“…This primary Se absorption difference is due to regulation of transporters resident in the plasma membrane of root cells. Recently, Liang et al (2019) demonstrated that a low concentration of Se in the supply medium induces the expression of OsNIP 2;1, which may serve as a strong positive regulator of Se transport in rice.…”

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.

“…Therefore, a more economical and "eco-friendly" way to raise Se content needs to develop. Liang et al [60] showed that the Se-rich rice was able to accumulate more abundance of Se under a low Se environment comparing to the Se-free rice. So, the three rice varieties in this experiment had a strong selenium enrichment capacity that can plant as selenium-enriched and high-yield rice varieties.…”

In this study, three japonica rice varieties—Nanjing 9108, Jiahua 1 and Wuyunjing 29—were supplied with different levels of nano-foliar selenium fertilizers (0, 40 and 80 kg Se ha−1) under field conditions. Their rice yield and absorption, accumulation, transportation and utilization of selenium were studied to find suitable selenium-rich rice cultivars and optimal selenium supply levels, while providing references for the development of selenium-rich rice. On an average basis, the Nanjing 9108, Jiahua 1 and Wuyunjing 29 yielded 8755 ± 190, 8200 ± 317 and 9098 ± 72.7 kg ha−1, respectively. The selenium content in polished rice of the three rice varieties is between 0.210 and 0.933 mg kg−1. When 40 g Se ha−1 nano-selenium fertilizer was used, the selenium accumulation in the shoots of Nanjing 9108, Jiahua 1 and Wuyunjing 29 was, respectively, 11.4 g Se ha−1, 12.3 g Se ha−1 and 12.2 g Se ha−1, and when 80 g Se ha−1 selenium fertilizer was applied, the total selenium accumulation of three rice varieties was, respectively, 2.45, 1.75 and 2.40 times that of 40 g Se ha−1 selenium fertilizer. No evident diversity was observed in the selenium transport coefficient and the apparent utilization rate of selenium among the three varieties. The three rice varieties in this experiment had a strong selenium enrichment capacity, and they could be planted as selenium-enriched and high-yield rice varieties. Further, the amount of selenium fertilizer should not exceed 40 g Se ha−1.

Introduction. As a trace element, selenium is present in humans as part of selenoproteins. It improves the work of the antioxidant defense system and produces a strong immunomodulatory effect. Selenium is part of about 30 biologically active compounds of human body. However, selenium deficiency is considered a global problem. The research objective was to determine the selenium content in the developed pasta products. Study objects and methods. The study featured laboratory samples of pasta made from a mix of whole wheat spelt flour, buckwheat, and low-temperature drying powders of broccoli and celery. The selenium content was determined by atomic absorption spectroscopy with electrothermal atomization with a palladium nitric acid matrix modifier. The experiment employed a Hitachi 180-80 atomic absorption spectrophotometer. To determine the selenium content, the samples underwent wet mineralization in nitric and perchloric acids. Adding hydrogen peroxide and ethanol made it possible to convert selenium from inorganic and organic forms into selenite ions. Results and discussion. The research involved domestic natural raw materials. The components proved to be good sources of selenium, which means that they can be used to produce functional products. The selenium content ranged from 105.7 ± 22 mkg/kg to 302.5 ± 17 mkg/kg in the samples. Taking into account the loss of selenium during cooking, the selenium content in 100 g of the finished product ranged from 13.5% to 38.5 %. Conclusion. The developed pasta products proved excellent sources of selenium. The use of buckwheat flour and vegetable powders in the formulation of wholegrain spelt dough increased the selenium content in the pasta by 40.7–186.2 %. The obtained results can be used for tables of the chemical composition of Russian food products.
