Effects of inoculation with T6–4 isolate on the tomato growth. Shoot length (A), length of the longest leaf (B), shoot fresh weight (C) and dry weight (D) were measured 30 days after bacterial inoculation. Control plants received an equal volume of distilled water. Values are means ± SE (n = 20). The asterisks indicate statistically significant differences according to independent t-test between the bacterium-inoculated group and control group (*P < 0.05, **P < 0.01, ***P < 0.001). ns, not significant
