FIG. 2.

Sequence comparison of Edmonston wt and vaccine leader and trailer TCRs. Terminal 110 bases of genomic sequence (3′ to 5′) containing the leader TCR (nucleotides 1 to 107; part A) and trailer TCR (nucleotides 15785 to 15894; part B) of Edmonston wt are shown and labeled with genome nucleotide positions. Sequence motifs are illustrated on the sequence according to the key at the bottom of the figure. Relevant protein start or stop codons also are included. The sequence corresponding to the GE region in the leader TCR and the GS region of the trailer TCR are not shaded in gray to indicate that these sequence motifs may not function identically to their intergenic GE/GS counterparts. Illustrated below the wt sequence is the sequence comparison with vaccine strains. Nucleotide identity is given as a dot, and a typed nucleotide indicates disagreement with wt.
