Construction of an infectious dahlia common mosaic virus clone

Dahlia is a major ornamental plant that is cultivated worldwide. However, dahlia plants, which are mainly propagated through vegetative reproduction, are susceptible to widespread damage by viruses, and viral control requires that the nature of the infecting virus(es) be known. In this study, dahlia common mosaic virus (DCMV) was detected for the first time in Japan and sequenced. This is the first report of an infectious DCMV clone being constructed, and it will aid in the characterization of DCMV.
