Potato Virus Y (Potyvirus PVY ) on burley tobacco (Nicotiana tabacum (burley type)) - 1440040

Potato Virus Y
Potyvirus PVY

Host: burley tobacco (Nicotiana tabacum (burley type) L.)
Descriptor: Symptoms
Description: The initial symptom of PVY infection is vein clearing on newly developing leaves. The extent of the vein clearing is intermediate between that caused by TEV and TVMV. Leaves then develop a faint mottling and the characteristic vein banding: dark green bands along the veins with lighter green tissue adjacent. The pattern is more regular than that caused by TVMV. Veinlets and veins may become necrotic on plants infected with severe strains of PVY. This Virus is transmitted from vegetables and weeds to tobacco by migrating aphids.
