Lettuce big-vein disease causes leaf distortion and ruffling in affected lettuce plants.
This disease was first associated in 1983 with a rod-shaped virus named lettuce big-vein associated virus (LBVaV), which is transmitted by the obligately parasitic soil-inhabiting fungus, Olpidium brassicae.[1] However, in 2000, a second virus, Mirafiori lettuce big-vein virus (MLBVV), was found in lettuce showing big-vein symptoms. Furthermore, since the lettuce infected with LBVaV alone doesn't develop the symptoms while the infected with MLBVV one does, the latter virus is considered to be a main agent of the big-vein disease.[2]
