Varicosavirus lactucae

Assigned virus:
lettuce big vein-associated virus (LBVaV)

The lettuce big vein-associated virus is widely distributed and causes the big vein disease on lettuce, it also infects other plants. The symptoms are the striking chlorophyll clearance around the veins, crinkled leaves and a reduced head size, which is often oblong in shape. It is transmitted by the fungus Olpidium brassicae which infect the roots and might form resting spores that persist in the soil for several years (e.g. see Maccarone, 2013).

On tobacco a closely related virus, 'tobacco stunt virus' has been described, which is now regarded as a strain of LBVaV (Sasaya et al., 2005).
