“…However, only selenite and selenate can be absorbed and retained by plants [27]. This mineral is essential for many species of plants as well as for humans, but becomes toxic at higher levels, with the gap between deficiency and toxicity being quite small [103,104]. Until today, it has not been proven that plants require Se for their growth; however, it has been determined that there are beneficial effects of its application in plant species with the particular capability to accumulate high quantities of this element [7,105].…”

“…In order to benefit from Se in these interventions, it is important to consider if the plant species to employ belongs to the group of selenium-hyper accumulators or the non-accumulators, because this categorization will define the ability and resistance of the plant to carry out the expected mediation [104,107]. Se hyperaccumulator species act by sequestering Se available into their peripheral leaves, thus turning leaves into a defence mechanism against herbivory attacks [123].…”

Non-Essential Elements and Their Role in Sustainable Agriculture

Agricultural systems are constantly under environmental pressure, and the continuous rise of the global population requires an increasingly intensification of agronomical productivity. To meet the current global food demand, particularly in depleted ecosystems under adverse climate conditions, the development of novel agronomical practices, which ensure crop productivity while safeguarding minimal impact to the environment, must be encouraged. Since aluminium (Al), cobalt (Co), selenium (Se), silicon (Si) and sodium (Na) are not essential to plant metabolism, their benefits are often neglected or underestimated in agriculture; however, several studies support their advantages in sustainable agriculture when properly employed. The agronomical uses of these elements have been studied in the last decades, delivering important cues for the improvement of food and feed production worldwide due to beneficial effects in plant growth and productivity, nutrient balance, pest and pathogen resistance, water stress management, heavy-metal toxicity alleviation, and postharvest performance. However, their application has not been addressed as part of a holistic conservation strategy that supports the sustainability of agroecosystems. Here, we discuss the potential use of these elements in sustainable agriculture, and the knowledge gaps that hinder their effective integration into agronomical practices, which result in equally profitable applications while supporting environmental sustainability.

“…Plants acquire selenium mainly from soil that plant selenium levels can reflect soil selenium levels (Dinh et al, 2018). Since overdose selenium can be harmful to plants as well, there are usually low selenium levels contained in plants, except those seleniferous areas (Yang et al, 2022). As a result, the most possible reason for a man to have selenium deficiency may be the low soil selenium level.…”

“…Sem is the selenoprotein synthesized mainly by plants as over 90% selenium is stored in this form in plants (Cubadda et al, 2010). Since plants construct the daily dietary of animals, Sem becomes the leading form of exogenous selenium for plant eaters (Yang et al, 2022). On contrast, Sec exists mostly in animal products as the only amino acid synthesized on transfer RNA (tRNA) in eucaryons (Xu et al, 2007).…”

Selenium, as one of the essential microelements, plays an irreplaceable role in metabolism regulation and cell survival. Selenium metabolism and regulation have great effects on physiological systems especially the immune system. Therefore, selenium is tightly related to various diseases like cancer. Although recent research works have revealed much about selenium metabolism, the ways in which selenium regulates immune cells' functions and immune-associated diseases still remain much unclear. In this review, we will briefly introduce the regulatory role of selenium metabolism in immune cells and immune-associated diseases.

Se-rich agro-foods are effective Se supplements for Se-deficient people, but the associated metals have potential risks to human health. Factors affecting the accumulation of Se and its associated metals in Se-rich agro-foods were obscure, and the prediction models for the accumulation of Se and its associated metals have not been established. In this study, 661 samples of Se-rich rice, garlic, black fungus, and eggs, four typical Se-rich agro-foods in China, and soil, matrix, feed, irrigation, and feeding water were collected and analyzed. The major associated metal for Se-rich rice and garlic was Cd, and that for Se-rich black fungus and egg was Cr. Se and its associated metal contents in Se-rich agro-foods were positively correlated with Se and metal contents in soil, matrix, feed, and matrix organic contents. The Se and Cd contents in Se-rich rice grain and garlic were positively and negatively correlated with soil pH, respectively. Eight models for predicting the content of Se and its main associated metals in Se-rich rice, garlic, black fungus, and eggs were established by multiple linear regression. The accuracy of the constructed models was further validated with blind samples. In summary, this study revealed the main associated metals, factors, and prediction models for Se and metal accumulation in four kinds of Se-rich agro-foods, thus helpful in producing high-quality and healthy Se-rich.
