摘 要 ：在各种环境胁迫中,盐胁迫是造成作物减产的严重环境因素之一。随着植物分子生物学快速发展,植物耐盐性研究已深入到耐盐相关基因的克隆、基因的结构分析以及基因表达领域。文中就与植物耐盐性密切相关的小分子渗透物质、晚期胚胎发生富集蛋白(LEA)、通道蛋白、盐胁迫相关基因、信号传导基因和转录因子研究作了综述。同时对植物耐盐性研究作了简单的展望。

Abstract:Among various abiotic stresses,the salt stress is one of the most severe environmental factors responsible for the reduction of crop yield.With the development of molecular biology,the research of salt stress made great progress in gene cloning,analysis of its structure and gene expression.This paper reviewed small molecular osmotic substances,Late embryogensis abundant proteins,channel proteins,salt stress-related genes,signal transduction genes,transcriptional factors.Meanwhile prospects for the research are provided.
