摘要： China rose (Rosa chinensis Jacq.) is an important ornamental plant grown widely in China. In May 2019, we sampled and analyzed a China rose plant by high-throughput sequencing using small RNAs. A luteovirus, rose spring dwarf-associated virus (RSDaV), was detected in this plant, and its complete nucleotide sequence of 5816 nucleotides was determined. The China rose isolate of RSDaV contains five major open reading frames (ORFs) and three putative small ORFs, typical of members of the genus Luteovirus. It shares 94.4% nt sequence identity with the Californian (USA) isolate of the virus. Genomic analysis revealed a deletion of a single U at nt position 5295, which introduced a frameshift mutation, and an insertion of nine nucleotides (AUAAAUGAU) at position 5706-5714, which did not change the reading frame. The aa sequence in that portion of the protein was 90.5% identical to that of the Californian isolate. This is the first report on the occurrence of RSDaV infecting rose plants in China.
