Plants' response to pathogens is highly complex and involves changes at different levels, such as activation or repression of a vast array of genes. Recently, many studies have demonstrated that many RNAs, especially small RNAs (sRNAs), are involved in genetic expression and reprogramming affecting plant-pathogen interactions. The sRNAs, including short interfering RNAs and microRNAs, are noncoding RNA with 18-30 nucleotides, and are recognized as key genetic and epigenetic regulators. In this review, we summarize the new findings about defence-related sRNAs in the response to pathogens and our current understanding of their effects on plant-pathogen interactions. The main content of this review article includes the roles of sRNAs in plant-pathogen interactions, cross-kingdom sRNA trafficking between host and pathogen, and the application of RNA-based fungicides for plant disease control.
植物对病原体的反应非常复杂，涉及不同层面的变化，例如大量基因的激活或抑制。最近，许多研究表明，许多 RNA，特别是小 RNA（sRNA），参与影响植物-病原体相互作用的基因表达和重编程。这些 sRNA，包括短干扰 RNA 和 microRNA，是非编码 RNA，长度为 18-30 个核苷酸，被认为是关键的遗传和表观遗传调节剂。在这篇综述中，我们总结了关于防御相关 sRNA 在应对病原体中的新发现，并介绍了我们目前对其影响植物-病原体相互作用的理解。这篇综述文章的主要内容包括 sRNA 在植物-病原体相互作用中的作用、宿主和病原体之间的跨领域 sRNA 运输，以及基于 RNA 的杀菌剂在植物病害控制中的应用。
