Abstract：In this study，a Jiangsu isolate of pepper motle virus （PepMoV-JS）was identified from pepper plants showing leaf curling and stunting symptoms in Nanjing，Jiangsu province.Infectionof Nicotiana benthamiana by PepMoVJS resulted inleafcurling，yellowing，andsevere stunting.ThecompletegenomeofPepMoV-JS is9461bpinlength，encoding 10 mature proteins.Phylogenetic analysis revealed that PepMoV isolates were clustered into two major groups：Group I included isolates from Anhui（China），Hunan（China），Jiangsu（China）and the Republicof Korea，while GroupI comprised isolates fromthe United States，Germany，andTaiwan（China）.ChinesePepMoVisolates exhibitedlow genetic similarityandhighpopulationdiversity.NorecombinationeventsweredetectedinthegenomeofPepMoV-JS，indicatinga relativelystablegeneticstructure.The findingsof this studyprovideatheoreticalbasis forunderstanding thedistribution， evolutionary characteristics of PepMoV in China，and formulating effective control strategies.
