Cumulative transcriptional activity of subgenome-specific TEs. On the left, cumulative transcriptional levels of L subgenome-specific TEs were reported; On the right, cumulative transcriptional levels of S subgenome-specific TEs were reported. “Unclear” means TEs that are not specifically classified as DNA transposons, LINE, SINE, and LTR retrotransposons, “non-LTR” retrotransposons are referred to retrotransposons that are not specifically classified as LINE or SINE retrotransposons, and “Retro” is referred to retrotransposons that are not specifically classified as LINE, SINE, LTR or non-LTR retrotransposons
