From: 18S rRNA variability maps reveal three highly divergent, conserved motifs within Rotifera
The three exemplar rotifer 18S rRNA molecules: A Adineta vaga (Bdelloidea), b Brachionus plicatilis (Monogononta), and c Seison nebaliae (Seisonacea). Individual nucleotides are coloured according to their relative rate of evolution (for Bdelloidea, Monogononta, and all Rotifera, respectively) as determined using TIGER (see inline legends) and hypervariable regions V1–V9 are labeled and outlined in blue. In addition, the maximal extent of the variable deletion at the 3'-end of the V3 region in bdelloids (see Fig. 2) is highlighted using square parentheses. Each map was created initially using VARNA v3.93 [59] and modified using Adobe® Illustrator® 2020 to match the traditional topology of the eukaryotic core structure as closely as possible. Empty circles were added at the terminal ends of the sequences as needed to present the presumed full length of the molecule for each species
