Figure 1 in Phylogenetic analysis of Zygaenoidea small-subunit rRNA structural variation implies initial oligophagy on cyanogenic host plants in larvae of the moth genus Zygaena (Insecta: Lepidoptera)

Figure 1. Secondary structure model of the SSU (18S) rRNA gene sequence of Zygaena (Mesembrynus) sarpedon lusitanica Reiss, 1936 (Lepidoptera: Zygaenidae; accession no. AJ830858) and structure variation in the helices E10-1 and E23-12 among species of the subfamily Zygaeninae. Nucleotides in the model are continuously numbered beginning at the 5′-end of the molecule; tick marks identify every tenth base. Light shading indicate helices numbered according to Wuyts et al. (2002). S1–S6 (dark shades) denote areas with variable secondary structure in the subfamily Zygaeninae. Roman numerals specify the domains I, II, III and IV. The following ambiguity code has been applied: A/C = M, C/U = Y, G/A = R.
