Mitochondrial gene arrangement of Limulus polyphemus, Dermatophagoides pteronyssinus and Steganacarus magnus. Graphical linearisation of mt genomes is presented according to . Gene sizes are not drawn to scale. J stands for majority and N for minority strand. Protein coding and rRNA genes are abbreviated as in the abbreviations section. tRNA genes are abbreviated using the one-letter amino acid code, with L1 = CUN; L2 = UUR; S1 = AGN; S2 = UCN. White boxes represent genes with the same relative position as in the arthropod ground pattern, L. polyphemus. Light-gray boxes represent genes that changed positions relative to L. polyphemus; dark-gray boxes represent genes that changed both position and orientation. Circular dots between the genes of D. pteronyssinus represent conserved gene boundaries compared to L. polyphemus. Square dots between the genes of S. magnus represent conserved gene boundaries compared to D. pteronyssinus.
