Tobacco necrosis virus (TNV) is a plant virus of the family Tombusviridae.
It is transmitted by the fungus Olpidium brassicae.
TNV has wide host range (88 plant species). The virus can be isolated from roots of apparently healthy plants. TNV is the helper virus to several satellite viruses that are dependent on TNV for replication of their genome.
