gala2, 3, 6, 7 mutant (strain GRS460, triangles) phenocopies the septuple gala mutant (strain GRS447, squares) on Arabidopsis thaliana and Lycopersicon esculentum (tomato) but not on Solanum melongena (eggplant). Kaplan–Meier survival analysis of A. thaliana (a), tomato (b) and eggplant (c) plants inoculated with Ralstonia solanacearum. GMI1000, wild-type, circles. Each strain was inoculated on 16 A. thaliana plants (a), 24 tomato plants (b) and 20 eggplant plants (c). Correspondence between strains and color code is conserved in the three graphs. 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 at three times with similar results.
