Impairment of Grapevine Xylem Function by <em>Phaeomoniella chlamydospora</em> Infection Is Due to More than Physical Blockage of Vessels with 'Goo'

| Summary: | Phaeomoniella chlamydospora is a vascular pathogen that colonises the woody xylem tissues of the grapevine.
It is associated with the grapevine trunk diseases, esca and Petri disease. Infection is usually accompanied by
a dark tarry substance, commonly refered to as ‘black goo’, in some of the xylem vessels. Examination of field grown
Verdelho demonstrated that infection reduced xylem function by 16% for each 1% increase in ‘goo’-blocked vessels,
indicating that vessel blockage is not solely responsible for loss of xylem function. |
