植物耐铜的分子机制和微生物学机制
Molecular and Microbial Mechanisms of Plant Response to Copper Stress
摘要
Abstract
At present,soil heavy metal pollution has become a global major environmental issue.Copper(Cu)is an essential trace element for plants,but high concentrations of copper have toxic effects on plants.In order to adapt to copper stress environments,plants have developed various copper-tolerant molecular and microbiological mechanisms.This article introduces the role of hyperaccumulating plants in copper-contaminated soil,systematically outlining the morphological,physiological,molecular,and rhizospheric microbiological mechanisms of plant responses to copper stress,including the following:The physiological defense and absorption transport mechanisms of plants against copper;Plant growth promoting rhizobacteria(PGPR)enhancing plant tolerance to copper stress by promoting plant nutrient absorption and secreting growth-regulating substances;PGPR reducing copper damage to plants by inducing systemic resistance and adsorbing accumulated copper ions;The mechanisms of plant responses to copper stress mediated by rhizospheric microbial community structure and function;And the changes in rhizospheric microbial community structure in response to different copper stresses.This article provides scientific support for the future breeding of copper-tolerant plant germplasm and the management and restoration of copper-contaminated soil.关键词
