Geography-Driven Evolution of Potato Virus A Revealed by Genetic Diversity Analysis of the Complete Genome.

ABSTRACT: Potato virus A (PVA), a member of the genus Potyvirus, is an important potato pathogen that causes 30%-40% yield reduction to global potato production. Knowledge on the genetic structure and the evolutionary forces shaping the structure of this pathogen is limited but vital in developing effective management strategies. In this study, we investigated the population structure and molecular evolution of PVA by analyzing novel complete genomic sequences from Chinese isolates combined with available sequences from Europe, South America, Oceania, and North America. High nucleotide diversity was discovered among the populations studied. Pairwise F _ST values between geographical populations of PVA ranged from 0.22 to 0.46, indicating a significant spatial structure for th
