Figure 5: Reconstruction of the mitochondrial rearrangement scenarios in the evolution of flat bugs and proposed mechanism of tRNA gene rearrangement in the model of TDRL.
From: Rearrangement of mitochondrial tRNA genes in flat bugs (Hemiptera: Aradidae)

Phylogenetic tree were simplified from Fig. 4. Genes are transcribed from left to right except those underlined, which have the opposite transcriptional orientation. Rearrangements of tRNA genes were highlighted by color. IGS for the intergenic spacer. Eliminated genes were indicated by crosses and pointed to the relative IGSs by grey arrows.
