Alignment of endogenous viral element (EVE) transcripts with similarity to Bornaviridae, Filoviridae, and Parvoviridae sequences. Sequences were identified from marsupial RNA-Seq reads using a bioinformatics workflow and the viral identity was determined with a BLASTx search against the NCBI non-redundant database. Sequences were translated and mapped to the viral protein with which they share the highest identity. Grey lines represent transcripts from the thirty-five marsupial transcriptomes. Genes coloured blue are structural genes, and genes coloured red are non-structural genes. The proteins are gradated based on the conservation of amino acids between members of the viral families; light green represents conserved regions and grey represents more variable regions. Red boxes highlight areas containing recognised viral enzymatic motifs.
