The sulfated laminarin triggers a stress transcriptome before priming the SA- and ROSdependent defenses during grapevine's induced resistance against Plasmopara viticola

ABSTRACT: Cultivated grapevine (Vitis vinifera) is susceptible to many pathogens which cause significant losses to viticulture worldwide. Chemical control is available, but agro-ecological concerns have raised interest in alternative methods, especially in elicitation of plant immunity by bio-molecules such as Pathogen Associated Molecular Patterns (PAMPs). We have demonstrated that the beta-glucan laminarin (Lam) and its sulfated derivative (PS3) induce a PAMP-triggered immunity in grapevine against downy mildew (Plasmopara viticola). However, if Lam elicits classical grapevine defenses, PS3 triggered grapevine resistance via a poorly understood priming phenomenon. The aim of this study was to discover the mechanism of the PS3-induced resistance. On uninfected grapevine, we first investigated defen
