[Advances in molecular mechanisms of arsenic hyperaccumulation of Pteris vittata L.]

Arsenic is a toxic metalloid. Arsenic pollution in soils affects food safety and threatens human health. Pteris vittata L. has enormous application value in phytoremediation of arsenic-contaminated soil for its high arsenic hyperaccumulation ability. Understanding the arsenic hyperaccumulation molecular mechanism of P. vittata is the core theoretical basis of phytoremediation technology. This review introduces the omics study on arsenic hyperaccumulation mechanisms, as well as important molecular component that is involved in arsenic hyperaccumulation of P. vittata. Further research directions and trends are also discussed.砷是一种毒性很强的类金属元素，土壤砷污染可引发一系列食品安全问题，进而威胁人类健康。蜈蚣草具有极强的富集砷的能力，在砷污染土壤的植物修复中具有重要的应用价值。深入阐释蜈蚣草超富集砷的分子机制是植物修复技术的核心理论基础。文中综述了蜈蚣草超富集砷的组学研究进展，以及目前鉴定到的砷富集过程中的重要分子元件，并对未来的研究方向和趋势进行了展望。.
