Abstract
The pathogenicity and host range of Pseudomonas syringae strains are controlled in part by the hrp gene cluster. At least 24 genes organized as 7 transcriptional units have been identified within the cluster in several P. syringae strains [1, 2]. In some strains, accessory genes, such as hrmA, are associated with the hrp cluster [3]. The principle function of the cluster appears to be the production and secretion of a proteinaceous plant response elicitor, Harpinpss, that is responsible for the Hrp phenotype [4]. This protein factor apparently controls the pathogenicity of P. syringae strains in susceptible hosts and the elicitation of defense responses associated with the hypersensitive response in resistant hosts.
