Soybean mosaic virus (SMV) is a member of the plant virus genus Potyvirus (family Potyviridae). It infects mainly plants belonging to the family Fabaceae but has also been found infecting other economically important crops.

Potyvirus is a genus of positive-strand RNA viruses (named after its type species, Potato virus Y (PVY)) in the family Potyviridae.Plants serve as natural hosts. Like begomoviruses, members of this genus may cause significant losses in agricultural, pastoral, horticultural, and ornamental crops.
Replication and movement of soybean mosaic virus (SMV) Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration. Replication follows the positive-stranded RNA virus replication model. Positive-stranded RNA virus transcription is the method of transcription. Translation takes place by −1 ribosomal frameshifting.
The genome of sobemoviruses exemplified by Sesbania mosaic virus. Solemoviruses have a positive-sense, single-strand RNA genome. The length of the genome is 4652 bp. The 3' terminus does not have a polyA-tail. The 5' terminus has a genome-linked viral protein (VPg).
A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses.
Watermelon mosaic virus (WMV) also known as Marrow mosaic virus (Raychaudhuri and Varma, 1975; Varma, 1988), Melon mosaic virus (Iwaki et al., 1984; Komuro, 1962), and until recently Watermelon mosaic virus type 2 (WMV-2), [1] is a plant pathogenic virus [2] that causes viral infection (sometimes referred to as watermelon Mosaic disease) in many different plants.
The virus, particularly maize dwarf mosaic disease caused by SCMV, has been among the most damaging diseases affecting maize production in China due to the large affect it has on yield. [9] The high incidence of co-infection and the occurrence of new strains or genome variations indicate that SCMV will continue to be a threat to industry.
