Advances in the study of genetic enrichment of selenium in plants

Selenium (Se) is a micronutrient essential for human and animal health. Due to the unbalanced distribution of Se resources in the world, Se deficiency is regarded as a major human health problem. Insufficient ingestion of Se in human caused a series of disease including Keshan disease and Kashin-Beck's disease. While some parts of the world was Se poisoning due to the Se ores on geological stratification or Se pollution. The using Se-enriched and/or hyperaccumulated green plants to treat these problems has acquired more and more attention worldwide from last decade. This paper describes current advances in the efforts of searching Se enriched plant genetic resources, clarifying the Se metabolism and accumulation mechanism in plants, and cloning key genes responsible for Se accumulation or hyper-accumulation and their transformation in plants.
