Ormycoviruses are associated with arthropod transcriptomes. (a) Phylogenetic inference of the extended diversity of ormycoviruses. Viruses identified in this study are indicated by red circles. The arrow indicates the position of the virus that appears to use the ciliate genetic code. Clades are annotated according to designations established by Forgia et al. (2022). The catalytic triad encoded in each palm domain is denoted in grey. The tip labelling scheme for unnamed viruses (denoted by quotation marks) is the same as in Fig. 1. Support values are shown at select nodes as sh-aLRT/UFBoot. Tree branches are coloured by the location where each tip was sampled, and they are scaled by amino acid substitutions. (b) Library composition of select arthropod assemblies. The graph labels correspond to the TSA project ID.
