In this review, I made the phylodynamic comparisons of three plant viruses, Turnip mosaic virus (TuMV), Cauliflower mosaic virus (CaMV) and Cucumber mosaic virus (CMV), using the genomic sequences of a large numbers of isolates collected worldwide. We analyzed these genomic nucleotide sequences, in combination with published sequences, to estimate the timescale and rate of evolution of the individual genes of TuMV, CaMV and CMV. The main hosts of the viruses are Brassicaceae crops. We also compared these estimates from complete sequences with those from which non-synonymous and invariate codons had been removed. Our analyses provided a preliminary definition of the present geographical structure of three plant virus populations in the world, and showed that the time of migration of three plant viruses correlate well with agriculture history and human immigration.
