摘要:
为了解乙烯生物合成调控机理,本研究利用聚合酶链式反应技术,从番茄Micro-Tom中克隆2A11果实特异型启动子和LeHB-1基因,构建LeHB-1正义和反义果实特异表达载体,并导入根癌农杆菌GV3101中,为下一步通过转基因操作来研究转录因子LeHB-1在果实发育过程中的生物学功能奠定了实验基础。

Abstract:
ACO is a key enzyme in the biosynthesis of ethylene. LeHB-1 is the transcription factor of tomato gene ACO1. By studying the activity of transcription factor LeHB-1, one can understand the regulation mechanism of ethylene synthesis. In this study, the sequences of fruit-specific promoter 2A11 and LeHB-1 gene were cloned from tomato by PCR. Then the sense and antisense fruit-specific expression vectors of LeHB-1 were constructed and transformed into Agrobacterium GV3101, and then the plant with the transformation of targeted bacteria was obtained. This research lays a foundation for further study of the biological functions of the transcription factor LeHB-1 during the development of fruits via the transformation of tomato.
Key words: tomato, specific expression vector pBI121-2A11-HB-1, vector construction, Agrobacterium-mediated genetic transformation system
