Fig. 2From: Differential retention of transposable element-derived sequences in outcrossing Arabidopsis genomesDistribution of nucleotide identity of TEs to the consensus sequence of their TE family for the three species. This statistic is used as a proxy for the relative age of TE insertion. Based on this distribution, we define “old” and “young” TEs based on a threshold of 90% identity represented by the dashed vertical line (close to the lowest point of the distribution)Back to article page
