Abstract Feruloyl esterase (ferulic acid esterase, FAE) is an essential component of many biological processes in both eukaryotes and prokaryotes. This research aimed to investigate the role FAE its regulation mechanism plant immunity. We identified a secreted feruloyl VdFAE from hemibiotrophic pathogen Verticillium dahliae . acted as important virulence factor during V infection, triggered defence responses, including cell death Nicotiana benthamiana Deletion led decrease degradation ethyl ferulate. interacted with Gossypium hirsutum protein dihydroflavanol 4‐reductase (GhDFR), positive regulator innate immunity, promoted GhDFR. Furthermore, silencing GhDFR reduced resistance cotton plants against The results suggested fungal strategy which secretes interact host DFR interfere thereby promoting infection.
