Previously, we have reported the ability of thiamine (vitamin B1) to induce resistance against Plasmopara viticola in a susceptible grapevine cv. Chardonnay. However, mechanisms underlying vitamins, especially, thiamine-induced disease resistance in grapevine are still largely unknown. Here, we assessed whether thiamine could modulate phenylpropanoid(More)
Grapevine (Vitis vinifera) is susceptible to a variety of pathogenic fungi that affect yield and wine quality. Their control is generally achieved by widespread application of fungicides in the vineyards. The economic costs and negative environmental impact associated with these applications has led to a quest for alternative strategies, focusing on(More)
RNA silencing is a natural defence mechanism against viruses in plants, and transgenes expressing viral RNA-derived sequences were previously shown to confer silencing-based enhanced resistance against the cognate virus in several species. However, RNA silencing was shown to dysfunction at low temperatures in several species, questioning the relevance of(More)
