Extended Data Figure 7. Sequence alignment of the core E1 region.

Alignment contains VEEV sequences from lineage K, L and M shown in the phylogenetic order determined in supp figure 1. Lineage K sequences are shaded in purple, lineage L sequences are shaded in blue and lineage M sequences are shaded in green. The alignment was made using TC83 (L01443 IAB) as the reference sequence. Varying nucleotides between TC83 and 307537 (KC344519 ID) are highlighted in red in the reference sequence. Identical nucleotides are represented as periods (.).
