| Outline of Final Research Achievements |
Ralstonia solanacearum is a causative agent of lethal bacterial wilt more than 200 species in 50 botanical families, including economically important crops. R. solanacearum is easily spread via contaminated irrigation water and can survive for many years in the soil.
Recently, there are some reports of host behavioral change caused by lysogenic phage infection. In the case of R. solanacearum, we reported a filamentous phage RSS1 infection increase the host pathogenicity. So we tried to research host pathogenicity change according to phage infection stage, lysogenic cycle and active propagate stage.
And we also tried to find the integration/induction conditions of RSS1 phage. We succeeded to detect inducted RSS1 phage under freeze-thaw condition and RSL1 infected condition.
