Abstract: Production of phytotoxin coronatine (COR) in defined hrp/hrc mutants of Pseudomonas syringae pv tomato DC3000 has been analyzed. The goal was to study the coordinated regulation, if any existed, of different systems necessary for virulence and pathogenicity. Results show it is likely that the hrp/hrc secretion system is not necessary for COR production. Mutations in the system however may have regulatory effects on production of virulence factors of the COR type
