'''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]] ''Lettuce big-vein associated virus'', which is transmitted by the obligately [[parasit]]ic soil-inhabiting [[fungus]], ''[[Olpidium brassicae]]''. However, in 2000 a second virus ''[[Mirafiori lettuce virus]]'' was found in lettuce showing big-vein symptoms. Furthermore, since the lettuce infected with this virus alone developed big-vein symptoms, it is considered to be a main agent of the big-vein disease.
