Clover yellow vein virus
Encyclopedia
Clover yellow vein virus (ClYVV) is a plant pathogenic virus in the genus Potyvirus
and the virus family Potyviridae
. Like other members of the Potyvirus genus, ClYVV is a monopartite strand of positive-sense, single-stranded RNA
surrounded by a capsid made for a single viral encoded protein. The virus is a filamentous particle that measures about 760 nm in length. This virus is transmitted by several species of aphids in a nonpersistent manner and by mechanical inoculation.
(BYMV). With time, using serological, host range studies and eventually sequence data, this proved to be true. For example, several species of Commelinaceae
, reported to be infected by BYMV, were found susceptible to ClYVV instead . ClYVV and BYMV are now considered to be different potyviruses, both of which infect many members of the Fabaceae
(or Leguminosae) worldwide.
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...

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...

Geographic Distribution and Host Range
Clover yellow vein virus, first named in 1965 , was isolated from white clover (Trifolium repens) in a garden in England. A survey of English pastures found it to be widespread throughout England . In 1969 a similar virus was isolated in Canada and it was speculated at the time that the virus was also common in the United States but had been misidentified as an strain of Bean yellow mosaic virusBean yellow mosaic virus

Commelinaceae
Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with an estimated 650 species in 40 genera. Well known genera include...

Fabaceae
The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, is a large and economically important family of flowering plants. The group is the third largest land plant family, behind only the Orchidaceae and Asteraceae, with 730 genera and over 19,400 species...
