| Abstract: | 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. |
