FIGURE 3.

Orthologous tRNA gene sets for the five organisms analyzed. Blue and yellow boxes show polycistronic tRNA clusters in EcK12, and gray boxes show mixed rRNA–tRNA operons (Inokuchi and Yamao 1995). Purple boxes show inverted regions when compared with the ancestral reconstruction. Orange boxes show regions with a high number of insertions. The numbers on the left indicate the genomic coordinates of tRNA genes in EcK12. The numbers at the bottom indicate the total number of functional tRNA genes in each genome.
