FIG. 4.

Comparison of M/F intergenic regions from Edmonston wt and vaccine viruses. The description of this figure is similar to that for Fig. 2. One line of dots indicating homology to all vaccines is shown under the wt sequence if there were no base changes to report. The sequence shown in this figure extends beyond the noncoding intergenic region to show the position of the three F gene AUG codons. The second AUG codon is the predominately used initiation codon (5). Vaccine virus names are abbreviated as follows: AIK-C (AIK), Moraten and Schwarz (Mor/Sch) Rubeovax (Rubeo) and Zagreb (Zag).
