Ralstonia solanacearum, previously named Pseudomonas solanacearum and Burkholderia solanacearum, is a soil-borne gramnegative bacterium that causes bacterial wilt disease on more than 200 plant species from 50 botanical families, including important crops such as potato, tomato, eggplant, pepper, tobacco and banana. R. solanacearum is considered a species complex-a heterogeneous group of related but genetically distinct strains. This bacterium infects plants through root wounds or at sites of secondary root emergence, then colonizes the xylem vessels and spreads rapidly to aerial parts of the plant through the vascular system. In xylem vessels, the bacterial population can multiply extensively and rapidly reach very high levels (>1010 cells/cm of stem in tomato).
