Predicted transcription motifs for the two control regions of the MED mitogenome. (A) The first control region (CR1) and conserved transcription motifs. (B) The second control region (CR2) and conserved transcription motifs. The red line under the [TA(A)n]-like stretch represents the different motif from the New World species. (C) Tandem repeat in the second control region of MED and New World mitogenomes. In MED, R1-R7 represents the tandem repetition in the second region. The nucleotides with red color mean divergence between repeat units and the overlap means the two repeat units share the same 10 nucleotides. The repeat unites of R1-R5 are 44 bp long and the length of R6, R7 are 169 bp. The 125 bp represent R6 and R7 have the same 125 bp repeat nucleotides. In New World species, R1-R6 represents the six repeat regions in the second region. R1-R4 repeat unit is 44 bp long and R5, R6 repeat length is 38 bp.
