Figure 4.

Rescaled timing of the maximal growth rate. The time required for the cell populations to achieve the best growth performance was calculated following the rescaling. Box plots represent every 11 to 30 repeated measurements for each condition. Panels from top to bottom represent growth in LB, MAA and M63, respectively. The genomes (Strain No.) from Nos. 0 to 28 are indicated in order from the top to bottom in each panel. Spearman’s rank correlation coefficients between the mean timing and the length of accumulated deletions are indicated along with the statistical significance.
