Extended Data Fig. 8: Head-to-head weapon competitions between short and long-range weapon users at the colony edge.
From: The evolution of short- and long-range weapons for bacterial competition
Quantification of direct weapon colony competition outcomes at the colony edge by sampling, plating and counting colony forming units. Competitive advantage assesses the fold change in the attacker strain compared to its competitor from the beginning to end of the competition. Values above 1 (10°, dashed line) indicate an advantage for CDI, while values below 1 (that is 10−2, 10−4) indicate an advantage for tailocins. Horizontal lines indicate the mean from biological replicates (n = 8). Top brackets indicate a significant difference between the initial ratios (two-sided Welch’s t-test, p < 0.05, Benjamini-Hochberg correction for multiple testing, see Supplementary Table 5 for exact p values). Stars indicate a competitive advantage significantly different from 0 (one-sided Welch’s t-test, p < 0.05, Benjamini-Hochberg correction for multiple testing, see Supplementary Table 5 for exact p values). Competitions were inoculated with different initial densities (mean inoculum density 2.3 * 105, 106 CFU/µL). The genotype of the CDI using, tailocin susceptible strain (blue) is ΔR2ΔwbpL. The genotype of the tailocin using, CDI susceptible strain is ΔwapRΔCDI.
