Figure 1

Nucleotide alignment of the Serva ILTV sequence and the concatenated ILTV reference sequence. Single vertical black lines indicate single nucleotide differences. Wider black boxes indicate larger regions of sequence differences, including areas where there are large gaps. Dashes indicate single base gaps in sequence alignments. The alignment was performed using Clustal W version 2.0. The locations and sizes of predicted ORFs and origins of DNA replication were annotated using the Geneious software package. The solid lines below the residue numbers indicate the locations of the internal and terminal repeat sequences.
