Maximum likelihood phylogenetic tree based on the polyprotein amino acid sequences of Ty3/Gypsy elements from the group “OSVALDO/ULYSSES”. Only bootstrap values greater than 50% (red dots) and greater than 70% (black dot) are indicated. The tree has been rooted by the Batumi element from D. melanogaster and we also added elements from the two other groups of Ty3/Gypsy (Tirant and BLASTOPIA from D. melanogaster). The names of the species are abbreviated as follows: DAn, D. ananassae; DBi, D. biarmipes; DBp, D. bipectina; Dbuz, D. buzzatti; DEl, D. elegans; DEu/Deu, D. eugracilis; DFi, D. ficusphila; DGri/DG, D. grimshawi; DKi, D. kikkawai; DMel, D. melanogaster (in red); DMoj/Dmoj, D. mojavensis; DPer/DP, D. persimilis; DPse/Dpse, D. pseudoobscura; DRh, D. rhopaloa; DSe, D. sechellia (in green); DSi, D. simulans (in blue); DTa, D. takahashi; DVir/DV, D. virilis; DWil, D. willistoni; DYa/DY, D. yakuba (in pink). Yellow stars represent cases of confirmed horizontal transfers (see details in Additional file 3: Figure S1c)
