Abstract Maintaining wine production under global warming partly relies on optimizing the choice of plant material for a given viticultural region and developing drought-resistant cultivars. However, progress in these directions is hampered by the la

Publikováno v: IVES Technical Reviews (2023)

Global viticulture has seen decreases in fruit yield and vine longevity over the past two decades. Our understanding of the underlying causes is limited by the complex interactions among the different factors involved and the technical challenges tha

International audience; In the context of climate change, plant mortality is increasing worldwide in both natural and agroecosystems. However, our understanding of the underlying causes is limited by the complex interactions between abiotic and bioti

Hydraulic failure has been extensively studied during drought-induced plant dieback, but its role in plant-pathogen interactions is under debate. During esca, a grapevine (Vitis vinifera) disease, symptomatic leaves are prone to irreversible hydrauli
