Fig. 4: Genomic deletions and their effects on strain fitness.

a Initial and final deletion sizes in the left and right chromosome arms. Dark gray regions represent deletions in the left and right chromosome arms of ancestral strains, while regions in light gray represent new deletions in evolved strains. Sequenced strains include M1-M6 and W3 at T0 (or T5 for W3) and T25. b Significant negative correlation between the size of the genomic deletions and strain fitness, shown for the left arm, the right arm and the entire genome. Linear regression lines include 95% confidence intervals. Statistics are given in the main text.
