Analyses of the temporal dynamics of fungal communities colonizing the healthy wood tissues of esca leaf-symptomatic and asymptomatic vines.

TL;DR: Diverse fungal assemblages, made up of potentially plant-pathogenic and -protective fungi, colonized non-necrotic tissues of vines that expressed or not foliar esca-symptoms, and no increase in necrosis areas was observed over the one-year period.
Phenotypic Differences Between vacuma and transposa subpopulations of Botrytis cinerea

TL;DR: A significant negative correlation was established between virulence and mycelial growth rate, and the grapevine leaves were significantly more susceptible to B. cinerea than those of tobacco.

Emilie Bruez,Pascal Lecomte,Jacques Grosman,Bruno Doublet,Christophe Bertsch,Florence Fontaine,Adeline Alonso Ugaglia,Pierre-Louis Teissedre,Jean-Pierre Da Costa,Lucia Guerin-Dubrana,Patrice Rey +10 more
TL;DR: The National Grapevine Trunk Disease Survey was conducted in France from 2003 to 2008 to monitor grapevine trunk diseases, eutypa dieback and esca/black dead arm, with great variations amongst regions in the incidence of GTDs.

Grapevine pruning systems and cultivars influence the diversity of wood-colonizing fungi
Renaud Travadon,Pascal Lecomte,Barka Diarra,Daniel P. Lawrence,David Renault,Hernán Ojeda,Patrice Rey,Kendra Baumgartner +7 more
TL;DR: Grapevine wood hosts diverse fungal species, including pathogens that cause grapevine trunk diseases and wood decomposers, with detrimental effects on yields, but greater levels of wood necrosis may be due to the composition of the fungal community rather than to a greater diversity of taxa.

Exploring the Hydraulic Failure Hypothesis of Esca Leaf Symptom Formation
Giovanni Bortolami,Gregory A. Gambetta,Sylvain Delzon,Laurent J. Lamarque,Jérôme Pouzoulet,Eric Badel,Régis Burlett,Guillaume Charrier,Hervé Cochard,Silvina Dayer,Steven Jansen,Andrew J. King,Pascal Lecomte,Frederic Lens,José M. Torres-Ruiz,Chloé E. L. Delmas +15 more
TL;DR: The results demonstrate that symptom development is associated with the disruption of vessel integrity and suggest that symptoms are elicited at a distance from the trunk where fungal infections occur, and open new perspectives on esca symptom expression.
