R. solanacearum strains showed differential virulence in in vitro potato infection system. a Representative picture of inoculated plants at 4 dpi. “W/T” indicates the number of wilting plants with respect to the total of infected plants. b The bacterial content in potato stems measured at 4 dpi. This experiment was repeated three times with similar results. **P < 0.001 (Student’s t test) comparing with UW551 strain
