Abstract
Arabis mosaic virus (ArMV) is a virus with a wide host range. In this study, the genetic diversity of ArMV and the molecular mechanisms underlying its evolution were investigated using the coat protein (CP) sequence. Of the 33 ArMV isolates studied, three were found to be recombinants. The other 30 recombination-free ArMV isolates could be separated into two major lineages with a significant F
ST value (0.384) and tended to cluster according to their geographical origin. Different evolutionary constraints were detected for the two linages, pointing to a role of natural selection in the differentiation of ArMV.
