RESUMEN Potato virus Y (PVY) is one of the most severe viruses affecting the production of potato (Solanum tuberosum) in the world. This study presents a detailed molecular analysis using nextgeneration sequencing (NGS), IC-RT-qPCR and RT-PCR on the PVY isolates infecting seed-tubers and foliage of potato plants cv. Diacol-Capiro in La Union (Antioquia, Colombia). Analysis of incidence by IC-RT...

BACKGROUND Potato virus Y (PVY, genus Potyvirus) causes substantial economic losses in solanaceous plants. Routine screening for PVY is an essential part of seed potato certification, and serological assays are often used. The commercial, commonly used monoclonal antibodies, MAb1128, MAb1129, and MAb1130, recognize the viral coat protein (CP) of PVY and distinguish PVYN strains from PVYO and PV...

Potato Virus Y (PVY) is a member of the Potyviridae family – the largest plant virus family. PVY infects Solanaceae – agriculturally important species such as tobacco, potato, pepper, tomato This pathogen causes decrease in yield and quality. PVY isolates have been divided into three main strains: PVYN, PVYO and PVYC, according to the symptoms induced on tobacco and potato. PVYN isolates can be...
