Interpretive Summary: Bacterial stem blight on alfalfa is widespread in the central and western United States and occasionally occurs in eastern states. It has also been reported in Australia and Europe, and has recently been reported in western Iran; however, little is known about the pathogen causing this disease. The complete genome sequence of the pathogen was obtained and compared with genomes of closely related bacteria. Approximately 60 genes were unique to the alfalfa pathogen, including several predicted to be involved in causing disease. The alfalfa pathogen is most closely related to the bacterium causing bacterial blast of pear. Availability of this genome sequence will enable studies on the molecular basis for adaptation to alfalfa.

Technical Abstract: We report the annotated draft genome of Pseudomonas syringae pv. syringae strain ALF3, isolated in Wyoming, USA. Comparison of this genome sequence with those of closely related strains of P. syringae pv. syringae adapted to other hosts will facilitate research into interactions between this pathogen and alfalfa.
