Multiple pathways under Gac/Rsm control contribute to P. aeruginosa defense against antagonism.

(A) Transposon library sequencing-based comparison of the fitness contribution of individual P. aeruginosa genes during growth competition with wild-type B. thai versus B. thai ∆T6S. Genes under Gac/Rsm control (blue) and those encoding core Gac/Rsm regulatory factors (purple, labeled) are indicated. (B) Overview of the Gac/Rsm pathway (SD, Shine–Dalgarno). The rsmY and rsmZ genes encode small RNA molecules that sequester the translational regulator RsmA. Hybrid sensor kinase PA1611 is here renamed RetS-regulating sensor kinase A (RskA). (C) Left: P. aeruginosa gene clusters hit (greater than threefold in replicate screens; Figure 1—source data 1) in this study. Numbers below genes indicate transposon insertion ratio (B. thai ∆T6S/wild-type) for screen in (A) followed by the replicate screen (Figure 1—figure supplement 1); light toned genes were hit in only one replicate. Asterisk indicates genes for which insertion was undetected in libraries obtained from B. thai wild-type competition. Right: zoom-in of boxed region of (A) with genes colored corresponding to clusters at left. (D, E) Recovery of P. aeruginosa cells with the indicated genotypes following growth competition against B. thai wild-type (D) or ∆T6S (E). For interbacterial competition assays, the mean ± SD of biological duplicates and associated technical duplicates is shown: *p<0.05 using unpaired two-tailed Student’s t-test.

(B) Transposon library sequencing-based comparison of the fitness contribution of individual P. aeruginosa genes during growth competition with wild-type B. thai versus B. thai ∆T6S. Genes under Gac/Rsm control (blue) and those encoding core Gac/Rsm regulatory factors (purple, labeled) are indicated. This experiment is a biological replicate of that in Figure 1A. (C) P. aeruginosa gene clusters hit (Figure 1—source data 1) in this study. (D) Zoom-in of boxed region of (B) with genes colored corresponding to clusters at left.

Arc pathways can provide toxin-specific antagonism defense that eclipses that of other cellular factors.

(A) Recovery of B. thai cells following growth competition against a relative abundance of P. aeruginosa containing the indicated gene deletions, colored according to Figure 1C. (B) Relative survival of P. aeruginosa Arc1-3-inactivated mutants following growth in competition with an excess of the indicated B. thai strains (mutant CFU/parental CFU × 100 for each B. thai competitor). The loss of ColA or Tle3 activity in B. thai increases the relative survival of P. aeruginosa lacking Arc2 or Arc3 activity, respectively. (C, D) Transposon library sequencing-based comparison of the fitness contribution of individual P. aeruginosa genes during growth competition with wild-type B. thai versus B. thai lacking Tle3 (C) or ColA (D) activity, colored according to Figure 1C. Values in parentheses correspond to the number of genes hit (greater than threefold change in transposon insertion frequency) within each cluster compared to the number within each cluster hit in the initial screens (B. thai wild-type versus B. thai ∆T6S) followed by the average transposon insertion frequency ratio (B. thai mutant/B. thai wild-type) of the genes in the depicted screen. (E) Fitness contribution of each P. aeruginosa Arc pathway and the H1-T6SS to defense against Tle3 versus ColA. For interbacterial competition assays, the mean ± SD of biological duplicates and two technical replicates is shown: *p<0.05 using unpaired two-tailed Student’s t-test.
