植物抗病相关启动子及其研究进展

Progress in Plant Promoters Related to Disease Resistance

启动子是调控基因表达的重要顺式元件。植物抗病相关启动子的调控特性研究、分离及其应用对于提高植物抗病性极其关键。本文综述了植物基因启动子的基本结构、克隆方法,着重介绍了组成型、组织特异型、天然与人工合成的病原诱导型启动子的研究进展,及其在植物抗病基因工程中的应用现状和存在问题,并展望了植物抗病相关启动子的应用前景。

Plant promoters are important c/s-regulatory elements for regulating gene expression. Studies on character, isolation and application of plant promoters related to disease resistance are pivotal to enhance plants disease resistance. In this paper, the basic structure and cloning methods of plant promoters were reviewed. The advances on isolation method, application and existed problems of constitutive, tissue-specific promoters, and natural and artificially synthetic pathogen-inducible promoters in plant were introduced in details. The prospect in the study of promoters related to disease resistance was sketched.
