(A) Predicted secondary structures of selected ENEs. Note that the Tad1_NCr and Gypsy2_DFa-I ENEs are in inverted orientation. (B) Alignment of TE DNA and Dicistrovirus cDNA sequences corresponding to 50 ENEs and their flanking regions. Only standard-orientation ENEs are included. For clarity, sequences with ≥95% redundancy were discarded. Nucleotide coloring and shading are as in Figure 2. The organism name abbreviations are as follows: Dictyostelium fasciculatum - DFa, Polysphondylium pallidum PN500 – PPP, Saccharum hybrid cultivar –SHC, Melampsora larici-populina –MLP, Mycosphaerella graminicola IPO323 – MGI, Punctularia strigosozonata HHB-11173 –PSH, Coniophora puteana- CPu, Laccaria bicolor S238N – LBS. Other organism name abbreviations are as in Figure 2. MCDiV, TSV and MRTV stand for mud crab dicistrovirus, Taura syndrome virus and Macrobrachium rosenbergii Taihu virus, respectively.
