“…In tomato, addition of a high Si dose (1 mM) significantly decreased root concentration of Se at pH 3, but had no effect at higher (up to 8) pH ( Wang et al, 2019 ). Such pH-dependent disparity on Si effect could partially be explained by Si-influx transporter affinity for Se form available at the given pH.…”

Silicon (Si) is not classified as an essential element for plants, but numerous studies have demonstrated its beneficial effects in a variety of species and environmental conditions, including low nutrient availability. Application of Si shows the potential to increase nutrient availability in the rhizosphere and root uptake through complex mechanisms, which still remain unclear. Silicon-mediated transcriptional regulation of element transporters for both root acquisition and tissue homeostasis has recently been suggested as an important strategy, varying in detail depending on plant species and nutritional status. Here, we summarize evidence of Si-mediated acquisition, uptake and translocation of nutrients: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), boron (B), chlorine (Cl), and nickel (Ni) under both deficiency and excess conditions. In addition, we discuss interactions of Si-with beneficial elements: aluminum (Al), sodium (Na), and selenium (Se). This review also highlights further research needed to improve understanding of Si-mediated acquisition and utilization of nutrients and vice versa nutrient status-mediated Si acquisition and transport, both processes which are of high importance for agronomic practice (e.g., reduced use of fertilizers and pesticides).

“…Wheat genotype 'Puelche' is the most Se-tolerant and has the greatest Se accumulation among the three wheat genotypes studied (i.e., 'Puelche', 'Tinto', and 'Kumpa'), such that its Se accumulation was related to the strongest transcript level of the sulfate transporter TaeSultr4.1 in roots [87]. In addition, other transporters also take part in Se transport, such as silicon transporters in rice [88] and tomato [89], phosphate/orthophosphate transporters in wheat [90], rice [91][92][93], tomato [89], and yeast (Saccharomyces cerevisiae) [94,95], and monocarboxylates transporters in yeast (S. cerevisiae) [96]. Thus, it is reasonable to explain the experimental results that plant availability of selenate and selenite was influenced by the competing ions phosphate and sulfate [97,98].…”

Selenium (Se) is essential for human health, however, Se is deficient in soil in many places all around the world, resulting in human diseases, such as notorious Keshan disease and Keshin–Beck disease. Therefore, Se biofortification is a popular approach to improve Se uptake and maintain human health. Beneficial microorganisms, including mycorrhizal and root endophytic fungi, dark septate fungi, and plant growth-promoting rhizobacteria (PGPRs), show multiple functions, especially increased plant nutrition uptake, growth and yield, and resistance to abiotic stresses. Such functions can be used for Se biofortification and increased growth and yield under drought and salt stress. The present review summarizes the use of mycorrhizal fungi and PGPRs in Se biofortification, aiming to improving their practical use.

“…Though, selenate is the main form of Se taken up by plants, and its transport across cell membranes is an energy-dependent process mediated by the sulphate transport system (Lima et al 2018; Schiavon and Pilon-Smits 2017a; White 2018). Competition events in soil between sulphate and selenate, as well as plant sulphate transporters (SULTR) differing in affinity for these two anions, influence the rate of selenate uptake by plants (El Mehdawi et al 2018;White et al 2004, White 2016 (Wang et al 2019;Zhao (FJ) et al 2010, b), while HSeO 3 − and part of SeO 3 2− mainly use lowand high-affinity P transporters (OsPT2), respectively (Zhang et al 2014).…”

“…Competition events in soil between sulphate and selenate, as well as plant sulphate transporters (SULTR) differing in affinity for these two anions, influence the rate of selenate uptake by plants (El Mehdawi et al 2018 ; White et al 2004 , White 2016 ). Selenite compounds instead, are conveyed over plant cell membranes via phosphorus (P) and silicon (Si) transporters, with differences between selenite anion (SeO 3 2− ), hydrogenselenite ion (HSeO 3 − ), and selenous acid (H 2 SeO 3 ) (Wang et al 2019 ; Zhang et al 2014 ). Precisely, H 2 SeO 3 is transported by Si transporters (LSI1) and aquaporins (OsNIP2;1) (Wang et al 2019 ; Zhao (FJ) et al 2010 , b ), while HSeO 3 − and part of SeO 3 2− mainly use low- and high-affinity P transporters (OsPT2), respectively (Zhang et al 2014 ).…”

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.
