摘 要：Odontoglossum ringspot virus(ORSV) is a member of the genus *** is one of the most prevalent viruses infecting orchids *** studies reported the genetic variability of ORSV isolates from Korea and ***,the evolutionary rate,timescale and phylogeographical analyses of ORSV were ***-one CP gene sequences of ORSV were determined in this study,and used them together with 145 CP sequences obtained from GenBank to infer the genetic diversities,evolutionary rate,timescale and migration of ORSV *** rate of ORSV populations was 1.25 x 10 nt/site/*** most recent common ancestors(TMRCAs) came from 30(95% CIs,26-40) year *** on CP gene,ORSV migrated from China’s mainland and South Korea to Taiwan island,Germany,Australia,Singapore,and Indonesia,and it also circulated within east *** study is the first attempt to evaluate the evolutionary rates,timescales and migration dynamics of ORSV.
