There has been a particular research interest since the first As-hyperaccumulator, Pteris vittata L., was identified. The mechanism of accumulation and metabolism of As in P. vittata can contribute to the optimization of phytoremediation. P. vittata has developed different ecotypes during its long-term evolution process. It is shown that there are significant differences in As accumulation and tolerance among the ecotypes of P. vittata. Based on a systematic analysis of characteristic and mechanism of As accumulation in P. vittata, the present work reviews the latest progress in the effects of different ecotypes on As accumulation in P. vittata. The preliminary result shows that the nonmetallicolous ecotypes possess more effective As accumulation than the metallicolous ecotypes, suggesting that the efficiency of phytoextration can be greatly enhanced by judicious selection of appropriate ecotypes of P. vittata. However, it is still not fully clear how molecular mechanisms are related to accumulation and tolerance of As in different ecotypes of P. vittata. Further studies should concentrate on key functional genes and the process involved in As hyperaccumulation in P. vittata., authors=XU Feifei, MA Xiaona, LUO Wanqing, WU Fuyong, authorsList=XU Feifei,

runingTitle=null, highlight=null, articleAbstract=土壤砷污染是全球尤其是东南亚和中国非常突出且亟需解决的环境问题。自砷超富集植物——蜈蚣草（Pteris vittata L.）发现以来，一直是国内外学者研究的一个热点。深入理解蜈蚣草体内砷代谢和富集机制是有效利用植物修复技术治理砷污染土壤的关键。在长期的自然进化过程中，蜈蚣草逐渐分化出不同生态型。已有研究结果显示：不同生态型蜈蚣草在砷富集和砷耐性等方面均存在明显差异。本文在系统分析蜈蚣草砷富集特征、机理的基础上，重点阐述了生态型差异对蜈蚣草砷富集的影响方面的最新研究进展。研究结果显示：非污染生态型与污染生态型蜈蚣草相比砷富集能力更为高效，说明通过选择性的利用合适的蜈蚣草生态型将明显改善植物修复的效率。不同生态型蜈蚣草砷富集与砷耐性差异的分子机理尚不清楚，相关关键功能基因及其过程尚需深入研究。,
