Tobacco mosaic virus [a] (TMV) is a positive-sense single-stranded RNA virus species in the genus Tobamovirus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves (hence the name).

Nov 13, 2024 · Tobacco mosaic virus (TMV) is a well-known plant virus from the Tobamovirus genus, particularly affecting tobacco plants, as well as other members of the Solanaceae family, including tomatoes and potatoes. TMV infection causes characteristic symptoms such as a mosaic-like mottling and discoloration of leaves, which is how the virus got its name.

Consider choosing hybrid or naturally resistant plant varieties to plant if you might be at greater risk for TMV infection. For example, many tomato or tobacco farmers have shifted to TMV resistant seeds.

Nov 21, 2023 · Tobacco mosaic virus (TMV) is named for one of the first plants in which it was found in the 1800s. However, it can infect well over 350 different species of plants. TMV is made up of a piece of nucleic acid (ribonucleic acid; RNA) and a surrounding protein coat. The complete virus is a submicroscopic, rigid, rod-shaped particle.

Oct 4, 2024 · Tobacco mosaic virus (TMV) is a disease that affects plants by causing discolouration of leaves, reduced pigment, and stunted growth. It is spread when healthy leaves touch TMV-infected plants. Insects, such as aphids, feed on sap within plant stems, reducing glucose availability and potentially leading to plant death.

Jan 10, 2024 · ToMV is a specific strain of TMV that primarily infects tomato plants. Virus particles, called virions, are rod-shaped and measure 18 x 300 nm. Each rod contains a single strand of RNA enclosed by a coat of protein. The viruses infect the plant by entering microscopic wounds in the plant cells.

Tobacco mosaic virus (TMV) is a plant virus that belongs to the genus Tobamovirus. It is named so because it majorly infects tobacco plants, potatoes, tomatoes and other members of the Solanaceae family. The infection creates a mosaic like pattern, mottling and discoloration of …

Feb 19, 2021 · Tobacco mosaic is caused by Tobacco mosaic virus (TMV), the first virus ever identified. Numerous variants (strains) of the virus have subsequently been described. TMV survives in infected plants (including viable seeds), as well as in debris from these plants. Plant-based products (most notoriously tobacco products) can harbor the virus.

Jan 14, 2025 · Tobacco Mosaic Virus (TMV) stands as a prominent model in virology, offering insights into viral structure and infection mechanisms. Its significance extends beyond plant pathology, influencing research on virus-host interactions and molecular biology.

Jan 14, 2013 · Tobacco Mosaic Virus (TMV) has a very wide host range including tobacco, vegetables (especially in the Solanaceous family), and many ornamental species. The virus is sap-transmissable and is one of the most persistent and infectious plant viruses described.
