“…1Beyond achieving increases of total Se concentration in crops, one main task of Se biofortification is to enrich plants with Se compounds that provide health benefits to humans and animals (Fig. 4 ) (Newman et al 2019 ). SeCys and SeMet are important precursors for the synthesis of mammalian selenoproteins, function as direct antioxidants in cells due to their easy oxidation and have a major role in protein repair (Rahmanto and Davies 2012 ).…”

Background Selenium (Se) is an essential element for mammals and its deficiency in the diet is a global problem. Plants accumulate Se and thus represent a major source of Se to consumers. Agronomic biofortification intends to enrich crops with Se in order to secure its adequate supply by people. Scope The goal of this review is to report the present knowledge of the distribution and processes of Se in soil and at the plant-soil interface, and of Se behaviour inside the plant in terms of biofortification. It aims to unravel the Se metabolic pathways that affect the nutritional value of edible plant products, various Se biofortification strategies in challenging environments, as well as the impact of Se-enriched food on human health. Conclusions Agronomic biofortification and breeding are prevalent strategies for battling Se deficiency. Future research addresses nanosized Se biofortification, crop enrichment with multiple micronutrients, microbial-integrated agronomic biofortification, and optimization of Se biofortification in adverse conditions. Biofortified food of superior nutritional quality may be created, enriched with healthy Se-compounds, as well as several other valuable phytochemicals. Whether such a food source might be used as nutritional intervention for recently emerged coronavirus infections is a relevant question that deserves investigation.

“…The humans and animals need in their growth and development several essential nutrients like selenium (Se). This micro-nutrient has distinguished roles in human health as reported by many studies (e.g., Rayman, 2012;Roman et al, 2014;Schomburg, 2016;Vinceti et al, 2017;Dinh et al, 2018;Natasha et al, 2018 andNewman et al, 2019). Selenium can play many biological functions including antioxidant (Wang et al, 2017), antagonistic roles (Jin et al, 2018), immune-regulatory (Dinh et al, 2018) and potentials in cancer prevention (Tan et al, 2019).…”

“…Se is an essential trace element for human and animal health, where it can be covalently incorporated into amino acids, chiefly selenocysteine (SeCys) and selenomethionine (SeMet), and acts as a cofactor for antioxidant enzymes such as glutathione peroxidase, and, in these chemical forms, is involved in the maintenance of the immune system, regulation of thyroid function, brain cognitive function, general antioxidant and detoxification capacity, and anti-cancer and anti-viral effects have also been documented (Hatfield et al, 2014;Ullah et al, 2019). Se deficiency in the human body can lead to serious medical complications, including cataracts, endothelial dysfunction and cardiovascular disease, cardiomyopathy, osteochondropathy, poor immune function, cognitive decline, and even cancer (Natasha et al, 2018;Newman et al, 2019). However, more than about 15% of the world's population suffer from Se deficiency, including in many regions of China, Oceania, Africa, and Europe (Tan et al, 2016;Schiavon and Pilon-Smits, 2017;Dinh et al, 2018).…”

Selenium Biofortification and Interaction With Other Elements in Plants: A Review

et al. 2020

Selenium (Se) is an essential element for humans and animals and its deficiency in the diet is a global problem. Crop plants are the main source of Se for consumers. Therefore, there is much interest in understanding the factors that govern the accumulation and distribution of Se in the tissues of crop plants and the mechanisms of interaction of Se absorption and accumulation with other elements, especially with a view toward optimizing Se biofortification. An ideal crop for human consumption is rich in essential nutrient elements such as Se, while showing reduced accumulation of toxic elements in its edible parts. This review focuses on (a) summarizing the nutritional functions of Se and the current understanding of Se uptake by plant roots, translocation of Se from roots to shoots, and accumulation of Se in grains; and (b) discussing the influence of nitrogen (N), phosphorus (P), and sulfur (S) on the biofortification of Se. In addition, we discuss interactions of Se with major toxicant metals (Hg, As, and Cd) frequently present in soil. We highlight key challenges in the quest to improve Se biofortification, with a focus on both agronomic practice and human health.
