Virus classification
Group: Group IV ((+)ssRNA)
Family: Tombusviridae
Genus: Necrovirus
Type species
Tobacco necrosis virus A

Necrovirus is a genera of Tombusviridae. It is named after the type species, Tobacco necrosis virus A.


Tentative species[edit]

Status unknown[edit]


Icosohedral structure, each face containing six identical capsid proteins, arranged in a rotationally symmetric manner.


While necroviruses are spread by mechanical means, often relating to propagation, most, if not all, species have a common fungal vector, the Chytridomycetes species Olpidium brassicae
