Fig. 6. ITS2 in A huge undescribed diversity of the subgenus Hystricochaetonotus (Gastrotricha, Chaetonotidae, Chaetonotus) in Central Europe

Fig. 6. ITS2 of the subgenus Hystricochaetonotus Schwank, 1990. A. Putative consensus secondary structure. The central loop radiates four unequally long helices. The first two helices are highly conserved, while the two following helices are much less conserved. For localization of helix 10, which is made by the interaction of 3'-end of 5.8S and 5'-end of 28S, see Fig. 7. B. Two different views on the tertiary structure, showing that helices II and IV run in parallel. C. Structure logos of helices I‒IV. The height of a base is proportional to its frequency in the multiple sequence alignment.
