“…In addition to the positive effects elicited by Se in plants subjected to abiotic stress, Se supplementation has been reported to protect plants from biotic stress caused by pathogenic fungi (Kornas et al 2019;Xu et al 2020) and a variety of generalist invertebrates and herbivores (Freeman et al 2007(Freeman et al 2009Quinn et al 2010;Valdez Barillas et al 2011), suggesting that crops enriched with Se may require less synthetic fungicides and pesticides during their cultivation. Therefore, besides being applied to crops to address malnutrition in vulnerable populations, Se might be used to attain agroecological plant protection and sustainable use of agrochemicals.…”

“…Therefore, besides being applied to crops to address malnutrition in vulnerable populations, Se might be used to attain agro-ecological plant protection and sustainable use of agrochemicals. Alternatively, Se could be employed as an ecological insecticide (Mechora 2019 ) or fungicide (Wu et al 2014 ; Xu et al 2020 ). In this respect, Wu et al ( 2014 ) proposed the use of Se in soil for the control of the postharvest disease of fruits and vegetables caused by Penicillium expansum , while Liu et al ( 2019 ) and Xu et al ( 2020 ) endorsed the use of Se for the control of the oilseed rape disease caused by Sclerotinia sclerotiorum .…”

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.

“…Under heat or drought stress, Se plays a critical role in maintaining cereal grain yields [259,260]. Se also protects plants from insect-pest and fungal attacks [261,262]. Figure 4 illustrates many ways in which Se biofortification improves human and animal health [131].…”

The trace element selenium (Se) is a crucial element for many living organisms, including soil microorganisms, plants and animals, including humans. Generally, in Nature Se is taken up in the living cells of microorganisms, plants, animals and humans in several inorganic forms such as selenate, selenite, elemental Se and selenide. These forms are converted to organic forms by biological process, mostly as the two selenoamino acids selenocysteine (SeCys) and selenomethionine (SeMet). The biological systems of plants, animals and humans can fix these amino acids into Se-containing proteins by a modest replacement of methionine with SeMet. While the form SeCys is usually present in the active site of enzymes, which is essential for catalytic activity. Within human cells, organic forms of Se are significant for the accurate functioning of the immune and reproductive systems, the thyroid and the brain, and to enzyme activity within cells. Humans ingest Se through plant and animal foods rich in the element. The concentration of Se in foodstuffs depends on the presence of available forms of Se in soils and its uptake and accumulation by plants and herbivorous animals. Therefore, improving the availability of Se to plants is, therefore, a potential pathway to overcoming human Se deficiencies. Among these prospective pathways, the Se-biofortification of plants has already been established as a pioneering approach for producing Se-enriched agricultural products. To achieve this desirable aim of Se-biofortification, molecular breeding and genetic engineering in combination with novel agronomic and edaphic management approaches should be combined. This current review summarizes the roles, responses, prospects and mechanisms of Se in human nutrition. It also elaborates how biofortification is a plausible approach to resolving Se-deficiency in humans and other animals.

“…An animal study using a chicken model of Se deficiency has demonstrated the negative correlation between Se deficiency and inflammation-related gene expression in skeletal muscles (Wu et al, 2014). Se supplementation can attenuate inflammatory response and lung injury induced by a variety of stimuli, including virus (Liu et al, 2015), bacteria (Xu et al, 2020), and heavy metal (Ghorbel et al, 2017). It was also reported that supplementation of Se to macrophages ameliorates the pro-inflammatory response induced by LPS (Vunta et al, 2008).…”
