Molecular Evolutionary Analysis of Potato Virus Y Infecting Potato Based on the VPg Gene.

ABSTRACT: Potato virus Y (PVY) is an important plant pathogen infecting solanaceous crops, causing significant losses to global potato and tobacco production. Some aspects of the plant pathology and molecular biology of PVY have been studied intensively, but the evolutionary dynamics of this virus are poorly understood. Here, we performed a comprehensive set of rigorous evolutionary analyses using 177 nucleotide sequences of the viral genome linked protein (VPg) gene, which interacts with the plant eukaryotic translation initiation factor 4E (eIF4E). Our Bayesian analysis reveals that the VPg gene of PVY has been evolving at a rate of 5.60 × 10^-4 subs/site/year (95% credibility interval 3.35 × 10^-4-8.17 × 10^-4), which is equivalent to those of other plant-infecting R
