Barley stripe mosaic virus (BSMV) is the type member of the genus Hordeivirus, rigid, rod-shaped viruses in the family Virgaviridae. We have used fiber diffraction and cryo-electron microscopy to determine the helical symmetry of BSMV to be 23.2 subunits per turn of the viral helix, and to obtain a low-resolution model of the virus by helical reconstruction methods. Features in the model support a structural relationship between the coat proteins of the hordeiviruses and the tobamoviruses. - Highlights: • We report a low-resolution structure of barley stripe mosaic virus. • Barley stripe mosaic virus has 23.2 subunits per turn of the viral helix. • We compare barley stripe mosaic virus with tobacco mosaic virus.
