Abstract: Bacterial wilt, caused by Ralstonia solanacearum, is one of the most devastating plant diseases worldwide. As a species complex, R. solanacearum strains are highly variable and adaptable as attested by worldwide distribution and a wide and expanding host range. A new phylotype classification scheme was proposed by Fegan and Prior to distinguish the genetic diversity within the R. solanacearum species complex. High genome complexity and plasticity of R. solanacearum is reflected by its great adaptation potential to different hosts and environments. This review includes recent advances in research of genetic diversity and pathogenome of R. solanacearm species complex.

Key words: Ralstonia solanacearum , genetic diversity , phylotype classification scheme , pathogenome
