Fig. 5. Transposon clusters enriched with H3K9me3, H4K20me3 and H3K27me3 contain relatively young TEs.
A, B) TEs belonging to the same TE subfamily were pairwise aligned to each other using BLAST. The median alignment score was determined for each TE subfamily by dividing the bitscores by the length of the aligned sequences. A) Retro- and B) DNA transposons were grouped according to clusters determined in Fig. 2A, B. The median alignment scores of the subfamilies were plotted for each cluster. The left and right hinges correspond to the 25th and 75th percentiles and the vertical line in between represents the median. The alignment scores of retro- and DNA transposons cannot be directly compared to each other, because of differences in library sizes (Supplementary Fig. 14A, B).
