摘要:

启动子是调控基因表达的重要顺式元件, 在植物基因表达调控过程中起着重要作用。目前植物抗逆基因工程中, 人们大多使用组成型表达启动子驱动目的基因的表达。组成型表达启动子虽然能提高转基因植株的抗逆性, 但是其持续过量地表达转化的外源基因会阻碍植物的生长且减少其产量。因此, 只在胁迫条件下才会驱动外源基因表达的诱导型启动子的研究显得尤其重要, 已成为目前研究的热点。文章综述了受非生物逆境和生物逆境胁迫诱导的植物基因启动子的种类和功能, 并展望了植物逆境诱导启动子的研究方向和前景。

关键词: 逆境, 诱导型启动子, 功能分析

Abstract:

Promoter is an important cis-regulatory element for gene expression and plays an important role in the process of plant gene expression and regulation. Constitutive promoters are being used to drive alien gene expression in most transgenic engineering. Although constitutive promoters can improve resistance of transgenic plants to abiotic stresses, over- and constitutive-expression of the alien genes have been shown to cause stunted growth and reduction of yield in transgenic plants. Therefore, inducible promoters, which are expressed only when exposed to stresses, are of importance. This paper reviews the types and functions of plant gene promoters induced by bio- and abio-stresses. The prospect of stress-induced promoters was discussed.
