“…Song et al (2014) found that ABC transporters can sequester As(III)-PCs complexes into vacuoles in both Arabidopsis and rice. Chauhan et al (2020) showed that the up-regulation of ABC transporters, ATPases, STAR1 protein, and 14-3-3 protein during As and Se co-exposure on both the transcriptome and proteome levels, some of which are also effective in limiting aluminum toxicity, indicating that Se can influence a reduction of As accumulation in rice by these means of facilitated vacuolar sequestration. The higher expression of regulation of WRKY, AUX/IAA, and MYB transcription factors that link to As tolerance and reduced expression of phosphate transporters, reducing As uptake, during As and Se co-exposure were also observed (Figure 2).…”

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.

“…Selenium is specifically present as seleno-L-cysteine in a multitude of selenoproteins [114]. These proteins are crucial in repairing oxidized residues and modulating oxidative stress through natural biological oxidant detoxification [115,116]. It has been appraised that between five hundred million and one billion of the world's population suffer from Se deficiency, but on the other hand, selenium is toxic in high concentrations, so the line between the toxicity of Se to humans and Se-deficiency is critical [113].…”

Usage of Si, P, Se, and Ca Decrease Arsenic Concentration/Toxicity in Rice, a Review

Rice is one of the most important routes for arsenic to enter the human food chain and threatens more than half of the world’s population. In addition, arsenic-contaminated soils and waters increase the concentration of this element in various tissues of rice plants. Thus, direct or indirect—infecting livestock and poultry—increase diseases such as respiratory diseases, gastrointestinal tract, liver, and cardiovascular diseases, cancer, and ultimately death in the long term. Therefore, finding different ways to reduce the uptake and transfer of arsenic by rice would reduce the contamination of rice plants with this dangerous element and improve animal and human nutrition and ultimately disease and mortality. In this article, we aim to take a small step in improving sustainable life on earth by referring to the various methods that researchers have taken to reduce rice contamination by arsenic in recent years. Adding micronutrients and macronutrients as fertilizer for rice is one way to improve this plant’s growth and health. In this study, by examining two types of macronutrients and two types of micronutrients, their role in reducing arsenic toxicity and absorption was investigated. Therefore, both calcium and phosphorus were selected from the macronutrients, and selenium and silicon were selected from the micronutrients, whose roles in previous studies had been investigated .

“…Consumption of these contaminated plants by humans and animals causes accumulation of these toxic pollutants. Plant roots provide a way for the entry of HMs present in the environment and translocate them in above ground parts that hampers the normal functioning and physiology of plants and leads to stunted growth (Chauhan et al 2020). Loss of soil fertility, marked decrease in agricultural yield and reduction of microbial diversity and activity of microbes is the result of HMs pollution in soil (Kushwaha et al 2015).…”

“…Amelioration of HMs through phytoremediation include; phytoextraction (use of metal accumulators for the removal of toxic HMs in soil), phytovolatilization (production of volatile metal derivatives and evaporation through aerial parts), phytostabilitzation (plants decrease the bioavailability of toxic metals in soils) and rhizofiltration (exclusion of toxicants from polluted water either through roots of plant or microorganisms associated with the rhizosphere). Exposure of HMs induces plants to activate their defense machinery in several ways like immobilization, compartmentalization of the complexed metal ions, exclusion, and the expression of stress responsive proteins and hormones (Chauhan et al 2020). Plant-microbe interactions make the process of phytoremediation more efficient.…”
