L’activation des réponses immunitaires des plantes repose sur la reconnaissance de motifs moléculaires associés aux pathogènes (aussi appelés PAMP) par des récepteurs de l’immunité, également nommés PRR (pattern recognition receptors). La chitine, principal composant de la paroi des champignons, est un PAMP bien caractérisé qui induit des réponses de défense aussi bien chez les mammifères que chez les plantes.La première partie de cette étude met en évidence que deux chito-oligosaccharides, la chitine et le chitosan, agissent comme des PAMP chez la vigne (Vitis vinifera) puisqu’ils induisent des évènements précoces de signalisation, l’expression de gènes de défense et une résistance contre des agents pathogènes. Ces résultats suggèrent que ...
