摘要
目前RNA病毒的反向遗传操作的发展非常迅速,已经在新城疫病毒得到应用。本文简述了新城疫病毒感染性分子克隆构建的基本机理,以及采用反向遗传操作技术利用新城疫病毒制备标记疫苗、研究病毒基因的结构与功能、制备表达外源基因的重组病毒等方面的研究进展。
The current techniqu e of genetic manipulat ion of RNA virus by reverse genetic system have developed quickly,it has been u sed in New Castle Disease Virus(NDV),this review lustrated the basic techniqu e to construct NDV from cloned cDNA,and development of this technique to study virus gene structure to functioin,construct marker vaccine,construct chimeric virus expressing exologus genes.This review summarized all the applicatioin an d development of reverse genetic system used in NDV.
