摘要 植物小RNA介导的RNA干扰在植物响应病原菌侵染的免疫反应中发挥重要作用。研究发现,小RNA(sRNAs)可以跨界转运,参与植物免疫和病原菌的致病过程,这种突破物种界限,转运到寄主或微生物体内沉默靶基因的现象,称为跨界RNA干扰(Cross-kingdom RNAi)。跨界RNA干扰技术的应用为当前植物保护和抗病育种提供了新的方向。文章综述了跨界sRNAs的合成路径、转运机制及其在植物免疫和病原菌毒力方面的研究进展,以期为跨界RNA干扰技术在植物病害防控领域的应用提供参考信息。 RNA interference mediated by small RNAs plays an important role in plant immune response to pathogen infection.Researches have shown that small RNAs can be transported to silent target genes across borders and participate in plant immunity and pathogen′s pathogenic process,which is called Cross-kingdom RNAi.The application of Cross-kingdom RNAi technology provides a new direction for plant protection and disease resistance breeding.In this paper,the synthesis pathway,the action mechanism,the transport mechanism,and the research progress in plant immunity and pathogen virulence of Cross-kingdom small RNA are reviewed in order to provide reference information for the application of Cross-kingdom RNAi technology in plant disease prevention and control.
