植物螯合肽介导植物对镉、砷耐性和积累的研究进展
Research progresses on the role of phytochelatin in mediating the tolerance and accumulation of cadmium and arsenic in plants
摘要
Abstract
In recent years,soil contamination by heavy metals such as cadmium and arsenic has caused toxic effects on food crops,including rice,and seriously threatened food security and ecosystem health.To cope with the toxicity of cadmium and arsenic,plants have evolved various mechanisms,one of which involves the synthesis of some small molecule compounds that chelate with cadmium and arsenic to reduce their toxicity.Phytochelatins(PCs),a class of small molecule polypeptides,play an important role in the detoxification of heavy metals such as cadmium and arsenic.In this review,the latest research progresses on the role of PCs in mediating plant tolerance to and accumulation of cadmium and arsenic are summarized from the aspects of their structure,biosynthesis and functions,with the aim of providing a reference for further in-depth studies on the mechanisms of phytochelatins in plant tolerance and accumulation of heavy metals.关键词
