Extended Data Fig. 6: Evolution of vertebrate-associated positive-sense RNA virus genomes.

Representative genomes from positive-sense RNA virus families or genera are shown. The regions that encode major functional proteins or protein domains are labelled on each of the genomes. Homologous regions within or between viral families are connected by orange dotted lines. Host associations are reflected in the colour of the virus names. Host association colour schemes and the abbreviations of functional domains are described at the bottom of the figure.
