Figure 2

The orange, yellow and blue boxes indicate transposons, untranslated regions, and coding sequences respectively. The numerals above the blue boxes show exon numbers, and the arrows show the orientations of the transposase genes. The filled triangles are the 122-bp and 104-bp tandem repeats in the 5′ and 3′ sub-terminal regions respectively. TpnA3 lacks exons 7 and 8, and TpnA4 has a gap represented by a white box, as well as three frame shift mutation indicated by the vertical bar with −1 and +1 in the exon 10 and 13.
