摘要:
该试验提出了一种简单且快速构建番茄中人工miRNA表达载体的方法，以包含miR319a前体骨架的质粒pRS300为模板，以重叠PCR技术来扩增miR1917的前体。miR1917的靶基因是LeCTR1，是乙烯反应中的一种负调控因子。含有miR1917的重组前体成功地转化到表达载体pGreen0029-35s中，通过植物根癌农杆菌C58介导的叶盘法成功获得了转基因植株。此种方法可为番茄中miRNA的作用机理研究提供一定的理论基础。
Abstract:
A microRNA-baesd method for easy and rapid construction of tomato miRNA vector was described.The plasmid PRS300 which contained the miR319a precursor was used as the temple，the overlapping PCR amplification for the miR1917 whose target gene was LeCTR1 which were key negative regulators of ethylene responses was processed，and the reconstructed precursor was successfully transformed to the expression vector pGreen0029-35s.The transgenic plants were successfully obtained by the leaf disc method mediated by Agrobacterium tumefaciens C58.This method could provide a theoretical basis for the miRNA mechanisms of action research in tomato.
