Metal hyperaccumulator plants accumulate and detoxify extraordinarily high concentrations of metal ions in their shoots. Metal hyperaccumulation is a fascinating phenomenon, which has interested scientists for over a century. Hyperaccumulators constitute an exceptional biological material for understanding mechanisms regulating plant metal homeostasis as well as plant adaptation to extreme metallic environments.Our understanding of metal hyperaccumulation physiology has recently increased as a result of the development of molecular tools. This review presents key aspects of our current understanding of plant metal – in particular cadmium (Cd),nickel (Ni) and zinc (Zn) – hyperaccumulation.
金属超积累植物在其地上部分积累和解毒极高浓度的金属离子。金属超积累是一个引人入胜的现象,一个多世纪以来一直吸引着科学家的兴趣。超积累体是理解调节植物金属内稳态以及植物适应极端金属环境的机制的特殊生物材料。随着分子工具的发展,我们对金属超积累生理学的理解最近有所增加。本综述介绍了我们目前对植物金属——特别是镉(Cd)、镍(Ni)和锌(Zn)——超积累的关键方面的理解。
