A new virus was isolated from a tomato plant from Guatemala showing necrotic spots on the bases of the leaves and chocolate-brown patches on the fruits. Structural and molecular analysis showed the virus to be clearly related to but distinct from the recently described Tomato torrado virus (ToTV) and Tomato marchitez virus (ToMarV), both members of the genus Torradovirus. The name tomato chocolàte virus is proposed for this new torradovirus. M. Verbeek and A. Dullemans contributed to this research equally. Nucleotide sequence data reported are available in the GenBank database under accession numbers FJ560489 (RNA1) and FJ560490 (RNA2).
