植物组织特异性启动子研究进展

Research Advances of Plant Tissue Specific Promoters

在植物生长发育的不同阶段和植物与环境的互作过程中,其结构和形态会发生极大变化。这些变化是由一系列基因在特定组织、特定时间表达所控制,这一精准的调控"开关"就是植物组织特异性启动子。基于这类启动子表达部位专一的特性,目前在模式植物(拟南芥、烟草)、粮食作物(玉米、水稻、小麦等)和经济作物(棉花、油菜、花生等)中均有大量的研究。综述了植物组织特异性启动子的研究近况,并展望分离鉴定和应用组织特异性启动子的创新性研究途径。

During the different development stages and interaction with environment,plant structure and morphology will change dramatically.These changes are controlled by a set of genes expressed in specific spatial and temporal profile.The precise"switch on"is plant tissue specific promoter.Due to the tissue specificity of these promoters,there are currently a great deal of researches on model plants(Arabidopsis thaliana,Nicotiana tabacum),food crops(Zea mays,Oryza sativa,Triticum aestivum,etc.)and economic crops(Anemone vitifolia Buch,Brassica napus,Arachis hypogaea,etc.).This paper reviewed the advances of plant tissue specific promoters and prospected innovative approaches for isolation and application of tissue specific promoters.
