Structure of Flexible Filamentous Plant Viruses
Abstract
Flexible filamentous viruses make up a large fraction of the known plant viruses, but by comparison with other viruses, very little is known about their structures. We have used fiber diffraction, cryo-electron microscopy, and scanning transmission electron microscopy to determine the symmetry of a potyvirus, soybean mosaic virus, to confirm the symmetry of a potexvirus, potato virus X, and to determine low resolution structures of both viruses. We conclude that these viruses and, by implication, most or all flexible filamentous plant viruses share a common coat protein fold and helical symmetry, with slightly less than 9 subunits per helical turn.
