Figure 1

Schematic representation of the reconstructed full-length Mar compared to the canonical Mar element (MITE). Common regions are indicated, including terminal inverted repeats (black boxes). The transposase coding region with the Dimer_Tnp_hAT domain coding region is also shown. Below are the schematic representations of copies found in D. tropicalis and D. willistoni. Only indels of more than 12 nucleotides are represented. Arrows indicate the primer annealing regions. The primers MarF and MarR were used to amplify Mar from the willistoni group species, and Mar2F and Mar2R were used to sequence the D. tropicalis clones
