Relationship between the xylem anatomy of grapevine rootstocks and their susceptibility to Phaecremonium minimum and Phaeomoniella chlamydospore

Fungal grapevine trunk diseases (GTDs) are some of the most pressing threats to grape production worldwide. While these diseases are associated with several fungal pathogens, Phaeomoniella chlamydospora and Phaeoacremonium minimum are important contributors to esca and Petri diseases. Recent researc...
