The tobacco mosaic satellite virus is a small icosahedral plant virus having the symptoms of an infection by tobacco mosaic virus ( English Tobacco mosaic virus , TMV, Fam. Virgaviridae , genus Tobamovirus worse). Satellite viruses are among the smallest possible replicating units in nature. They do this by using both the host cell and a host virus (in this case TMV) to get the machinery needed to multiply. The entire STMV virion (virus particle) consists of 60 identical copies of a single protein that make up the viral capsid , and a single-stranded RNA genome of 1063 nucleotides that codes for the capsid and another protein of unknown function .
