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.

Phylogeny of Replication Initiator Protein TrfA Reveals a Highly Divergent Clade of Incompatibility Group P1 Plasmids

  • Author(s): Lee, MW; Stenger, DC;
  • Abstract: Incompatibility group P1 (IncP-1) plasmid diversity was evaluated based on replication initiator protein (TrfA) phylogeny. A new and highly divergent clade was identified. Replication assays indicated that TrfA of recently discovered IncP-1 plasmids from Xylella fastidiosa and Verminephrobacter eiseniae initiated plasmid replication using cognate or heterologous origins of replication.
