Liu et al. (1993) were the first who expressed the full-length coat gene of soybean mosaic virus (SMV) in E. coli, while the appearance of VLPs was not reported. Kendall et al. (2008) used fiber diffraction, electron cryomicroscopy, microscopy, and scanning transmission electron microscopy to determine the symmetry of SMV, in parallel with the structure of a potexvirus, namely PVX (Chapter 21), as a reference. As a result, the low-resolution structure of both viruses was obtained. It was concluded that these viruses, and, by implication, most or all flexible filamentous plant viruses, share a common coat protein fold and helical symmetry, with slightly fewer than nine subunits per helical turn (Kendall et al. 2008).
