Phylogeographic History of Tomato Chlorosis Virus.

ABSTRACT: Tomato chlorosis virus (ToCV), first reported in Florida, USA, in 1998, has since emerged in multiple regions worldwide, posing a significant threat to global tomato production. However, its origin, migration patterns, and evolutionary history remain poorly understood. In this study, we used Bayesian phylogeographic analysis of coat protein gene sequences from 155 ToCV isolates to reconstruct its phylogeographic history. Our results show that ToCV evolves at a rate of 6.24 × 10^-4 subs/site/year (95% credibility interval: 4.35 × 10^-4-8.28 × 10^-4), with the most recent common ancestor dating back to 1882. The maximum clade credibility (MCC) tree revealed three major clades, with Clade 1-whose most recent common ancestor dates to approximately 1975-comprising
