Distribution of long interspersed elements (LINEs) and telomeric repeats around the candidate regions of ancient chromosomal fusions. Genomic sequences with gaps were divided into 10-kb windows, and the ratio of the length of all (solid lines) or R1-clade (dotted lines) LINEs in total genomic sequence without gaps was calculated for each window. Filled squares indicate candidate regions. Horizontal dotted lines indicate 13.8%, average of LINE content in the B. mori genome (Osanai-Futahashi et al., 2008). Vertical lines indicate insertion sites of a TTAGG repeat and truncated copies of TTAGG repeat-specific retrotransposons, TRAS3 and SART1.
