FIG. 8.
Schematic illustrating the common features present in SLC of BMV and CMV subgroup I and II RNAs. The RNAs have a short stem region with an internal bulge, followed by a rigid stem-loop region. The conserved CA dinucleotide in CMV subgroups I and II is indicated in bold. B-SLC, C-SLC3, C-SLC5, and Q-SLC were generated using the mfold program (24).
