Tymoviridae

The viruses in this family are related to the Turnip yellow mosaic virus (TYMV). They have non-enveloped isometric particles, around 30 nm in diameter, with a positive-sense, single-stranded RNA genome (containing an unusually high cytidine content). Several cause important plant diseases like TYMV or the Grapevine fleck virus. They cause mainly mosaic and mottling symptoms and are transmitted through mechanical contact and by insects.


The following genera are currently entered under this family:
