  1. CDS, coding DNA sequences; CNE, conserved non-coding elements. Sequence length is shown in base pairs (bp). More details are shown in Supplementary Tables 31–33.
  2. *If all protein-coding exons are removed, this value decreases to 96,465,841 bp (~9.7 Mb smaller).
  3. †If all protein-coding exons are removed, this value decreases to 29,744,189 bp (~3.7 Mb smaller).
  4. ‡CNEs with clear blast hits (1e-5) to known proteins, tRNAs, rRNAs and so on.
  5. §Protein hits accounted for 2,272,249 bp.
  6. ∥CNE candidates with <70% identity, <75 bp long, adjacent to CDS or homologous to known proteins/ tRNAs/rRNAs/snoRNAs/scRNAs/snlRNAs were removed.
