Alfano, J. R., Charkowski, A. O., Deng, W., Badel, J. L., Petnicki-Ocwieja, T., van Dijk, K., & Collmer, A. (2000). The Pseudomonas syringae Hrp pathogenicity island has a tripartite mosaic structure composed of a cluster of type III secretion genes bounded by exchangeable effector and conserved effector loci that contribute to parasitic fitness and pathogenicity in plants.
