Phylogenetic inference performed based on the coding regions Gag, Pol, and Env. The trees show sequences of Betaretroviruses from bats and primates that were obtained from NCBI. The numbers at each main node in the tree correspond to bootstrap values in percentage (1000 replicates). The scale bar corresponds to the nucleotide divergence per site between sequences. The sequences from this study formed a monophyletic clade with other bat DrERV sequences from the database, as indicated by the underlined blue color. Meanwhile, the SMRV sequences clustered in a nearby branch, forming a paraphyletic group with non-human primate Betaretroviruses in all trees, highlighted in red, indicating a certain phylogenetic correlation
