New hosts for tobacco streak ilarvirus
Tobacco streak ilarvirus (EPPO A1 organism) can naturally infect lettuce and escarole. The symptoms on escarole and lettuce include chlorosis and necrotic lesions.
In laboratory studies in Florida, US, isometric, virus-like particles were isolated from lettuce and escarole which could be identified as the bean red node strain of tobacco streak ilarvirus.
