Torradovirus marchitezum
Assigned virus:
• tomato marchitez virus (ToMarV)
The tomato marchitez virus has been mainly reported from Central America. The symptoms on tomato plants start with small dark spots on the youngest leaves, leading to necrosis of the apical leaves. The necrosis can then descend down to the middle of the plant, but rarely includes the older leaves. Other symptoms are stunting, flower necrosis and necrotic spotting on the fruits. In tomato seedlings, nearly all plants may be infected. On chili plants, the main symptoms are yellow mosaic patterns, upward curling of the leaves, and stunting. Several other plants can be infected artificially. The virus is transmitted by whiteflies in a semi-persistent manner, but can be also transmitted mechanically (e.g. see Verbeek et al. (2014)).
The genome consists of two molecules of positive single-stranded RNA. RNA 1 is approximately 7 kb large and contains one open reading frame (ORF) that codifies a polyprotein associated with replication. RNA 2 is approximately 5 kb and has two ORFs, ORF1 encodes a protein of an unknown function, while ORF2 encodes a polyprotein consisting of the movement protein and three coat proteins.
