【摘要】 综述了植物基因启动子的核心结构与功能、植物基因启动子的种类 :异源组成型启动子 (CaMV35S、MMV)和从植物自身克隆的组成型启动子 (PTSB1和PPHYB) ,以及植物中通过按物理因素 (温、光、旱、热等 )、化学因素 (离子、有机物、激素等 )和生物因素 (病菌、组织器官、发育阶段等 )诱导表达的一些启动子 ,发育时期特异的启动子、器官特异的启动子 (根、茎、叶等 )和植物中应用的人工双向启动子的研究进展和应用前景更多还原

【Abstract】 Promoters are the important regulation factors/elements in gene expression.In this paper,the structure and function of promoters are analyzed and reviewed.Plant gene promoters are classified into constitutive promoters,inducible promoters ,tissue (spatial) and developmental (temporary) specific promoters.The bi-directional promoters existed in nature and reconstructed artificially by some strategies are introduced and their applications in plant genetic engineering are prospected.更多还原
