*The '% of genome' includes all LTR-RT sequences (in the nuclear genome) for each superfamily, rather than just complete and solo-LTR elements. Fragments of LTR-RTs were also found in the mitochondrial (2.74%) and chloroplast (0.05%) genomes. ^†Elements containing indels were included as complete elements provided they retain a substantial part of both their LTRs.
