Abstract: During 2018 to 2019,pepper plants showed typical symptoms of dwarf,yellowing,curling,chlorosis and rolling up of leaves were found in Kashgar,Xinjiang Uygur Autonomous region. To identify the virus that causing pepper virus disease,total RNA was isolated from the diseased tissues with typical virus symptoms,and reverse transcription(RT)-PCR assays were performed with specific primers for Cucumber mosaic virus (CMV)and Pepper mild mottle virus (PMMoV). The expected 735 bp CMV and 472 bp PMMoV fragments were amplified from diseased pepper tissue samples,respectively. Sequence analysis showed 95%,99% similarity with that of CMV(South Korea,GU327368.1)and PMMoV(Japan,AB276030.1),respectively. The results showed that pepper plants were co-infected by CMV and PMMoV in Kashgar,Xinjiang region.
