Appendix Figure 2. Top) Alignment of 1,794 bp of env nucleotide sequences corresponding to feline leukemia virus (FeLVA)-945 (AY662447) index sequence 154-1,869 bp. The shaded areas identify regions (indels) where panther FeLV (FeLV-Pco) sequences resemble those of FeLV-A, which rules out recombination with dissimilar endogenous FeLV sequences as represented in enFeLV-AGTT. Bottom) Panther sequences, with year of sampling (for example, FeLV-Pco-1058-03 was sampled in 2003); domestic cat subgroup A (FeLVA-945 and FeLVA-61E), recombinant (FeLVB-GA), and endogenous (enFeLV-AGTT) sequences are also shown. Matches to the reference sequence (Pco-1058-02) are indicated by a dot. Gaps are indicated by a dash.
