Does Tmv Have an Envelope?

TMV is the type member of a large group of viruses within the genus Tobamovirus. The rod-shaped virus particles (virions) of TMV measure about 300 nm x 15 nm (Figure 6). A single TMV particle is composed of 2,130 copies of the coat protein (CP) that envelope the RNA molecule of about 6,400 nucleotides (Figure 7).

Is TMV enveloped or non-enveloped?

A helical capsid forms the shape of tobacco mosaic virus (TMV), a naked helical virus, and Ebola virus, an enveloped helical virus. The capsid is cylindrical or rod shaped, with the genome fitting just inside the length of the capsid.

What is the structure of TMV?

TMV was the first virus to ever be discovered. It is composed of 2130 identical coat protein subunits following the right-handed helix of an accompanying RNA strand to produce a 300 nm hollow cylinder with an outer diameter of 18 nm and a 4 nm wide central channel.
