Bacterial chemoattraction towards jasmonate plays a role in the entry of Dickeya dadantii through wounded tissues

Descripción
Jasmonate is a key signalling compound in plant defence that is synthesized in wounded tissues. In this work, we have found that this molecule is also a strong chemoattractant for the phythopathogenic bacteria Dickeya dadantii (ex-Erwinia chysanthemi). Jasmonic acid induced the expression of a subset of bacterial genes possibly involved in virulence/ survival in the plant apoplast and bacterial cells pretreated with jasmonate showed increased virulence in chicory and Saintpaulia leaves. We also showed that tissue wounding induced bacterial spread through the leaf surface. Moreover, the jasmonate-deficient aos1 Arabidopsis thaliana mutant was more resistant to bacterial invasion by D. dadantii than wild-type plants. These results are consistent with the hypothesis that sensing jasmonic acid by this bacterium helps the pathogen to ingress inside plant tissues.
