Effects of the sequence heterogeneity found in variants characterized so far from CChMVd-S and -NS strains on the secondary structure predicted for CChMVd RNA. Mutations of CMNS 6, 26, 38, and 41, which are presumably artifactual for the reasons stated in the text, are not included. Insertions and deletions are denoted by symbols + and −, respectively. For other details of the CChMVd reference variant, see Fig. 3.
