a Representative images showing wilt symptoms in the wild-type Desiree and StMKK1 RNAi transgenic lines. W/T represents the number of wilting plants with respect to the total number of infected plants. b Statistical analysis of the amount of bacteria in plant stems showed significantly reduced bacterial colonization in StMKK1 RNAi lines compared with that in Desiree. Two-week-old potato plants were infected by the hydroponic infection method and photographed at 5 dai. The test was repeated three times with similar results. Error bars show the standard deviations from eight replicates. Two-sided t-tests were used to assess significance: **, p < 0.01
