FIG. 10.

Multiple-sequence alignment of the junction region and the 3′ untranslated region. (a) Nucleotide sequences of the junction regions of SDV and several alphaviruses were aligned. Nucleotides conserved with those of SDV are indicated with dots. The three invariant nucleotides which are modified in the SDV sequence are indicated with asterisks. (b) Alignment of consensus 19-nucleotide 3′-end sequences of SDV and several alphaviruses (19). Dots indicate conserved nucleotides. Dashes have been introduced to optimize the alignment. Abbreviations are as described in the legend to Fig. 7. BEB, Bebaru; UNA, Una; BCR, Buggy Creek; MID, Middelburg.
