What is Tobacco Mosaic Virus (TMV)?

Author:

Tobacco mosaic virus (TMV) is a rigid rod-shaped ssRNA-containing virus that causes distortion and blistering of leaves in a wide range of plants. Tobacco mosaic virus (TMV) is a positive-sense single stranded RNA virus 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). The single‐stranded ribonucleic acid (ssRNA) phages are small icosahedral viruses which infect their host via F‐ or polar pili.
