Figure 2From: Tempo and mode of early gene loss in endosymbiotic bacteria from insectsRelationship between frequency of gene loss in endosymbionts and adaptive codon bias (CAI) of the E. coli ortholog at different depths of the tree. y-axis: percentages of genes lost at least on one occasion between different nodes (or a node and a tip), x-axis: CAI classes of E. coli K12.Back to article page
