Special Issue Information

Dear Colleagues,

Selenium (Se) is an essential micronutrient for humans and animals, and more than 40 types of diseases have been found to be associated with Se deficiency. Plants are the main source of dietary Se, and while low doses protect plants from a variety of abiotic stresses such as metal stress, high doses of Se pose risks to plant survival. Therefore, important insights are needed to understand the mechanisms of the utilization and metabolism of the chemical form of Se in plants and its bioactivity in plants. Further, it is also critical to evaluate the impact of Se accumulation in plants and its effect on the health of humans and environmental health. This Special Issue will focus on all aspects involving both plants and Se.

The main topics of interest include but are not limited to the following:

  • Collection and characterization of plant genetic resources, including species and genes, in various responses to Se;
  • Chemical forms of Se in plants, involving Se-protein, Se-polysaccharide, and so on, as well as their bio-functions;
  • Mechanisms of the absorption, transport, distribution, accumulation, and efflux of Se in plants;
  • New approaches to the quantification and characterization of Se in plants;
  • Health effect of plant-based food Se supplements on humans and animals;
  • Environmental impact of Se in soil and water and phyto/bioremediation approaches to address environmental concerns.

Selenium is an essential trace element which plays an important role in human immune regulation and disease prevention. Plants absorb inorganic selenium (selenite or selenate) from the soil and convert it into various organic selenides (such as seleno amino acids, selenoproteins, and volatile selenides) via the sulfur metabolic pathway. These organic selenides are important sources of dietary selenium supplementation for humans. Organoselenides can promote plant growth, improve nutritional quality, and play an important regulatory function in plant ecosystems. The release of selenium-containing compounds into the soil by Se hyperaccumulators can promote the growth of Se accumulators but inhibit the growth and distribution of non-Se accumulators. Volatile selenides with specific odors have a deterrent effect on herbivores, reducing their feeding on plants. Soil microorganisms can effectively promote the uptake and transformation of selenium in plants, and organic selenides in plants can improve the tolerance of plants to pathogenic bacteria. Although selenium is not an essential trace element for plants, the right amount of selenium has important physiological and ecological benefits for them. This review summarizes recent research related to the functions of selenium in plant ecosystems to provide a deeper understanding of the significance of this element in plant physiology and ecosystems and to serve as a theoretical basis and technical support for the full exploitation and rational application of the ecological functions of selenium-accumulating plants.

Selenium (Se) is an essential trace element for humans and animals, and it plays an important role in immune regulation and disease prevention. Tea is one of the top three beverages in the world, and it contains active ingredients such as polyphenols, theanine, flavonoids, and volatile substances, which have important health benefits. The tea tree has suitable Se aggregation ability, which can absorb inorganic Se and transform it into safe and effective organic Se through absorption by the human body, thereby improving human immunity and preventing the occurrence of many diseases. Recent studies have proven that 50~100.0 mg/L exogenous Se can promote photosynthesis and absorption of mineral elements in tea trees and increase their biomass. The content of total Se and organic selenides in tea leaves significantly increases and promotes the accumulation of polyphenols, theanine, flavonoids, and volatile secondary metabolites, thereby improving the nutritional quality of tea leaves. This paper summarizes previous research on the effects of exogenous Se treatment on the growth and quality of tea trees to provide a theoretical basis and technical support for the germplasm selection and exploitation of Se-rich tea.
