摘  要:
我国土壤砷污染形势严峻,威胁我国粮食安全和居民健康。蜈蚣草是世界上第一种被发现的砷超积累植物,也是为数不多的、成功应用于土壤砷污染修复的植物。对蜈蚣草砷富集分子机制开展研究,可为提高植物修复效率提供理论基础。本文介绍了蜈蚣草砷富集的分子机制,重点阐述了蜈蚣草中参与砷代谢的关键基因及其功能,并展望了相关研究的发展趋势。

摘  要:
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 ex-traordinary fern. This review introduced the molecular mechanisms of As hyperaccumulation, emphasizing on the critical genes that involvedin As metabolism. Knowledge gaps and further studies in future were also discussed.
