SIVagm Infection in Wild African Green Monkeys from South Africa: Epidemiology, Natural History, and Evolutionary Considerations

Figure 3

Molecular clock trees for pol gene based on the newly derived SIVagmVer sequences from vervets in South Africa.

Relaxed molecular clock tree show the ultrametric divergence pattern between lineages. Calibration was based on internal nodes indicated with a red circle, by setting priors that span the presumed divergence MRCA date ranges, 100,000–3,000,000 years for SIVagm sequences surrounding the Drakensberg Mountains in South Africa, and 10,000±1,000 for SIVdrl sequences sampled from Bioko Island [2]. Internal nodes show divergence date estimates. Sequences are colored based on the territory from which they were sampled, with South African sequences colored red, green and blue, for Free State, KwaZulu Natal and Eastern Cape, respectively, and Bioko sequences colored in yellow.
