Abstract: Plant RNA viruses are characterized by extreme evolutionary capacities that allow them to successfully expand their distribution ranges rapidly and cause serious harm to their host. Studies on the genetic evolutionary history of plant RNA virus population help to provide the information essential for designing strategies for viruses controlling. In recent years, it has been confirmed that plant RNA viruses change their genomes with gene mutation or gene recombination rapidly to form a quasispecies which is a cloud of diverse variants that are genetically linked through mutation. Plant RNA viruses are known to face many narrow genetic bottlenecks and a significant percentage of a population is prevented from reproducing during their life cycles , including the cell-to-cell movements , infecting the plant systemically,being transmitted from plant to plant. Genetic bottlenecks can lead to genetic drift or natural selection for the different genome. The genetic structure of plant RNA viruses population alsonare influenced by gene flow.
