(A) Organization of the A+T-rich regions in the Anoplophora horsfieldi mitogenomes. The square box represents the feature sequence CSB1-3. The poly-T stretch is underlined while the poly-A stretch is double underlined. The single microsatellite T/A repeats sequence are indicated by single underlining. (B) The colored ovals indicate the tandem repeats; the remaining regions are shown with different color boxes. TR1-3 represents different types of repeat sequences. Horizontal lines with solid dots at both ends represent the structures of poly (A), poly (T) and poly (TA), respectively.
