a A representative tomogram slice of SFTSV virions. A total of 118 tomograms were collected for this study. b Zoom-in tomogram slices showing the pentagonal (orange) and hexagonal (cyan) densities on virion surface. The left and right panels are essentially the same except that the latter are annotated with pentagons and hexagons. c FSC curve for the subtomogram averaging density map of the hexon peplomer. d Cross-section view of the hexon density map produced by subtomogram averaging. OL outer leaflet, IL Inner leaflet, TM transmembrane domain, IM intramembrane domain. e The density map of hexon peplomer fitted with a pseudo-atomic model. The map is shown as transparent surface to reveal the tubular feature overlaid with helices.
