Here, we report the genome sequence of Ralstonia pseudosolanacearum (R. solanacearum phylotype I) strain SL1931 (KACC10711), isolated from pepper (Capsicum annuum L.) stems; R. solanacearum is the causal pathogen of bacterial wilt. Strain SL1931 had a different type III effector profile than that of the reference genome strain GMI1000.
