“…In addition to DMV, it was recently shown that there are at least two more distinct caulimoviruses associated with dahlia. Tentatively referred to as Dahlia common mosaic virus (DCMV) and DMV-D10 (Pahalawatta et al, 2007;Pappu et al, 2008), these two new caulimoviruses showed significant sequence divergence compared to that of DMV (Pahalawatta et al, 2008b;Pappu et al, 2008). Both DCMV and DMV-D10 were found to be widespread based on surveys conducted in the USA and Europe (Pappu et al, 2005;Pahalawatta et al, 2007;Eid et al, 2009).…”

Selected wild Dahlia species in their natural habitats from west-central Mexico were tested for the presence of three caulimoviruses known to be associated with cultivated dahlia (Dahlia variabilis), viz. Dahlia mosaic virus (DMV), DMV-D10 and Dahlia common mosaic virus. Virus species-specific primers and PCR were used followed by cloning and sequencing of the amplicons. Results showed that the wild dahlia species in their natural habitat contained DMV-D10, which is an endogenous plant pararetrovirus. Viral sequences were found in 91% of the samples (n = 56) representing four different wild species. The gene coding for the movement protein of DMV-D10 from Dahlia coccinea and all other species was cloned and sequenced. Sequence comparisons showed divergence of this gene when compared to that of DMV-D10 from cultivated dahlias. The discovery of plant pararetroviruses in wild dahlia species in their natural habitats suggests a possible emergence, co-existence and co-evolution of pararetroviruses and their host plants.

“…DMV is a member of the genus Caulimovirus family Caulimoviridae. In addition to DMV, which was characterized at the molecular level (Richins and Shepherd, 1983), recent studies have revealed the presence of at least two more caulimoviruses, tentatively referred to as DMV-D10 and Dahlia common mosaic virus (DCMV) (Nicolaisen, 2003;Pahalawatta et al, 2008a;Pappu et al, 2008). DMV-D10 shares limited sequence similarity with known caulimoviruses, including DMV, although the genome organization clearly suggests that it is a member of Caulimovirus (Pahalawatta et al, 2008a).…”

“…Moreover, Pahalawatta et al (2008b) reported that the genome of DMV-D10 is integrated into the dahlia genome and the virus exists as an endogenous plant pararetroviral sequence (EPRV). DCMV was found to be a distinct caulimovirus species based on sequence relationships with known caulimoviruses (Pappu et al, 2008).…”

Dahlia mosaic is a serious disease affecting dahlias. In addition to the Dahlia mosaic virus (DMV) reported previously, we characterized two putative new caulimoviruses, tentatively designated as DMV-D10 and Dahlia common mosaic virus (DCMV), from dahlia. To better understand their relative incidence in dahlia, a total of 213 samples were collected during 2007 and 2008 from several varieties of cultivated dahlia (D. variabilis) in the United States. Samples were tested for the three caulimoviruses using virus-specific primers in a polymerase chain reaction. Amplicons were cloned and sequenced to confirm the infection of dahlia with these viruses. Results showed that DMV-D10 was the most prevalent (94%) followed by DCMV (48.5%) and DMV (23%). Mixed infections were common and viruses were detected irrespective of symptom expression at the time of sampling. Two percent of the samples were not infected by any of the three tested caulimoviruses. Results suggest that caulimovirus infections are widespread in dahlia and highlight the need for testing and production of virus-free material to reduce their spread.
