RNAi-mediated antiviral immune response https://github.com/geneontology/go-ontology/issues/19958 GO:0060150 RNAi-mediated antiviral immunity A post-transcriptional gene silencing pathway mediated by the action of regulatory RNAs that protects against foreign organism invasion by restricting viral replication and dissemination. GO:0009616 viral triggering of virus induced gene silencing virus-induced gene silencing Virus induced gene silencing (VIGS) is used as a technique to control plant gene expression; when used in that context, this does not represent a normal biological process and is outside the scope of GO.
