The Burkholderia cenocepacia T6SS‐1 plays a role in bacterial competition. (a) Recovery of viable P. putida, E. coli SM10(λpir) and E. coli CC118(λpir) (in CFU/ml) “prey” strains following coculture with the indicated B. cenocepacia H111 “attacker” strains for 4 hr at 30°C. (b) Comparison of recovery of E. coli SM10(λpir) prey following coculture with B. cenocepacia H111 WT or ΔtssM mutant attacker strains carrying complementation or control plasmids pBBR1‐tssM(+) (“ptssM”) and pBBR1MCS (“pBBR1”), respectively. n ≥3 and error bars indicate SD
