pubmed:abstractText	We had previously isolated and characterized syringolin A, one of the molecular determinants secreted by Pseudomonas syringae pv syringae that is perceived by nonhost plant species such as rice. Here, we show that syringolin A is recognized by wheat and that it induces the accumulation of gene transcripts and increases protection against powdery mildew when applied before inoculation. Moreover, syringolin A essentially eradicates powdery mildew from infected wheat if applied after inoculation. This curative effect is accompanied by the induction of cell death and the reactivation of pathogenesis-related genes whose transcript levels initially accumulate after powdery mildew inoculation but then decline during the later course of infection. Because syringolin A has no fungicidal activity against a variety of fungi and its action on wheat cannot be mimicked by the fungicide cyprodinil, syringolin A is hypothesized to counteract the suppression of host defense reactions imposed by the pathogen on the colonized cells.
