摘　　要：盐胁迫对植物生长的影响主要表现在离子毒害、渗透胁迫以及次级氧化胁迫等,植物遭受盐胁迫时迅速启动相关基因,进行转录调控,进而合成相应蛋白质来控制代谢物合成和离子转运以调节渗透平衡。随着现代分子生物学迅速发展,对植物耐盐机理研究也深入到了转录组、蛋白质组、代谢组及离子组等水平,"组学"研究为耐盐基因鉴定及标志性代谢物的挖掘等提供了有力手段。该文对近年来国内外有关转录组学、蛋白质组学、代谢组学、离子组学的主要研究方法及在盐胁迫中的应用研究进展进行综述,以揭示植物耐盐机理,为优良耐盐碱植物的筛选与培育提供支持。The effects of salt stress on plant growth were mainly caused by ion toxicity,osmotic stress and secondary oxidative stress.The expression of the related gene activated rapidly and carried out transcriptional regulation,then the corresponding protein is synthesized to control metabolite synthesis and ion transport to regulate the osmotic balance when plants under salt stress.With the rapid development of modern molecular biology,the study of salt tolerance mechanism of plants under salt stress has also deepened to the level of transcriptome,proteome,metabolome and ionome.The＂omics＂research of plants under salt stress provided a powerful tool for salt tolerance gene identification and the mining of iconic metabolites.This paper mainly summarized the methods and the application of transcriptomics,proteomics,metabolomics and ionomics under salt stress.The mechanism of salt tolerance was revealed,which provided a support for the selection and cultivation of excellent salt-tolerance plants.It also has an important theoretical and practical value.
