ABSTRACT Here we announce the complete genome sequence of the symbiotic and nitrogen-fixing bacterium Sinorhizobium fredii USDA257. The genome shares a high degree of sequence similarity with the closely related broad-host-range strains S. fredii NGR234 and HH103. Most strikingly, the USDA257 genome encodes a wealth of secretory systems.
