Fig. 5From: Horizontal transfer of a retrotransposon between parasitic nematodes and the common shrewPhylogeny of RTE1_Sar in nematodes and S. araneus. Phylogeny was estimated for the ten species that had more than ten copies of RTE1_Sar and suggests a horizontal transfer event. C. elegans RTE-1 was used as outgroup.
