Timing of the bursts of the three retrotransposons, RIRE2, ATLANTYS, and COPIA, in O. granulata. a Timing of the burst of RIRE2. b Timing of the burst of ATLANTYS and COPIA. For each LTR retrotransposons in O. granulata genome, the curves represent the date of divergence in MYA translated from the observed divergence, using the molecular clock (1.3×10⁻⁸ substitutions per site per year from Ma and Bennetzen⁴⁷). The groups of paralogs used to compute the pairwise distances are defined with EMBOSS. The y-axis represents the total number of copy equivalents
