FIGURE 4

Interbacterial competition assay with P. phymatum (dsRed T6SS+) and T6SS mutants as attackers. The graphs show the recovered colony forming units (CFU) of the target bacteria: P. diazotrophica gfp (A), P. sabiae (B), and P. mimosarum gfp (C). The dots represent the average of three independent experiments (+/– SEM). None: no attacker strain. Two-tailed t-test. (A) p = 0.0092 in the survival of targets against P. phymatum as attacker, p = 0.0445 against Pphy::tssB-3 and p = 0.6119 against Pphy::tssI-b. (B) p = 0.028 in the survival of the target against P. phymatum, p = 0.0282 against Pphy::tssB-3 and p = 0.0286 against Pphy::tssI-b. (C) p = 0.0139 in the survival of the target against P. phymatum, p = 0.1161 against Pphy::tssB-3 and p = 0.037 against Pphy::tssI-b.
