Figure 3

Maximum clade credibility tree for the North-South American genetic lineage. Tip and branch colors represent host origin (wild in green, domestic in orange). Tips were annotated with red stars for HP viruses. Blue letters (I to N) represent host shift events. Main genetic lineages, with information related to virus origin, are highlighted in the right part of the trees. Except for the ones identified with dashed lines, these lineages were monophyletic and supported by posterior probability values equal to 1. A detailed tree, including strain names, posterior probability values and 95% highest posterior density for time of the most recent common ancestors, is available in Figure S5.
