''Tobacco virtovirus 1'' is a small, icosahedral plant virus which worsens the symptoms of infection by '' Tobacco mosaic virus'' (TMV). Satellite viruses are some of the smallest possible reproducing units in nature; they achieve this by relying on both the host cell and a host virus (in this case, TMV) for the machinery necessary for them to reproduce. The entire ''Tobacco virtovirus 1'' particle consists of 60 identical copies of a single protein (CP) that make up the viral capsid (coating), and a 1063-nucleotide single-stranded RNA genome which codes for the capsid and one other protein of unknown function.

A satellite is a subviral agent that depends on the coinfection of a host cell with a helper virus for its replication. Satellites can be divided into two major classes: satellite viruses and satellite nucleic acids. Satellite viruses, which ar ...
first reported in '' Nicotiana glauca'' from southern California, U.S.. Its genome consists of linear positive-sense single-stranded RNA
Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and deoxyribonucleic acid ( DNA) are nucleic acids. Along with lipids, proteins, and carbohydra ...
