Cell Wall-Degrading Enzymes Enlarge the Pore Size of Intervessel Pit Membranes in Healthy and Xylella fastidiosa-Infected Grapevines
The pit membrane (PM) is a primary cell wall barrier that separates adjacent xylem water conduits, limiting the spread of xylem-localized pathogens and air embolisms from one conduit to the next. T...
Characterization of the Xylella fastidiosa PD1671 Gene Encoding Degenerate c-di-GMP GGDEF/EAL Domains, and Its Role in the Development of Pierce's Disease
Xylella fastidiosa is an important phytopathogenic bacterium that causes many serious plant diseases including Pierce's disease of grapevines. X. fastidiosa is thought to induce disease by colonizi...
In vitro Determination of Extracellular Proteins from Xylella fastidiosa
The phytopathogen Xylella fastidiosa causes economic losses in important agricultural crops. Xylem vessel occlusion caused by biofilm formation is the major mechanism underlying the pathogenicity o...
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 ...
Transcriptome profiling of two olive cultivars in response to infection by the CoDiRO strain of Xylella fastidiosa subsp pauca
The recent Xylella fastidiosa subsp. pauca (Xfp) outbreak in olive (Olea europaea) groves in southern Italy is causing a destructive disease denoted Olive Quick Decline Syndrome (OQDS). Field obser...
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/...
