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.

“…Rapid industrialization and hazard dumping of disposal wastes have enhanced the contamination of potential toxic metals (PTMs) to soils, causing public concerns about crop production, food safety and human health [1][2][3]. Among the PTMs, cadmium (Cd) is highly toxic and results in widespread pollution due to its extensive distribution and mobility in the environment [4,5].…”

Cadmium (Cd) is a toxic trace metal that has polluted 20% of agricultural land in China where its concentration exceeds the standards for Chinese farmland. Plants are capable of accumulating Cd and other trace metals, but this capacity varies with species and cultivars within a species. Rice is a staple food consumed by half of the global population. In order to select safe late rice cultivars that are suitable late rice cultivars that can be cultivated in for growing in slightly contaminated soil, a two-year field experiment was conducted with 27 in the first year and 9 late rice cultivars in the second year. The results showed that plant Cd concentrations varied among the cultivars, with high magnitudes of variation occurred in straw and grains. Five genotypes including LR-12, LR-17, LR-24, LR-25 and LR-26 were identified as low accumulators for the first year while LR-15 and LR-17 were identified as promising cultivars based on Cd concentration in the polished rice grains (<0.02 mg kg−1 DW). In addition, these cultivars had favorable traits, including mineral nutrition and grain yield. Therefore, these genotypes should be considered for cultivation in slightly or moderately Cd contaminated soils.

“…Compared to other organic materials, biochar is attractive in quality and inexpensive to remediate heavy metal contamination; however, the immobilizing effect depended on soil conditions, such as CEC and pH [9][10]. The clay mineral amendment such as diatomite belongs to an aluminosilicate mineral and has the characteristics of a large surface area and light porosity [11]. Diatomite could promote the immobilization of heavy metals by ion exchange and adsorption, thereby reducing heavy metal mobility and bioavailability.…”

Cadmium (Cd) contamination in agricultural soils has caused serious environmental risks and public health concern; possible eco-friendly immobilization technologies are required to reduce Cd accumulation. A set of pot experiments was carried out with two genotypes of Artemisia selengensis grown in a Cd-contaminated soil, which was amended with hydrated lime (L), diatomite (D) and biochar (B), either alone or in combination, to investigate the impacts of these passivators on bioavailability and mobility of Cd in soil and crops. The results demonstrated that hydrated lime and diatomite significantly promoted the immobilization of soil Cd and decreased the accumulation of Cd in Artemisia selengensis, and biochar significantly increased Artemisia selengensis yield. The residual fraction of Cd was increased 1.35~1.51 times for Fuqiu Artemisia selengensis and 0.97~1.05 times for Dayeqing Artemisia selengensis, respectively, under the hydrated lime (L) and hydrated lime+diatomite+biochar (LDB) treatments. Correspondingly, Artemisia selengensis yields were increased by 44.45%~52.50% and 37.91%~43.36%, respectively, in the treatments of biochar (B) and combination amendment (LDB). The results indicate that combination passivators (LDB) are recommended in practical applications, given their high efficiency for soil remediation and potential benefits. Fuqiu Artemisia selengensis, rather than Dayeqing Artemisia selengensis, are suggested to be employed for plants in mildly Cd-contaminated soil to ensure vegetable safety. These findings provide stronger evidence and theoretical support for in situ remediation of Cd-contaminated soil.
