Fig. 2

The length (indicated by asterisks) and number (indicated by circles) of various gene types in different Buchnera strains, as well as the length of the genome and non-coding regions. Different groups are represented by different colored lines. Various background colors represent Buchnera from different subfamilies of aphids, labeled with text in corresponding colors. The order of Buchnera strains from left to right corresponds to the order on the phylogenetic tree. CDS: coding sequence, mRNA: messenger RNA; tmRNA: transfer mRNA.
