Grapevine leafroll disease, primarily associated with grapevine leafroll-associated virus 3 (GLRaV-3), significantly affects grapevine physiology and productivity.

Grapevine is one of the most important crops worldwide. In a climate change scenario, vineyards face not only abiotic challenges, but also recurrent annual outbreaks of diseases, such as downy mildew and grey mould, caused by the oomycete Plasmopara viticola (PV) and the fungi Botrytis cinerea (BC), respectively.

Black rot, caused by the ascomycete Guignardia bidwellii (anamorph Phyllosticta ampelicida), is an important fungal disease of grapevine (Vitis vinifera L.) and can lead to severe yield losses, particularly under warm and humid conditions.

Grapevine (Vitis vinifera L.) is one of the most widely cultivated fruit crops worldwide and is susceptible to numerous pathogens, including viruses.

Esca is a major grapevine trunk disease caused by a consortium of xylem-colonising and wood-degrading fungi, including Phaeomoniella chlamydospora, Phaeoacremonium minimum and Fomitiporia mediterranea and poses a growing threat to vineyard longevity.

Grapevine (Vitis vinifera L.) is considered to be among the most widely grown and major fruit crops worldwide with high economic importance.

Grapevines are continually wounded throughout their cultivation, particularly during winter pruning.

Plant-pathogen interactions can trigger extensive epigenetic modifications in the host genome.

With the increasing frequency and intensity of extreme weather events, viticulture is expected to face progressively drier and warmer conditions, increasing the need for sustainable adaptation strategies such as the identification of resilient Vitis vinifera L. varieties.
