A novel Potato virus Y (PVY) isolate, L26, recovered from a Frontier potato line was initially typed as a PVY(NTN) strain using multiplex RT-PCR and serological assays. However, L26 induced mosaic and mild vein clearing symptoms in tobacco rather than vein necrosis characteristic of the PVY (NTN) strain. The whole genome sequence was determined for L26 and two other PVY(NTN) isolates, HR1 and N4, from Idaho that did induce vein necrosis in tobacco. The sequence of all three isolates was similar… CONTINUE READING
