| Abstract: | Virus-infecting leaf samples of Atractylodes macrocephala Koidz. were collected from Lin′an District, Hangzhou city, Zhejiang province. Small RNA (sRNA) library construction and deep sequencing were conducted with samples holding mosaic, chlorosis and dwarf symptoms. The Cucumber mosaic virus (CMV) was specially identified in the samples after assembly of the overall sRNAs. And the complete genomic fragments of CMV (CMV-ZJAm) were verified by PCR and sanger sequencing. The results showed the 3 363 nt fragment of RNA1 sharing 99.01% nucleotide similarity with that of CMV isolate JC (CMV-JC, GenBank accession number MH594044), the 3 053 nt fragment of RNA2 sharing 99.04% similarity (CMV-JC, MH594045), the 2 217 nt RNA3 sharing 97.52% similarity (CMV isolate Anhui, KX660758). Phylogenetic analysis with complete genomic sequences indicated that CMV-ZJAm, CMV-JC, CMV-Am (CMV isolate Am, JX993910) and CMV-Anhui were clustered into one group belonging to CMV subgroup I B. In conclusion, this is the first report of CMV from A. macrocephala in Zhejiang province. |
