The infection does not spread through contact with insects, but instead spreads by direct contact to the neighboring cells. For its smooth entry, TMV produces a 30 k Da movement protein called P30 which enlarges the plasmodesmata. TMV most likely moves from cell-to-cell as a complex of the RNA
, P30, and replicate proteins.Class: Kingdom: Phylum: Realm:
How does tobacco mosaic virus (TMV) spread? Tobacco Mosaic Virus (TMV) Once inside the plant cell, the protein coat falls away and nucleic acid portion directs the plant cell to produce more virus nucleic acid and virus protein, disrupting the normal activity of the cell. TMV can multiply only inside a living cell but it can survive in a dormant state in dead tissue,…
How does TMV spread from plant to plant? TMV can multiply only inside a living cell but it can survive in a dormant state in dead tissue, retaining its ability to infect growing plants for years after the infected plant part died. Most other viruses die when the plant tissue dies. The most important way that TMV can be spread from plant to plant is on workers’ hands, clothing or on tools.
How to control the spread of TMV? To control the spread of TMV, farmers must: 1 dig up and destroy infected plants 2 wash their hands after handling infected plants 3 wash tools that have come into contact with infected plants in detergent or bleach 4 rotate the crops they grow in a contaminated field – they must not grow tobacco or tomato plants in the field for at least two years
Can you get TMV from smoking tobacco? When tobacco products are handled or kept in pockets, hands and clothing can become contaminated with TMV and be a source of virus. TMV is NOT spread in the smoke of burning tobacco. Symptoms vary with the species of plant infected and the environmental conditions.
How does tobacco mosaic virus (TMV) spread?
How does tobacco mosaic virus (TMV) spread from plant to plant? Tobacco Mosaic Virus (TMV) The most important way that TMV can be spread from plant to plant is on workers’ hands, clothing or on tools. This is called ‘mechanical’ transmission. When plants are handled, the tiny leaf hairs and some of the outer cells inevitably are damaged slightly and leak sap onto tools, hands, and clothing.
How does TMV spread? Smokers can spread TMV through their hands or clothes. This is because cigarettes can contain viruses from an infected tobacco plant. TMV can also be spread via contaminated tools and other gardening equipment. The tobacco mosaic virus enters new host plants via wounds.
Is tobacco mosaic virus a vector? They are not considered important vectors, however. Transmission. Tobacco mosaic virus is usually spread from plant to plant via ‘mechanical’ wounds caused by contaminated hands, clothing or tools such as pruning shears and hoes. This is because TMV occurs in very high concentrations in most plant cells.
Can you get TMV from tobacco? Yes, tobacco products can carry the virus and using them without washing your hands afterwards can potentially spread TMV. For that reason, do not use tobacco in the greenhouse or without washing your hands prior to handling plant material. Can TMV stay viable in plant debris or dead plant material?
