紫花苜蓿耐盐相关基因克隆研究进展

Research on the Advancement of Salt Tolerant Gene in Alfalfa

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。

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-stress-induced genes.
