Structural characteristics of mariner lineages copies. A - Proportion of copies at two different conservation stages: with 2 TIRs and with an uninterrupted ORF between 330 and 363 AA in all lineages with at least 10 independent copies. An asterisk before the name denotes MITE sublineages. Arrows indicates full-length lineages and the derived MITEs sublineages. B - Mean divergence of the same lineages relative to the consensus sequence. Black bars are MITE sublineages, whites bars are their full-length partners.
