Geothermal and hypersaline environments are rich in viral particles, among which spindle-shaped morphologies predominate. Currently, viruses with spindle- or lemon-shaped virions are unique to Archaea and belong to two distinct viral families. The larger of the two families, the Fuselloviridae, encompasses spindle-shaped viruses with very short tails, which infect Sulfolobus solfataricus and close relatives. Sulfolobus spindle-shaped virus 1 (SSV1) is the best-known member of the family and was one of the first hyperthermophilic archaeal viruses to be isolated. However, our knowledge of fuselloviral life cycles and the relationships between these viruses and their hosts is still limited. As a …

The structure and assembly of many icosahedral and helical viruses are well-characterized. However, the molecular basis for the unique spindle-shaped morphology of many viruses that infect Archaea remains unknown. To understand the architecture and assembly of these viruses, the spindle-shaped virus SSV1 was examined using cryo-EM, providing the first 3D-structure of a spindle-shaped virus as well as insight into SSV1 biology, assembly and evolution. Furthermore, a geometric framework underlying the distinct spindle-shaped structure is proposed.
