Fig. 1: P. aeruginosa (Pa) is more resistant to T6SS from A. baylyi (Ab) ADP1 and V. cholerae (Vc) 2740-80 than E. coli (Ec).

CFU counts showing the survival of P. aeruginosa when competed against A. baylyi ADP1 (Ab) (A) and V. cholerae 2740-80 (Vc) (B) strains that have or do not have an active H1-, H2- and H3-T6SS, in a 10:1 attacker:prey ratio where P. aeruginosa is the prey. C CFU counts showing the survival of E. coli (Ec) when competed against A. baylyi and V. cholerae in 10:1 and 1:1 attacker:prey ratios where E. coli is the prey, when A. baylyi and V. cholerae have or do not have a fully functional T6SS (ΔtssM) and when they do not carry any known active T6SS effectors (effector deletions for A. baylyi and effector-inactivating mutations for V. cholerae). Source data are provided as a Source Data file. The bars indicate the mean across three independent biological replicates, the error bars indicate the standard deviation. Each biological replicate represents one data point. Data were analyzed with ordinary two-way ANOVA and Sidak’s correction for multiple comparisons. Statistically significant adjusted p-values are indicated with asterisks and are (left to right) 0.0006*** and <0.0001****. ns: non-significant. The datapoints are colored according to the Pa strain used.
