摘　　要：土壤盐碱化是限制植物生长发育和阻碍农业生产力的重要非生物胁迫之一。本文从离子毒害、渗透胁迫、活性氧胁迫和高pH胁迫4个方面综述了盐碱胁迫对植物的危害。为了应对盐碱胁迫,植物进化出一系列的调控机制以缓解胁迫危害。从渗透调节物质的合成、离子的吸收转运调节、活性氧清除机制和外源物质调节方面梳理了植物耐盐碱的生理机制;从植物盐碱胁迫的信号转导途径、耐盐碱相关基因的表达和转录因子调控方面概述了植物耐盐碱的分子机制。对利用多组学分析更全面进行植物耐盐碱机制研究做出展望。Soil salinization is a major abiotic stress that limits plant growth and crop yields.In this paper,we summarized the harm of saline-alkali stress to the plant from ion toxicity,osmotic stress,reactive oxygen stress and high pH value stress.To cope with salt-alkali stress,the plant have evolved complex mechanisms to alleviate stress hazards.The physiological mechanisms of plant salt-tolerance were reviewed in osmotic adjustment substance synthesis,ion absorption and transport regulation,reactive oxygen scavenging mechanism and exogenous substance regulation.The molecular mechanisms of plant salt tolerance were summarized from the aspects of signal transduction pathway and the expression of plant salt-tolerance-related gene and transcription factor regulation.The multi-omics analysis application in the comprehensive study on plant salineal-kali tolerance mechanism was prospected.
