Additional file 2: of Origin and higher-level diversification of acariform mites – evidence from nuclear ribosomal genes, extensive taxon sampling, and secondary structure alignment

Secondary structure alignments. A-B: Two FASTA files containing consensus secondary structure alignments of the 18S and 28S genes. Secondary structure notations masks: brackets “()”, “{}”, and “< >“ indicate paired sites; dots “.” indicate unpaired sites, and asterisks “*” indicate regions of ambiguous alignment (RAAs). Notations for stems and variable regions follow [91] and [92, 93] for the SSU variable region 4 (V4). Length variation for each RAAs is also given separately. (RAR 211 kb)
