Figure 1. Phylogeny of Ara–3 population.

Figure 1

Symbols at branch tips mark 29 sequenced clones; labels are shown for clones mentioned in main text and figures. Shaded areas and coloured symbols identify major clades. Fractions above the tree show the number of clones belonging to the clade that yielded Cit+ mutants during replay experiments (numerator) and the corresponding total used in those experiments (denominator). Inset shows number of mutations relative to the ancestor. The solid line is the least-squares linear regression of mutations in non-mutator genomes; the dashed line is the corresponding regression for mutator genomes.
