Abstract: Plant immunity pathways Plants successfully defend themselves against most fungal attacks, but the underlying mechanisms involved remain poorly understood. A study of Arabidopsis plants exposed to powdery mildew fungi has identified one component of the immune response as a ternary complex consisting a syntaxin protein called PEN1, the SNARE protein SNAP33 and two vesicle-associated membrane proteins, VAMP721 and VAMP722. Unexpectedly, the latter have a second functionally redundant role in a default secretory pathway. It is possible that an ancient secretory pathway involving these VAMP proteins was co-opted to form part of the secretory plant immune response.
