This is a 3D model of the tobacco mosaic virus (TMV), a positive-sense, single-stranded RNA virus belonging to the genus Tobamovirus. Known for infecting a wide variety of plants, particularly tobacco and other Solanaceae species, TMV is characterized by its rigid, rod-shaped structure. Its helical symmetry is formed by a spiral of protein subunits encasing the RNA genome, making it a model organism in the study of plant viruses and molecular biology.
