This work reports the discovery and the complete genome sequence of a novel member of the genus Badnavirus in the family Caulimoviridae from a Chinese jujube tree of known variety which grown in Aksu, Xinjiang, China. The symptoms of jujube leaves infected by the virus showed mosaic and malformation, and round chlorotic spots on infected fruits. The genome of this virus is a circular double-stranded DNA, which has the length of 7086 nt and has a genome structure similar to the one reported for jujube mosaic-associated virus (JuMaV), with five open reading frames (ORFs). High nucleotide and amino acid sequence similarity were seen between JuMaV and the new virus, and the nucleotide (NT) difference of the genome was greater than 20% in the RT/ Rnase H coding region of ORF3. Consequently, the virus was identified a new variant of JuMaV, and propose the name as jujube mosaic-associated virus A (JuMaVA). |
