Small RNAs (sRNAs), including microRNAs (miRNAs) and short interfering RNAs (siRNAs), are non-coding but powerful RNA molecules of 20-30 nucleotides in length. sRNAs play crucial regulatory roles in diverse plant biological processes. Recently, many studies on sRNAs have been reported. We summarize new findings of sRNAs in virus-plant interactions to accelerate the function analysis of sRNAs. The main content of this review article includes three parts: virus-responsive sRNAs, function analysis of sRNAs in virus pathogenicity or host resistance, and some sRNAs-mediated underlying mechanisms in virus-plant interactions. New findings of sRNAs deepen our understanding about sRNAs' roles, which might contribute to the design of novel control measures against plant viruses.
小 RNA（sRNA），包括 microRNA（miRNA）和 small interfering RNA（siRNA），是 20-30 个核苷酸长度的非编码但功能强大的 RNA 分子。sRNA 在多种植物生物学过程中发挥着至关重要的调节作用。最近，已有许多关于 sRNA 的研究报告。我们总结了 sRNA 在病毒-植物相互作用中的新发现，以加速 sRNA 功能分析。这篇综述文章的主要内容包括三个部分：病毒响应的 sRNA、sRNA 在病毒致病性或宿主抗性中的功能分析，以及病毒-植物相互作用中的一些 sRNA 介导的潜在机制。sRNA 的新发现加深了我们对 sRNA 作用的理解，这可能有助于设计针对植物病毒的新型控制措施。
