摘　　要：植物组织特异性启动子能够调控优良基因在特定器官或组织中表达,具有与基因特异表达相关的结构元件。研究发现,其在调节植物生长发育过程、抵抗生物和非生物胁迫等方面具有重要作用。本文分类概述了近年来植物不同组织特异性启动子的结构特征及调控作用的最新研究进展,并对今后组织特异性启动子研究方向进行展望。Tissue-specific promoters can regulate excellent gene expression in certain organs or tissues,with some structural elements relevant to gene-specific expression.Many researches indicated that tissuespecific promoters play critical roles in regulating plant growth and development processes and improving plant resistance to biotic and abiotic stresses.In the present paper,the latest research advances on structural features and regulating functions of tissue-specific promoters were reviewed and the research direction regarding tissue-specific promoters were also prospected.
