Complete genome sequence of a dahlia common mosaic virus isolate from New Zealand.

ABSTRACT

Dahlia mosaic disease of the ornamental flowering plant Dahlia is caused by two caulimoviruses, dahlia mosaic virus (DMV) and dahlia common mosaic virus (DCMV). We used a rolling-circle amplification method to amplify, clone and determine for the first time the full genome sequence of a DCMV isolate from New Zealand (DCMV-NZ). Within the 7949-bp circular double-stranded retro-transcribing DCMV-NZ DNA, we identified six putative open reading frames, typical of all genomes in the family Caulimoviridae. The availability of the complete DCMV sequence provides a reference genome against which all others can be compared.
