Phylogenetic analysis of SINE elements in E. histolytica and E. dispar. A) Schematic representation of an E. dispar locus containing a copy of Ed_SINE3 (green boxes) interrupted by the insertion of an Ed_SINE2 (white box) generating target site duplications (TSD, black boxes). The diagonal stripped box represents an Ed_LINE2 located at the end of the scaffold. Scaffold GenBank accession is indicated on the left. B) Phylogenetic analysis of the three SINE families found in E. histolytica and E. dispar. All tree nodes have a bootstrap value of 1000 (1000 replicates).
