Fig. 2

Schematic representation of the 15 lineages corresponding to complete sequences found in aphid’s genomes. The elements are arranged and colored (as in Figure 1) according to the clades they belong to. Potentially active copies are marked with asterisks. The lack of TA (TSD) is marked by a slashed zero in red. Blue arrows indicate TIR, while bold lines represent UTRs. A turned T shows the presence of polyAdenylation site “AATAAA”. In transposase gene, the three catalytic residues containing aspartic amino acids marked in red are indicated. The helix turn helix (HTH) region, the nuclear localization signal (NLS), and motifs related to WVPHEL are also mentioned. Sequences name: Apismar: elements from Acyrthosiphon pisum, Dnomar: elements from Diuraphis noxia and Mpmar: elements from Myzus persicae
