¹ Distance between the telomeric junction and the first gene in base pairs
² This chromosomal end has two telomeric repeats followed by the telomeric junction
³ The first gene after the telomeric repeats is partially inserted inside the telomeric junction
⁴ Contigs harboring telomeric repeats not assembled in chromosome sized scaffolds. The subtelomeric region size indicated in the table corresponds to the whole unassigned contig sequence
