Tobacco Necrosis Virus A
''Tobacco necrosis virus A'' is a plant pathogenic virus of the family ''Tombusviridae''. Hosts and symptoms Tobacco necrosis virus (TNV) can thrive on a handful of viable hosts. These hosts include tobacco, zucchini, cucumbers, carrots, French bean, tomatoes, potatoes, and tulips. There are a variety of symptoms that are dependent on the host species. In infected plants, abnormal coloring or necrotic tissue in the leaves may occur and roots may have lesions. If bark is present on the plant, it may become discolored. Fruit or tubers can become covered with sunken and discolored spots and can be smaller overall. On a whole-plant scale, damping off or early dying may occur. Management Currently, there is not a way to chemically control tobacco necrosis virus. There are, however, cultural management options to reduce the risk of the virus. Prior to planting, one can reduce risk of this disease by investigating the history of their soil for past presence of TNV or of its fungal ho ...

Tombusviridae
''Tombusviridae'' is a family of single-stranded positive sense RNA plant viruses. There are three subfamilies, 17 genera, and 95 species in this family. The name is derived from ''Tomato bushy stunt virus'' (TBSV). Genome All viruses in the family have a non-segmented (monopartite) linear genome, with the exception of Dianthoviruses, whose genome is bipartite. The genome is approximately 4.6–4.8kb in length, lacks a 5' cap and a poly(A) tail, and it encodes 4–6 ORFs. The polymerase encodes an amber stop codon which is the site of a readthrough event within ORF1, producing two products necessary for replication. There is no helicase encoded by the virus.
