Barcoding region marked in red on the generalized secondary structure model of the nematode 18S rRNA (modified from Holovachov et al. 2015 with the permission from the publisher). Helices (1-23, 23/e1-23/e14, 24-50) are numbered according to Wuyts et al. (2002). Variable regions V1-V5 and V7-V9 (shaded in green) are numbered according to Neefs et al. (1990).
