Cucumber mosaic virus (CMV) caused huge agricultural impact on Passiflora edulis. However, the interactions between CMV and P. edulis are poorly unknown, which lead to lack of prevention and control measures. In this study, we identified the infection of CMV in P. edulis through modern small RNA sequencing (sRNA-seq) technology combined with traditional electron microscope and polymerase chain reaction (PCR) methods. We also confirmed CMV infection adversely affected or modulated the contents of phytochemicals and further injured the development of P. edulis; inversely, P. edulis modulated its resistance to CMV stress by increasing the levels of secondary metabolites and the activities of antioxidant enzymes components. This is of significant importance to understand the interaction between virus infection and plant host.
黄瓜花叶病毒（CMV）对可食用百香果造成了巨大的农业影响。然而，CMV 和百香果之间的相互作用知之甚少，这导致缺乏预防和控制措施。在这项研究中，我们通过现代小 RNA 测序（sRNA-seq）技术结合传统电子显微镜和聚合酶链反应（PCR）方法，确定了 CMV 在百香果中的感染。我们还证实，CMV 感染会对植物化学物质的含量产生不利影响或调节，从而进一步损害百香果的发育；相反，百香果通过增加次生代谢物的水平和抗氧化酶成分的活性来调节其对 CMV 胁迫的抗性。这对于理解病毒感染与植物宿主之间的相互作用具有重要意义。
