【摘要】 为利用转基因技术来探索新的蚊媒疾病防治方法 ,将登革病毒前膜蛋白基因prM重组入以转座子piggyBac因子为基础的载体 ,构建了昆虫转基因载体pB[PUBnls_EGFP_prM],在辅助质粒的作用下共同转染白纹伊蚊AedesalbopictusC6 36细胞。PCR和Southernblot证明构建的转基因载体可以将EGFP_prM基因整合入蚊虫基因组中。验证了转座子piggyBac因子、启动子polyubiquitin可以在白纹伊蚊中发挥功能 ,为进一步构建不传播登革病毒的转基因白纹伊蚊奠定了基础更多还原

【Abstract】 To explore a new method to control arthropod-borne diseases, prM gene from dengue virus was inserted into a transposon piggyBac based plasmid and an insect transgenic vector pB[PUBnls-EGFP-prM] was constructed. The vector was used to transfect Aedes albopictus C6/36 cell with a helper plasmid. PCR and Southern blot tests showed that EGFP-prM gene had integrated into C6/36 cell genome. The results indicate that transposon piggyBac element is functional in Ae. albopictus and should be useful in further constructing dengue-refractory transgenic Ae. albopictus.更多还原
