Figure 4 The mitochondrial genome composition and arrangement of Semisulcospiridae. The PCGs are colored based on their functional group (dark blue represents COX1-3, light blue corresponds to ND1-6, pink indicates CYTB and yellow signifies ATP6 and ATP8), rRNAs (12S and 16S) are represented by gray modules, and the positions of the tRNAs are portrayed using their single-letter amino acid code (green modules). The non-coding region is not displayed. Note: H. aristarchorum is highlighted in red.
