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...
Detection and visualization of an exopolysaccharide produced by Xylella fastidiosa in vitro and in planta
Many phytopathogenic bacteria, such as Ralstonia solanacearum, Pantoea stewartii, and Xanthomonas campestris, produce exopolysaccharides (EPSs) that aid in virulence, colonization, and survival. EP...
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 ...
Xylella fastidiosa infection and ethylene exposure result in xylem and water movement disruption in grapevine shoots
It is conventionally thought that multiplication of the xylem-limited bacterium Xylella fastidiosa (Xf) within xylem vessels is the sole factor responsible for the blockage of water movement in gra...
