Characterisation of heavy metal transport genes in the plant Arabidopsis: potential roles in metal detoxification and accumulation. Plants have considerable potential for the bioremediation ("phytoremediation") of contaminated soils, including soils polluted with heavy metals. Progress has been made in understanding the physiological and biochemical mechanisms by which plants accumulate and detoxify heavy metals. One important aspect of metal detoxification is the transport of metals across cell membranes. The recently completed genome project for the model plant Arabidopsis has identified a family of genes encoding heavy metal transport proteins. This project aims to investigate the roles of these genes in metal detoxification. In the longer term this knowledge can be applied to the improvement of phytoremediation processes.

拟南芥中重金属转运基因的特征：在金属解毒和积累中的潜在作用。植物在受污染土壤（包括受重金属污染的土壤）的生物修复（“植物修复”）方面具有相当大的潜力。植物积累和解毒重金属的生理生化机制已取得进展。金属解毒的一个重要方面是金属穿过细胞膜的运输。最近完成的模式植物拟南芥的基因组计划已经确定了一个编码重金属转运蛋白的基因家族。该项目旨在研究这些基因在金属解毒中的作用。从长远来看，这方面的知识可以应用于改善植物修复过程。
