What is Pierce's Disease?

Pierce's Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

The Xylella fastidiosa Biocontrol Strain EB92-1 Genome Is Very Similar and Syntenic to Pierce's Disease Strains

  • Abstract: Xylella fastidiosa infects a wide range of plant hosts and causes economically serious diseases, including Pierce's disease (PD) of grapevines. X. fastidiosa biocontrol strain EB92-1 is infectious to grapevines but does not cause symptoms. The draft genome of EB92-1 reveals that it may be missing 10 potential pathogenicity effectors.
