Nepovirus nicotianae
Assigned virus:
• tobacco ringspot virus (TRSV)
The tobacco ringspot virus can infect solanaceous crops, cucurbits, legumes and other crops. It appears to be native in America, but is now found in many other regions. However, it is absent from most parts of Europe and under quarantine there. Symptoms depend on the type of plant infected, but stunting and deformations of leaves and fruits are common. In tobacco, ring and line patterns appear on the foliage. In soybean, the buds and leaflets become deformed and necrotic. The virus can be transmitted by the nematode Xiphinema americanum, pollen, seeds and mechanical contact.

The particles are isometric and about 28 nm in diameter. Like in other Secoviridae, the genome consists of 2 positive-sensed ssRNA molecules. RNA1 of TRSV encodes 4 non-structural proteins and RNA2 the coat protein and movement protein.
