Summary: The study investigated the effects of selenium biofortification on basil, cilantro, and scallion microgreens. Results showed a significant increase in selenium content in all herbs, with scallions showing the largest increase. Other mineral contents varied among herb species, and antioxidant capacity and total phenol content increased with the highest selenium treatments, although basil and scallions demonstrated decreased crop yield. Overall, biofortified culinary herb microgreens are an ideal functional food for enhancing selenium, dietary minerals, and antioxidants to benefit human health.

Summary: In Se-deficient areas, foliar spraying of selenate or selenite on wheat can effectively increase dietary Se intake. The accumulation of Se in wheat grain is influenced by leaves Se and the transfer of Se from node1 to internode1. The main form of Se in wheat grain is organic Se. The optimal dosage for spraying is 15 g ha-1.

Summary: Biofortification of Brassica oleracea with organic and inorganic selenium resulted in stronger growth stimulation and increased levels of chlorophyll and ascorbic acid. However, the biofortification effect was lower for organic selenium compared to inorganic selenium. Supply of Chlorella increased the efficiency of biofortification with inorganic selenium but had no effect on organic selenium.

Summary: Selenium is an essential micronutrient for mammals, with deficiency posing a serious threat to health. Biofortification strategies have been developed to combat selenium deficiency. While selenium supplementation is beneficial for preventing and treating chronic diseases, the effects may vary depending on individual baseline selenium status.

Summary: This study analyzed the effects of soil and foliar fertilization with sodium selenate (VI) on selenium content in spring wheat grain. The results showed that a combination of soil and foliar fertilization significantly increased selenium content in the grain. The best timing for foliar fertilization treatment was found to be in the stem elongation phase.

Summary: Increasing selenium content in spring wheat grain can be achieved by combining grain and soil fertilization with foliar application at the tillering and stem elongation stages, which resulted in the highest selenium content in the grain. The study showed that the applied biofortification methods contributed to the increase in selenium content in spring wheat grain.

Summary: This study assessed the genetic variability for grain nutrients in a set of 600 pigeonpea germplasms and found significant differences among genotypes for agronomic traits and grain nutrients. Germplasms from the Asian region showed greater variation in grain nutrients, while those from the African region had higher nutrient density.

Summary: Selenium is an essential trace element for animals and humans. Enshi, known as the world capital of Se, has a large Se-excess area. Cardamine enshiensis (C. enshiensis), a Se hyperaccumulation plant discovered in Enshi, has been approved as a new source of food. This review focuses on the discovery and mechanism of Se tolerance and Se hyperaccumulation in C. enshiensis, as well as its potential utilization in Se biofortification agriculture, graziery, and human health.

Summary: This study examined the selenium species composition of four vegetables and found that the proportion of selenium species varies among different plant species and is influenced by soil types. Tomatoes and green peas had higher amounts of organic selenium, while cabbage and carrots had higher proportions of selenate.

Summary: Crop biofortification with inorganic selenium fertilizer is a feasible strategy to improve the health of residents in Se-deficient areas. This study found that appropriate selenite supply can increase rice yield and selenium concentration, while high concentrations can significantly reduce soil nematode abundance.

Summary: Selenium biofortification of aromatic plants is a promising strategy to produce valuable functional food. The experiment demonstrated that selenium treatment increased photosynthetic pigments, pectin, waxes, and macro- and microelements, while decreasing malonic dialdehyde accumulation. However, neither selenate nor nano-Se showed a beneficial effect on essential oil accumulation. Moreover, the study revealed that solar activity has a significant impact on the essential oil yield and composition of aromatic plants.

Summary: Due to severe drought in California, there is a shortage of good quality water for irrigated agriculture. As a solution, saline groundwater and drainage water containing natural-occurring selenium and boron salts are being considered as alternative sources of water for irrigation. A multi-year field study has shown that growing the halophyte-agretti in saline and boron-laden soils and irrigating it with saline and low-saline water can produce selenium-enriched agretti. This finding may promote selenium biofortification strategies in regions with poor water quality.
