A bit earlier than for the previously described TuMV virions and VLPs, the electron cryomicroscopy was resolved to 4.0 Å for the watermelon mosaic virus (WNV) virions from infected squash plants (Zamora et al. 2017). It should be noted that WMV is a potyvirus with one of the widest host ranges and is present worldwide, infecting more than 170 different plant species from 26 families, including cucurbits and legumes. The WMV atomic model showed the conserved helical fold typical for other flexible filamentous plant viruses, including a universally conserved RNA binding pocket, which could be regarded as a potential target for antiviral compounds. Moreover, the authors concluded that this conserved fold of the coat protein is widely distributed in eukaryotic viruses and is also shared by nucleoproteins of enveloped viruses with segmented negative-sense single-stranded RNA genomes, including influenza viruses from the order Articulavirales (Chapter 33).

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.
