Abstract: With the development of molecular biology, the research of plant salt-tolerance has been extended into many domains, including gene cloning, analysis of gene structure and function and feature of gene expression, etc. Alfalfa is comparatively a more salt-tolerant plant. By cloning the salt-stress-induced genes of the plant, and analyzing the functions of its products, we could not only further our understanding of the molecular mechanism of plant salt-tolerance, but also have an applicable prospect in plant genetic engineering open to us. The present paper summarizes a research on the advancement of salt tress nduced genes.

Key words: Alfalfa, Gene of related tolerate salinity stress, Gene cloning

摘要: 随着植物分子生物学的快速发展,对植物耐盐性的研究已深入到耐盐相关基因的克隆、基因结构与功能的分析及其表达特性的研究。紫花苜蓿(Medicago sativa)是比较耐盐的植物,从苜蓿中分离克隆耐盐相关的基因,分析其结构与功能。不仅可以加深对耐盐分子机制的认识,而且在植物基因工程领域具有重要的应用前景。本文综述了苜蓿盐诱导相关基因的研究进展。
