摘要
RNA干扰是多种生物体内由双链RNA介导的同源mRNA降解现象,是植物体内天然的抗病毒机制。然而病毒在长期进化过程中也获得了通过编码沉默抑制蛋白来对抗植物体RNAi系统的能力。本文对RNA干扰过程、病毒编码的沉默抑制蛋白及利用干扰技术进行抗病毒基因工程研究进行简要综述。
RNA interference is a phenomenon of homologous RNA digestion mediated by double-stranded RNA, which is a natural defense system against virus in plants, However, against this defense system of plants, viruses obtained the ability evolutionally to code suppressors of silencing, This paper reviews the advance of RNAi mechanism research, suppressors of silencing coded by virus, and application of RNAi in plant gene engineering for anti-virus,
