Summary The filamentous fungus Fusarium graminearum possesses an RNA‐interference (RNAi) pathway that acts as a defence response against virus infections and exogenous double‐stranded (ds) RNA. Fusarium graminearum virus 1 (FgV1), which infects F. graminearum, confers hypovirulence‐associated traits...
