Abstract

A distinct caulimovirus, associated with dahlia mosaic, was cloned and sequenced. The caulimovirus, tentatively designated as dahlia common mosaic virus (DCMV), had a double-stranded DNA genome of ca. 8 kb. The genome organization of DCMV was found to be typical of members of the genus Caulimovirus and consisted of six major open reading frames (ORFs), ORFs I–VI, and one minor ORF, ORF VII. Sequence comparisons with the DNA genomes of two known caulimoviruses isolated from dahlia, Dahlia mosaic virus (DMV) and an endogenous caulimovirus, DMV-D10, showed that DCMV is a member of a distinct caulimovirus species, with sequence identities among various ORFs ranging from 25 to 80%.
