This is initially displayed in an unrooted maximum likelihood (ML) tree
including all major groups of negative-sense RNA viruses
(A). Separate and more detailed ML phylogenies are then
shown for the Orthomyxoviridae-like (B),
Bunya-Arenaviridae-like (C), and Mononegavirales-like
viruses (D). In all the phylogenies, the RdRp sequences
described here from arthropods are either shaded purple or marked with
solid gray circles. The names of previously defined genera/families are
labeled to the right of the phylogenies. Based on their host types, the
branches are shaded red (vertebrate-specific), yellow (vertebrate and
arthropod), green (plant and arthropod), blue (non-arthropod
invertebrates), or black (arthropod only). For clarity, statistical
supports (i.e., approximate likelihood-ratio test (aLRT) with
Shimodaira–Hasegawa-like procedure/posterior probabilities) are
shown for key internal nodes only.
