Updated project metadata. Botrytis cinerea is the causing agent of grey mould on hundreds of plants cultivated in fields, tunnels and greenhouses worldwide. Considering the central role of secretion in the necrotrophic interaction between the fungus and its host plants, non conventional secre-tion was explored through the search and characterisation of extracellular vesicles. In or-der to reveal the protein composition of these vesicles, a proteomic analysis was chosen.
