Growth Parameter Components of Adaptive Specificity during Experimental Evolution of the UVR-Inducible Mutator Pseudomonas cichorii 302959
Figure 8
Average percent reduction in lag time.
Lag time of UVR lineage population samples, UVR lineage isolates, and non-UVR lineage isolates after (A) 250 and (B) 500 generations of experimental evolution was measured under non-UVR (open bars) and UVR (shaded bars) conditions. Values represent the average percent improvement compared to the P. cichorii 302959 ancestor doubling times of 10.27±0.32 hrs and 10.47±0.26 hrs under non-UVR and UVR conditions, respectively. Error bars represent standard error of the mean. n = 8 for UVR lineage population samples and non-UVR lineage isolates but n = 16 for UVR lineage isolates. Values are significant by two-tailed independent t-test (α = 0.05) where indicated (* P<0.05, ** P<0.01, *** P<0.001). P-paired values correspond to two-tailed paired t-tests (α = 0.05) between non-UVR and UVR conditions.
