Summary The recognition of pathogen effectors by plant immune receptors leads to the activation of immune responses that often include a hypersensitive response ( HR ): rapid and localized host cell death surrounding the site of attempted pathogen ingress. We have demonstrated previously that the recognition of the V erticillium dahliae effector protein A ve1 by the tomato immune receptor V e1 triggers an HR in tomato and tobacco. Furthermore, we have demonstrated that tomato V e1 provides V erticillium resistance in A rabidopsis upon A ve1 recognition. In this study, we investigated whether the co‐expression of V e1 and A ve1 in A rabidopsis results in an HR , which could facilitate a forward genetics screen. Surprisingly, we found that the co‐expression of V e1 and A ve1 does not induce an HR in A rabidopsis. These results suggest that an HR may occur as a consequence of V e1/ A ve1‐induced immune signalling in tomato and tobacco, but is not absolutely required for V erticillium resistance.
