Virus
A virus is a small infectious agent that can replicate only inside the living cells of organisms. Viruses infect all types of organisms, from animals and plants to bacteria and archaea...

es, including the following genera:
  • Genus Luteovirus
    Luteovirus
    Luteovirus is one of three genera in the luteoviridae family whose primary hosts are plants. The genera also contains the polerovirus and enamovirus. The geographical distribution of luteovirus is widespread, with the virus primarily infecting plants via transmission by aphid vectors. The virus...

  • Genus Polerovirus; type species: Potato leafroll virus
    Potato leafroll virus
    Potato leafroll virus is a member of the genus Polerovirus and family Luteoviridae. The phloem limited positive sense RNA virus infects potatos and other members of the family Solanaceae. PLRV was first described by Quanjer et. al. in 1916. PLRV is transmitted by aphids, primarily the green...

Luteoviridae

The luteoviruses are a group of plant viruses. The virion particle is non-enveloped, the nucleocapsid is isometric and 26-30 nm in diameter with icosahedral symmetry. The genome
Genome
In modern molecular biology and genetics, the genome is the entirety of an organism's hereditary information. It is encoded either in DNA or, for many types of virus, in RNA. The genome includes both the genes and the non-coding sequences of the DNA/RNA....

 ranging in length from 5641 to 6900 nucleotides, and replicate within the cytoplasm. Luteoviruses can act as helper viruses for Umbravirus
Umbravirus
The genus Umbravirus includes plant viruses. The genus has not yet been assigned to a family but it is closely allied to the Tombusviridae.Umbraviruses do not encode their own coat protein, but use the coat proteins of 'assistor viruses' from the family Luteoviridae to produce virions, allowing...
