Structure characteristics of Buster1 (A) and Buster2 (B) and sequence logo of the regions flanking Buster1_NA1_SM and Buster2_NA2_NH insertions. The 15Â nt upstream and downstream of all full-length copies of these families in Schmidtea mediterranea and Nycticeius humeralis are presented in each logo. The vertical axis is a measure of sequence information, which has a maximum value of 2 and is proportional to the level of sequence conservation at each position. The rectangles indicate their direct repeats. Their TIRs were shown using underlines, and numbers indicated their alignment positions.
