FIG. 3.

TcTREZO insertion site. Comparison of the 5′ and 3′adjacent sequences flanking TcTREZO in the contigs of the TcGeneDB. The accession numbers of the corresponding contigs are indicated at the left. Alignments were done by Clustal W. The first block (A) shows a conserved region of 68 nt upstream of TcTREZO, and the second block (B) shows the 3′ region of this element. Sequences corresponding to the conserved residues are shaded in black (>80% conservation) and gray (60 to 80% conservation); no shading denotes residues with <60% conservation. A schematic representation of TcTREZO is shown at the top. The upstream and downstream regions are shown by hatched boxes.
