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.

Genetic differences between two strains of Xylella fastidiosa revealed by suppression subtractive hybridization

  • Author(s): Gabriel, Dean; Harakava, R.;
  • Abstract: Suppression subtractive hybridization was used to rapidly identify IS gene differences between a citrus variegated chlorosis (CVC) strain and a Pierces disease of grape (PD) strain of Xylella fastidiosa. The results were validated as being highly representative of actual differences by comparison of the completely sequenced genome of a CVC strain with that of a PD strain.
