One or the other: under drought, grapevines do not express esca leaf symptoms

Global viticulture has seen decreases in fruit yield and vine longevity over the past two decades. Our understanding of underlying causes is limited by complex interactions among different factors involved technical challenges that limit investigations these interactions. In Bortolami et al. (2021a) we investigated interaction between main drivers grapevine decline, drought vascular disease (esca), monitoring esca leaf symptom development physiology Sauvignon blanc during both stresses. We found conditions inhibited revealing key role plant water status pathogenesis opening new perspectives into use management context climate change.
