Figure 1.

Proposed secondary structure of minimum free energy of CEVd^COL. Discontinuous lines divide the secondary structure into the five structural domains (Terminal left, T_L; Pathogenicity, P; Central, C; Variable, V; and Terminal right, T_R). Conserved regions [central conserved region (CCR) and terminal conserved region (TCR)] are shaded in the T_L and C domains. P_L and P_R are boxed in the P and V domains. Boxed nucleotides (square boxes) show nucleotide changes found in CEVd^COL when compared with the severe variant CEVd^E‐117. Boxed nucleotide (round box) shows the nucleotide change found in the CEVd variants recovered from inoculated tomatoes.
