“…This may be associated with the positive effects of low doses of Se. These findings are in line with those results by Godina et al (2018) for tomato and Ei et al (2020) for rice, which indicated improved production at low Se contents. Nevertheless, the above-mentioned agronomic traits of R171 increased with the Se application rates increased.…”

Mineral nutrient malnutrition, especially deficiency of selenium (Se) affects the health of approximately one billion people worldwide. Wild emmer wheat (Triticum turgidum ssp. dicoccoides), the progenitor of common wheat, harbors a rich genetic diversity for mineral nutrients. The study was conducted on two wild emmer wheat genotypes differing in Se tolerance (R113, Se-sensitive; R171, Se-tolerant) with 2 Se application methods and 3 Se levels (foliar rates of 0, 11.5 and 23 mg. L-1 ; fertigation rates of 0, 5 and 10 mg. kg-1) in 2017 having 5 replications, at an experimental farm, Sichuan Province, China. It evaluated the effects of Se application on wild emmer wheat growth, grain yield and quality, and 14 other trace elements absorption and translocation in sink-source organs (flag leaves, husks and grains). The results showed that both foliar Se and fertigated Se application methods increased Se contents in sink-source organs, wheat health benefits and yield, while the foliar application was more effective than fertigation. Moreover, two Se application methods decreased toxic trace elements (Pb, Al, As, Li and Cd) contents in wheat, indicating a possible antagonistic effect. Accordingly, this study provided useful information concerning agronomic biofortification of wheat, indicating that it is feasible to apply Se in fertilization programmes to inhibit the heavy metal elements contents and improve yield and quality in agricultural crops. The higher Se, Fe, Zn and Mo contents found in R171 suggested that its germplasm conferred higher abilities for mineral uptake and accumulation, which can be used for genetic studies of wheat nutritional value and for further improvement of domesticated cereals.

“…Очевидно, что дефицит селена вызовет нарушение работы антиоксидантной системы и повреждение клеток организма свободными радикалами. Недостаточность селена может провоцировать патологию разных органов и систем, вызывать злокачественные заболевания [9,23,24]. Дефицит Se приводит к болезни Кашина-Бека (остеоартроз с множественной деформацией суставов, позвоночника и конечностей), болезни Кешана (эндемическая миокардиопатия), анемии, наследственной тромбастении [9,25].…”

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.

“…Differently, other types of agricultural fortification methods, like soil supplementation or foliar spraying with micronutrients, appeared to have positive effects on germination [ 34 , 35 , 49 ]. An extensive report on the effect of Zn-biofortified rice seeds on grain yield was conducted under field conditions in six countries [ 34 ].…”

“…The results of multilocation field studies over a two-year time course evidenced that seeds biofortified with Zn showed enhanced crop productivity with beneficial effects on seed germination, seedling vigor, and overall crop establishment [ 34 ]. In another study, the impact of Zn, selenium (Se), and the simultaneous application of the two micronutrients, were investigated in terms of seedling vigor in biofortified rice [ 35 ]. Zn and Se were added to the soil as solution of sodium selenite and zinc sulfate fertilizers at different concentrations and combinations (0, Zn5, Zn10, Zn15, Se1, Zn5 + Se1, Zn10 + Se1, and Zn15 + Se1).…”

“…Although currently there are still only a handful of studies looking into this particular aspect, the information gathered from transcriptomics analyses can provide useful insights into the molecular players governing both traits, along with the identification of potential biomarkers to test seed quality. Several studies reported poor germination in different lines of biofortified rice [ 31 , 32 , 33 ], while in other cases, agricultural biofortification (e.g., soil or foliar application of zinc or selenium) proved to be beneficial for germination [ 34 , 35 ]. The current advances in omics can now provide tools and techniques for the efficient exploration of genetic resources along with a better understanding of the molecular mechanisms involved in trait development.…”

Hidden hunger, or micronutrient deficiency, is a worldwide problem. Several approaches are employed to alleviate its effects (e.g., promoting diet diversity, use of dietary supplements, chemical fortification of processed food), and among these, biofortification is considered as one of the most cost-effective and highly sustainable. Rice is one of the best targets for biofortification since it is a staple food for almost half of the world’s population as a high-energy source but with low nutritional value. Multiple biofortified rice lines have been produced during the past decades, while few studies also reported modifications in germination behavior (in terms of enhanced or decreased germination percentage or speed). It is important to underline that rapid, uniform germination, and seedling establishment are essential prerequisites for crop productivity. Combining the two traits, biofortified, highly-nutritious seeds with improved germination behavior can be envisaged as a highly-desired target for rice breeding. To this purpose, information gathered from transcriptomics studies can reveal useful insights to unveil the molecular players governing both traits. The present review aims to provide an overview of transcriptomics studies applied at the crossroad between biofortification and seed germination, pointing out potential candidates for trait pyramiding.
