Based on PDB code 6SAE, this is the structure of tobacco mosaic virus (TMV), a plant virus and member of the RNA tobamovirus family. TMV was the first ever virus to be discovered and is an important structure in the history of virus biology, revealing how viruses form geometric structures to enclose and protect their genomes. TMV forms a spiral-shaped cylinder of 2130 subunits that encircles the single-strand RNA genome.
We have made two differently-coloured models of TMV. Each model shows seven complete rings of TMV, with subunits in alternating colours (green-blue or green-yellow) to help illustrate how these lock and stack together to form overlapping layers. These two 6.5 cm models are 3.6 million times larger than the 18 nm diameter of the viral cylinder and each comes with a removable display stand.
Alongside each TMV model, there is the option of an enlarged version of two individual subunits (blue and grey). This additional pair of subunits fit together to show more detail of how a TMV ring starts to form. At 4 cm long, these are 2.5 times the size of the subunits in the main TMV model.
