【摘要】 启动子是基因表达调控的重要顺式元件,综述了高等植物启动子的构成,包括转录起始位点、TATA框和上游启动子元件。并着重从组成型、组织特异型和诱导型启动子3个方面介绍了其结构特征、功能,以及它们在植物基因工程中的应用和研究进展,简述了双向启动子、可变启动子和串联启动子的研究情况,提出植物启动子研究中存在的问题与展望。更多还原

【Abstract】 A lot of plant promoters have been identified and used in the plant transgenic engineering.The characteristics of various cis-regulatory elements of plant promoters,such as TATA-box,transcription start point and upstream elements,and different types of the plant promoter,such as constructive promoter,tissue-specific promoter and inducible promoter,as well as bi-direction promoter,alternative promoter and linked promoter will be described or analyzed in this present paper.更多还原
