摘要 以马铃薯Y病毒(Potato virus Y,PVY)为基础构建了含PVY CP基因3’端253bp反向重复片段的双链RNA(dsRNA)原核表达载体,并转化大肠杆菌HT115(DE3),经IPTG诱导产生dsRNA,用LiCl沉淀法提取,获得了高质量的dsRNA。 A dsRNA prokaryotic expression vector with 253bp inverted repeat fragment was constructed based on the CP gene of potato virus Y. The vector was transformed to E. coli HT115 (DE3)and induced by IPTG to express dsRNA. Finally, a dsRNA with high quality was extracted by LiCl precipitation method.
