Figure 4.

Diverging 3ʹUTR architecture in four representative TBEV strains, Neudoerfl (A), TBEV-2871 (B), 886–84 (C), and Senzhang (D). Core and variable regions are underlined in red and grey, respectively. Structural homologs of evolutionarily conserved RNA elements are depicted in the same colour for all strains (matching the colours used in Fig. 3). Structural components that are not found in all homologs, such as closing stems of some CSL4 and CSL2 elements, or additional short stem loops that are only predicted in particular strains, are not considered conserved.
