The complete sequence of GF_YL20, a potato virus Y (PVY) isolate from China, encodes a polyprotein of 3,061 amino acids. Sequence analysis indicates that GF_YL20 has a genomic structure different from previously reported PVY strains. It shares 99 % nucleotide sequence identity with PB209 (PVY(N:O)) except in VPg, but more than 97 % nucleotide sequence identity with the VPg of Mont (PVY(N)), PB312 (PVY(NTN)) and HN2 (SYR-I). Phylogenetic analysis indicates that GF_YL20 is a novel N:O recombinant with three recombination breakpoints.
GF_YL20是一种来自中国的马铃薯Y病毒（PVY）分离株，其完整序列编码一个由3061个氨基酸组成的多聚蛋白。序列分析表明，GF_YL20的基因组结构与先前报道的PVY株系不同。除VPg外，它与PB209（PVY(N:O)）的核苷酸序列同一性为99%，但与Mont（PVY(N)）、PB312（PVY(NTN)）和HN2（SYR-I）的VPg核苷酸序列同一性超过97%。系统发育分析表明，GF_YL20是一种具有三个重组断点的新型N:O重组体。
