Figure 4From: Assessing the evolutionary rate of positional orthologous genes in prokaryotes using synteny dataPAM distance distributions for orthologs pairs inside and outside synteny blocks. Part A (upper) compares all pairs of orthologs shared by closely related enterobacteria E. coli and S. enterica. Part B compares a more distant pair of genomes, E. coli and B. subtilis. The color code is given in box C, which also compares the respective mean of each distribution of PAM distances and the total number of orthologs shared by each pair of genomes analyzed in A and B.Back to article page
