Figure 2.

Maximum likelihood phylogenetic trees of representative sequences within the genus Circovirus. Sequences were aligned using MAFFT²⁴, trees generated using IQ-Tree²³ on find best model setting with ModelFinder²⁵ with 1000 ultrafast bootstraps²⁶ and visualized with iTOL²⁷. ElkCV is indicated in bold text and with “•” before the sequence name in all trees. (a) Full mid-point rooted phylogenetic tree generated from representative Circovirus complete genome nucleotide sequences (model TIM + F + R5). (b) Pruned trees showing only ElkCV and sequences on closely related branches from complete genome nucleotide sequences (top black box), Rep protein amino acid sequences (middle gray box, model LG + I + G4) and Cp protein amino acid sequences (bottom gray box, model PMB + R3).
