  1. Occurrences are expressed as percentage of sequence reads having significant similarity out of the total.
  2. (a) Refers to LTR-RTs that could not be classified as Ty3-gypsy or Ty1-copia (so non autonomous, tracts of LTRs from non autonomous etc.)
  3. (b) Includes all the autonomous DNA elements; non autonomous ones such MITEs are excluded; helitrons are reported separately
  4. (c) Unclassified repeats
