摘要： Analysis of a loquat tree with leaf curl symptoms by deep sequencing revealed a novel virus with a single-stranded RNA genome, for which the name "loquat virus A" (LoVA) was proposed. The complete genome sequence comprised 7553 nucleotides (nt) and an additional poly(A) tail at the 3 ' terminus. Sequence comparisons of LoVA showed moderate similarity to cherry virus A (CVA), currant virus A (CuVA), and mume virus A (MuVA), which are members of the genus Capillovirus in the family Betaflexiviridae. Phylogenetic analysis of the full-genome nt sequence and replicase-like protein supported the placement of LoVA within the genus Capillovirus. However, it has a distinct genome organization, differing from recognized capilloviruses, as it contains three open reading frames (ORFs), with the coat protein (CP) expressed separately from the replication-associated protein (RP) rather than being encoded in the same ORF. This indicates that LoVA is a novel member of the genus Capillovirus in the family Betaflexiviridae with a distinct genomic organization.
