Complete genome sequence of RSSC phylotype-I strains infecting different host plants

Ralstonia solanacearum species complex (RSSC) is classified into four phylotypes. Mostly phylotype-I strains and some phylotype-IV strains have been isolated in Japan. While Japanese phylotype-IV strains infect only a potato, phylotype-I strains show a broad host range. Repertoires of type III effectors (T3Es) mainly determine the RSSC host range. The first step for investigating RSSC host specificity could be the comparison of T3Es among phylotype-I strains. We have determined the complete genome sequences of phylotype-I strains in this study and extracted repertoires of T3Es. We will compare T3Es and find differences to determine the specific factors for host specificity.
