FIG 4.

Evolutionary history and genome structure of negative-sense single-stranded RNA viruses discovered in this study. The maximum-likelihood phylogenetic trees based on RdRp protein alignments show the positions of the newly discovered virus among neighboring members in the corresponding virus family or order. Genome structures of the representative viral OTUs are shown right next to their phylogenies. Circles with different colors indicate the corresponding arthropods from which these viruses are discovered.
