Abstract: 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.

Key words: Cross-kingdom sRNAs, Small RNA interference, Pathogen, Plant immune
