有机酸在超积累植物重金属解毒机制中的作用

Function of organic acids in heavy metal tolerance mechanism in hyperaccumulator

有机酸是植物体内一种重要的金属配体,在超积累植物的解毒机制中具有重要作用。文章综述了有机酸参与超积累植物对重金属的吸收、运输、积累和解毒过程的生物学机制,最后对其存在问题进行了分析,并展望了未来的发展方向。

The contamination of heavy metals in soils is a serious problem. Organic acids such as citric, oxalic and/or malic acid,are important metal chelators in hyperaccumulator. A review is given on the participation of organic acids in the absorption ,transport and accumulation of heavy metal tolerance mechanism in hyperaccumulator and existing problems in the recent studies and development propects in the future.
