Figure 1.

Reconstruction of the Helitron1 (A), Helitron2 (B), and Helitron1_CE (C) consensus sequences. The consensus sequences are schematically depicted as rectangles. Contiguous copies of Helitrons that we used for reconstruction of the consensus sequences are shown as bold lines beneath the rectangles. Gaps in the lines mark deletions of corresponding regions of the consensus sequences. GenBank accession nos. and sequence coordinates are indicated. Genes and their coordinates in the consensus sequences are indicated above the rectangles. Genes coding for proteins composed of the Rep and helicase domains are shaded in gray. The AT target sites are encircled.
