Pathogenicity assays of Ralstonia solanacearum triple gala mutants on Arabidopsis thaliana and Lycopersicon esculentum (tomato). Kaplan–Meier survival analysis of A. thaliana (a, b, c) and tomato (d, e) plants inoculated with R. solanacearum mutants. Genotypes of the tested strains are the following: GMI1000, wild-type; GRS536, gala2, 3, 7; GRS537, gala2, 3, 6; GRS538, gala3, 6, 7; GRS539, gala2, 6, 7; GRS460, gala2, 3, 6, 7. Each strain was inoculated on 16 A. thaliana plants (a, b, c) and 24 tomato plants (d, e). P-values from Gehan–Breslow–Wilcoxon tests are associated with each graph. Yellow boxes indicate a P-value of <0.05. These experiments were performed three times with similar results.
