Polysaccharide Compositions of Intervessel Pit Membranes Contribute to Pierce's Disease Resistance of Grapevines
Symptom development of Pierce's disease (PD) in grapevine (Vitis vinifera) depends largely on the ability of the bacterium Xylella fastidiosa to use cell wall-degrading enzymes (CWDEs) to break up ...
The effects of Pierce's disease on leaf and petiole hydraulic conductance in Vitis vinifera cv. Chardonnay
In this study, we test the hypothesis that the symptoms of Pierce's Disease (PD) result from the occlusion of xylem conduits by the bacteria Xylella fastidiosa (Xf ). Four treatments were imposed o...
Vascular Occlusions in Grapevines with Pierce's Disease Make Disease Symptom Development Worse
Vascular occlusions are common structural modifications made by many plant species in response to pathogen infection. However, the functional role(s) of occlusions in host plant disease resistance/...
Xylem structure of four grape varieties and 12 alternative hosts to the xylem-limited bacterium Xylella fastidious
The bacterium Xylella fastidiosa (Xf), responsible for Pierce's disease (PD) of grapevine, colonizes the xylem conduits of vines, ultimately killing the plant. However, Vitis vinifera grapevine var...
