In planta growth of Ralstonia pseudosolanacearum after stem injection of strains GMI1000, GMI1000 ripAX2::pCZ367 and GMI1000 ripAX2::pCZ367::ripAX2 on MM738 and AG91‐25 eggplants, just after injection (A) and 3 days after injection (B). Each strain was inoculated by injection into the stem [10⁶ colony‐forming units (CFU)/mL, 10 µL per plant]. Each point corresponds to the value obtained from a single plant. The three biological replicates are shown in different colours. Statistical analyses for grouping were performed by Kruskal–Wallis test with α = 0.05. No statistical differences were found just after injection by the different strains in MM738 and AG91‐25. No statistical difference was found 3 days after injection in MM738.
