FIG. 3.
Computer prediction of secondary structures (SL5) in the region preceding the gag initiation codon in different MVV isolates and CAEV. (A) Mfold analysis carried out with fragments corresponding to nt 79 to 589 of isolate 1514. Only sequences around the gag initiation codon are shown. Boxes indicate the gag initiation codon. The deletion of 1514 is shown with gray shading. (B) Structure prediction for isolate 1514, using only sequences corresponding to the structure common to the other isolates. (C) Phylogenetic comparison of predicted SL5 structures. The 1514 SL5 was used as a prototype. Nucleotide changes occurring in other isolates are indicated, along with the isolate name in superscript.
