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).

Soybean Mosaic Virus is a successful Potyvirus with a wide distribution range but having a restricted natural host range. It is a filamentous particle with 7500 Å length and 120 Å in diameter with single‐stranded, positive‐sense, polyadenylated RNA. Due to its restricted host range, it mostly causes diseases in the species of genus Glycine including Glycine max (cultivated soybean) and Glycine soja (wild soybean). The transmission of soybean mosaic virus is mostly done by mechanical transmission, aphid, or through seed. It can be controlled only by using the pathogen freed seeds, avoiding mechanical injuries, and by using the species having one or more R genes.
