植物对重金属镉的吸收与耐受机制研究进展
|
摘要
为了有效降低土壤中镉含量,保障人类健康,人们希望通过一种经济、有效的方法——植物修复技术来治理土壤镉污染。因此,植物对重金属镉的吸收与耐受机制研究,已成为近年来植物逆境生理研究的热点。笔者主要综述了植物对镉的吸收、转运及积累机制,以及植物体通过细胞壁的沉积、细胞区室化、螯合作用和抗氧化系统的保护作用对镉的耐受机制,以期为今后通过植物修复技术更好治理土壤镉污染提供基础资料。
In order to effectively reduce the cadmium content in soil and protect human health, it is hoped that an economical and effective method(phytoremediation technology) can be used to control soil cadmium pollution. Therefore, the study on the mechanism of plant absorption and tolerance to heavy metal cadmium has become a hot spot in plant stress physiology research in recent years. The authors reviewed the mechanisms of cadmium uptake, transport and accumulation of plant, as well as the tolerance mechanism of plant to cadmium through cell wall deposition, cell compartmentalization, chelation and antioxidant system protection, so as to provide basic information for better control of soil cadmium pollution through phytoremediation technology in the future.
