Tobacco Ringspot Virus
Nepovirus
TRSV
Host: burley tobacco (Nicotiana tabacum (burley type)
L.)
Descriptor: Symptoms
Description: Tobacco ringspot has the most distinctive symptoms of the virus diseases. The name truly describes the disease because chlorotic or necrotic rings occur in the leaf. A concentric line pattern of chlorotic and necrotic tissue, often forming an "oak leaf" pattern, is very common. The symptoms occasionally are confirmed to one side of the plant. The disease appears early in the season, usually with initial growth after transplanting. Most infected plants recover as new symptomless leaves develop. The virus is transmitted by nematodes. In the field, infected plants may appear alone or clustered. Ringspot may occur in the plant bed.
