Abstract
A virus associated with yellow-to-purple ringspot on honeysuckle plants has been detected and tentatively named honeysuckle ringspot virus (HnRSV). The complete nucleotide sequence of HnRSV from infected honeysuckle has been determined. The genomic RNA of HnRSV is 3,956 nucleotides in length and is predicted to contain five open reading frames (ORFs). Comparisons of the amino acid sequences of the ORFs of HnRSV with those of members of the family Tombusviridae show that HnRSV is closely related to members of the genus Carmovirus. Phylogenetic analysis based on the amino acid sequences of RdRp and coat protein and nucleotide sequences of the whole genome revealed that HnRSV forms a subgroup with the carmoviruses. Together, our results support the classification of HnRSV as a member of a new species in the genus Carmovirus, family Tombusviridae.
