Lettuce necrotic yellows virus (LNYV) causes severe disease and crop losses to lettuce in Australia and New Zealand. It has distinct bacilliform particles that mature in the cytoplasm of infected plant cells and a single-stranded, negative-sense RNA genome encoding for six viral proteins. The epidemiology of this Cytorhabdovirus has been extensively studied. LNYV has a limited recognized geographical range, and narrow host range, though has been found to naturally infect both dicots and monocots. Control measures emphasize weed management and aphid control, to limit the introduction of the virus into lettuce crops.
