摘要: RNA干扰(RNA interference。RNAi)是利用双链RNA(dsRNA)特异性地降解相应序列的mRNA,从而特异性地阻断相应基因地表达.在过去10年中,RNA干扰及相关沉默反应的机制研究取得了重大进展, RNAi也发展成为一种强有力的实验工具,用来控制目的基因的表达以获取预期的生物表型。本文详细综述了近年来RNA干扰机制方面的研究进展及RNA干扰在植物中的应用进展。

Abstract: Introduction of double—stranded RNA(dsRNA)into cells can induce specific mRNA degradation,This process is called RNA interference(RNAi).During the past 10 years, tremendous progress has been made in revealing the underlying mechanism of RNAi and related silencing responses. RNAi has become a powerful research tool in regulating the expression of target genes for expected or desirable phenotypes. In this article,the mechanism of RNAi has been described and summarized,and the application of RANi in plant functional genomics has also been reviewed。
