Figure 6. Phylogenetic assignment for FeV4.

An unrooted phylogenetic tree was derived from the polymerase protein sequences of the Mononegavirales family viruses, which infect insects, along with the partial of the FeV4-like sequences from different Formica host species. The Formica virus clade is highlighted in gray and bootstrap values are shown above the branches. The branches between the FeV4-like sequences are preliminary, given that the sequences of these viruses (with ambiguous/uncalled bases) are only partial. An asterisk (*) denotes short FeV4-like sequence.
