摘要
Complete genome sequence of Potato virus Y Liaoning isolate （PVY-LN） causing tobacco vein necrosis symptoms were isolated from Liaoning Province in China. Genome sequences of PVY-LN was 9 714 nucleotides in length, excluding the 3′- terminal poly （A） tail. PVY-LN encodes a single long open reading frame （ORF） of polyprotein that is predicted to be cleaved into ten mature proteins by three viral proteases. No recombination can be predicted in PVY-LN sequences compared with that of the other PVY strains using Recombination Detection Programe v. 4.16 （RDP4）. Complete genome sequence comparison and phylogenetic analysis indicated that PVY-LN is closely related to PVY necrosis strain （PVYN）.
