title: Geographically driven adaptation of chilli veinal mottle virus revealed by genetic diversity analysis of the coat protein gene.
abstract: Chilli veinal mottle virus (ChiVMV) is an important plant pathogen with a wide host range. The genetic structure of ChiVMV was investigated by analyzing the coat protein (CP) genes of 87 ChiVMV isolates from seven Asian regions. Pairwise F ST values between ChiVMV populations ranged from 0.108 to 0.681, indicating a significant spatial structure for this pathogen. In phylogeny-trait association analysis, the viral isolates from the same region tended to group together, showing a distinct geographic feature. These results suggest that geographic driven adaptation may be an important determinant of the genetic diversity of ChiVMV.
