The role of lipopolysaccharide in virulence and host specificity of Xylella fastidiosa

This project focuses on the lipopolysaccharide (LPS) component of the outer membrane of Xylella fastidiosa (Xf). In particular, we are investigating if the O-antigen portion of this molecule contri...

Xylella fastidiosa requires Type II-secreted endoglucanases for virulence in grapevine

The ability of Xylella fastidiosa (Xf), the causal agent of Pierce’s Disease in grapevine, to systemically colonize the xylem directly correlates with symptom development. Xf facilitates its coloni...

Xylella fastidiosa utilizes a beta 1,4 endoglucanase to modulate exopolysaccharide production and the dynamics of biofilm development

Xylella fastidiosa (Xf), a gram-negative bacterium that causes numerous severe diseases in economically important crops, resides in the host xylem and in the mouthparts of its insect vectors where ...
