The virus in naturally infected, stunted Chinese mallow plants and mosaic leaves was identified as Cucumber mosaic virus ( CMV ). Six symptomatic plants and one symptomless plant were collected in Chongqing, China. DAS ‐ ELISA suggested CMV was likely associated with the diseased Chinese mallow. Double‐stranded RNA was extracted from the samples, analysed by RT ‐ PCR , and the coding sequences of their coat proteins ( CP s) were sequenced. The results further confirmed CMV was the pathogen causing Chinese mallow stunted, mosaic disease. The isolate was named CMV ‐ DXC . The full sequence of CMV ‐ DXC CP was determined, and it had the highest nucleotide identity (99.4%) of those of CMV ‐lily, CMV ‐ WSJ and CMV ‐Hnt, respectively. Phylogenetic analysis shows that CMV ‐ DXC belongs to CMV subgroup II . To our knowledge, this is the first report of CMV infecting Chinese mallow in China.
