| Abstract: |
| Increasing arsenic(As) pollution in soils is of great concern in China, impacting food safety and threatening human health. Pteris vittata, the first known As hyperaccumulator, is among few plants that have been successfully used to remediate As contaminated soils. To further improve phytoremediation by P. vittata, it is necessary to investigate the molecular mechanism of As hyperaccumulation in this extraordinary fern. This review introduced the molecular mechanisms of As hyperaccumulation, emphasizing on the critical genes that involved in As metabolism. Knowledge gaps and further studies in future were also discussed. |
