R1 and R2 element insertion sites in honey bee 28S rDNA sequences, and variable R2 element 5′-UTRs. (A) Predicted secondary structure of domain IV of honey bee 28S rRNA, with asterisks depicting R1 and R2 element insertion sites. (B) Variable 5′-junction of R2 element insertion sites. Shaded region in type II elements depict conserved regions flanking a highly variable junction. (C) Three-prime junction of partial putative R1 element in honey bee 28S rDNA. Shaded sequence depicts 28S rDNA. Note: no 5′-junction was recovered for this partial R1 element (see text). (D) Conserved 758 nts in the 5′-UTR of type II R2 elements. Boxed sequence contains variation across unassembled reads. (E) Conserved 335 nts of the 5′-UTR of type I and type II R2 elements. See Fig. 2 legend for explanations of base pair symbols, helix numbering and reference for software used to construct structure diagrams.
