace element essential for both plants and humans ( Ding et al., 2014 ). It has been reported that inorganic Se (Se IV and Se VI) is more toxic than organic Se (SeCys and SeMet), however, the organic forms are safer to use, have antioxidant properties, and can be assimilated by humans.

While some studies suggested an immobilization and reduced plant availability of organic Se, others proposed it as an important plant-available Se pool …

Introduction. Selenium (Se) is an essential trace element for human health. For adults (≥18 years), the recommended nutrient intake (RNI) of Se for both genders in Chinese populations is 60 μg per day (National Health Commission, 2018).Appropriate Se supplementation has been reported to exert anti-viral effects, reduce the levels of thyroid …

ship to the concentration of selenium in plants grown on those soils.' This is because selenium in soil exists in several chemical forms which differ widely in their solubility and availability to plants. These chemical forms are Selenides, Se -7 - Elemental selenium. Se° Selenites, SeOr Selenates, Se04' and Organic selenium.")

Selenium (Se) is a highly essential element, intakes of which in many populations are below the established requirements. As edible mushrooms represent an important part of the human diet in some regions, the present study investigated the concentrations of Se species (Se(IV), Se(VI), Seorg and Setotal) in three cultivated …

grown in soil under glasshouse conditions with two doses of S (0 and 14 mg kg−1) as sulfate and three doses of selenium (0, 1, and 2 mg kg −1 ) as selenate (Se VI ) in a randomized factorial ...

Amending soils with Se-hyperaccumulator plant derived sources of selenium (Se) may be useful for increasing the Se content in food crops in Se-deficient regions of the world. In this study we evaluated total Se and the different chemical species of Se in broccoli and carrots grown in soils amended with ground shoots of the Se-hyperaccumulator ...

To ensure a safe and adequate Se intake, 30 and 4 g fresh leaf material from E. sativa grown with 5 and 10–20 μM Se, respectively or 4 g from D. tenuifolia supplied with 5 μM Se was estimated ...

Selenium (Se) is an essential trace element for humans and animals but at high concentrations, Se becomes toxic to organisms due to Se replacing sulfur in proteins. Selenium biofortification is an agricultural process that increases the accumulation of Se in crops, through plant breeding, genetic engineering, or use of Se fertilizers. Selenium …

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 ).

Selenium (Se) is a micronutrient for animals and humans and is needed for hormone regulation, antioxidant defenses, and immune and muscle systems . The …

Selenium (Se) is an essential micronutrient for human health. Se deficiency affects hundreds of millions of people worldwide, particularly in developing countries, and there is increasing awareness that suboptimal …

assimilation by humans and animals. Selenium species are frequently found in plants in both organic Se compounds (i.e., selenomethionine (SeMet), methyl selenocysteine (MeSe-Cys), selenocysteine (SeCys)) and inorganic compounds (i.e., selenite (SeO3 2), selenate (SeO4 2)) [22]. Selenium bioavailability differs based on the …

Selenium (Se) is an essential trace element for humans and animals but at high concentrations, Se becomes toxic to organisms due to Se replacing sulfur in proteins. ... In plants, Se is not considered as an essential element. In general, concentrations of Se in plants grown in seleniferous soils are less than 25 mg/kg DW (Bell et al., 1992; ...

Selenium (Se) is an important trace element for humans and many animals, as a component of selenoenzymes that display pivotal roles in cell metabolism by functioning as protectors from oxidative stress and controllers of cell redox status (Rayman 2012; Roman et al. 2014).Some organic forms of Se, like selenomethionine (SeMet), …

Crystalline trigonal selenium (t-Se) has been studied as a one-dimensional semiconductor material, as displayed in Fig. S1 [1], [2]. Crystalline t-Se exhibits interesting properties such as an intrinsic p-type conductivity, high resistance (<1 pA) and high photoresponsivity (>0.1 A/W) [3]. In addition, self-formed low dimensional structure can ...

A comprehensive study in selenium (Se) biofortification of staple food is vital for the prevention of Se-deficiency-related diseases in human beings. Thus, the roles of exogenous Se species, application …

The foliar application of selenium (Se) is an effective method for biofortification of Se in crop grains in order to provide sufficient Se for human health. As a staple food in China, the foxtail millet (Setaria italica L.), which had been Se biofortification, would be helpful to overcome Se deficiency in the diet. The Se fertilizer and its …

The synergistic effect of vitamin E and selenium together to enhance the immune system is greater than either alone. A new form of selenium is Se-methylselenocysteine (SeMC), a naturally occurring …

The purpose of this research was to explore the speciation and bioaccessibility of native soil-derived selenium (Se) versus Se applied via fertiliser in the edible portions of maize, groundnut and cowpea grown in Malawi.

Selenium can also accumulate in agricultural soils through the application of Se fertilisers to crops (White et al. 2007b) or irrigation with Se-rich water (Dhillon and Dhillon 2003 ). Ammonium sulphate fertilisers can contain up to 36 mg Se kg −1 (Bisbjerg 1972 ). Phosphate rocks can contain up to 178 mg Se kg −1 and single-superphosphate ...

Abstract As an essential trace element, selenium (Se) plays a tremendous role in the functioning of the human organism being used for the biosynthesis of selenoproteins (proteins containing one or several selenocysteine residues). The functions of human selenoproteins in vivo are extremely diverse. Many selenoproteins have an …
