Turnip mosaic virus
Encyclopedia
Turnip mosaic virus is a Potyvirus
of the family Potyviridae
that causes diseases in cruciferous
plants, among others. The virus is usually spread by 40-50 species of aphids in a non-persistent manner. Infected plants, especially the natural hosts, show symptoms such as chlorotic local lesions, mosaic, mottling, puckering or rugosity. TuMV is a positive-sense single stranded RNA virus
, consisting of a non-enveloped, helical capsid
that is filamentous and flexuous, with an average length of 720 nm. The TuMV genome is linear and monopartite (single particle). The virus has a thermal inactivation point (TIP) of 62°C, and longevity in vitro (LIV) of 3–4 days.
Potyvirus
Potyviruses infect plants and belong to the family Potyviridae. The genus is named after the type virus - Potato Virus Y.The Potyvirus, like the Begomoviruses, have ~30% of the currently known plant viruses and have at least 180 definitive and possible members...

Potyviridae
The Potyviridae are a family of plant viruses. They are . Their genome is composed of positive-sense RNA which is surrounded by a protein coat made up of a single viral encoded protein called a capsid. All induce the formation of virus inclusion bodies called in their hosts...

Capsid
A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. The capsid encloses the genetic...
