Latest Potyviridae Stories
University of Cambridge researchers have shown that viruses use aphids as pawns, discouraging the insects from permanently settling on already-infected crops and using this forced migration to spread infection to healthy vegetation.
Turnip mosaic virus (TuMV) is a Potyvirus of the family Potyviridae which causes diseases in cruciferous plants. The virus is spread by 40-50 species of aphids in a non-persistent manner. Infected plants show symptoms such as a chlorotic local lesions, mosaic, mottling, puckering, or rugosity. Photo Copyright and Credit
Potato virus Y (PVY) is a plant pathogenic virus of the family Potyviridae. It is one of the most important plant viruses affecting potatoes. Infection results in various symptoms depending on the strain. Production loss is the most mild of the symptoms and "˜potato tuber necrotic ringspot disease' is the worst. Ringspot renders potatoes unmarketable and can therefore result in a major loss of income. Aphid vectors transmit PVY but it can also remain dormant in seed potatoes. The South...
