Relationship of Tobacco Mosaic Virus Gene Expression to Movement Within the Plant

  • William O. Dawson


Tobacco mosaic virus (TMV) is the type member of the tobamovirus group that is characterized by 18 × 300 nm virions made up of about 2000 units of a single structural protein and one molecule of plus-sense RNA of approximately 6400 nucleotides. TMV has a wide host range and occurs throughout the world causing substantial crop losses. The virus replicates in almost every cell of the plant and accumulates to unusually high titers. Disease generally is caused by abnormal chloroplast development in infected plants resulting in leaves that are deficient in photosynthetic capacity and exhibit typical “mosaic” symptoms of light and dark green leaves.
