description

National audience; Gray mold (Botrytis cinerea) causes significant annual yield and quality losses to viticulture. Comparison of transcriptomes of compatible and non-compatible interaction with Vitis vinifera cv Marselan – on harvesting stage berries or véraison stage berries, respectively – suggest the jasmonic acid pathway is activated in the former, while the salicylic acid pathway is more pronounced in the latter. In addition, in the non-compatible case, reactive oxygen species accumulation seems to be both early and strong, and some genes involved in cell-wall reinforcement are up-regulated.
