“…Symptoms of DVS include pale-green or orange streaks, blotches, and chlorotic mosaic on the leaves, as well as a severe reduction in flower size and color, leaf curling, defoliation during autumn and winter, and death of single limbs or whole plants (Forster and Milne 1975). Infection usually occurs between spring and summer and has been transmitted through aphid hosts carrying the virus (Forster and Milne 1978). Note: Disease rating based on a score (0%-100%) where 0% = healthy and 100% = fully diseased/dead plants.…”

Daphne (Daphne laureola L.) is a perennial evergreen shrub native to Eurasia and northern Africa. Introduced to North America as an ornamental shrub, the plant has readily absconded gardens and can now be found throughout suitable habitats on both the east and west coasts of the continent. In Canada, daphne has naturalized in southwestern British Columbia including Vancouver, southern Vancouver Island, and the Gulf Islands. Daphne is of particular concern to the endangered Garry oak (Quercus garryana Douglas ex Hook.) because it invades shady woodland areas, forming dense mono-specific stands that can suppress and inhibit native vegetation. The berries and all other parts of the daphne plant contain a mixture of toxic chemicals that can be fatal to humans or animals if ingested. Removal teams suggest using gloves for elimination and handling of daphne because of its corrosive sap and oil. Widespread planting combined with a lack of public knowledge regarding the species' invasiveness has created great concern over its potential to spread. Various methods of control (chemical, manual, and biological) have been developed. The most commonly applied approach in Canada is manual control, but care must be taken to avoid contact with skin and follow-up monitoring and control is advised. A promising biocontrol agent is the fungus Phomopsis sp. denovo, which has been observed to cause high levels of mortality in D. laureola under both laboratory and field conditions.

“…DVS is transmitted by an aphid species, Myzus persicae (Sulz. ), but the rate of transmission of the virus is increased by grafting (Foster and Milne 1978). DVS was reported to be the most common virus found infecting daphne plants in New Zealand in 1975 (Foster andMilne 1975).…”

Summary Daphne virus S (DVS), a member of the genus Carlavirus, was isolated from a daphne plant in Japan. The genome of the isolate (DVS-JP) consisted of 8736 nucleotides and was predicted to contain six open reading frames (ORFs). The overall genome sequence identity between DVS-JP and the previously reported Korean isolate of DVS (DVS-K) was 83.0%, whereas identities to other carlaviruses ranged from 20.5-56.0%. Each DVS-JP ORF shared more than 80% identity at both the nucleotide and amino acid levels with DVS-K, but less than 56% with other carlaviruses, which confirmed that DVS-JP was the same species as DVS-K. The RNA dependent RNA polymerase (RdRp) showed the highest identity with Phlox virus S, and the coat protein (CP) showed the highest identity with Helenium virus S and Chrysanthemum virus B. The genome sequence of an isolate of DVS-JP revealed a high degree of identity with DVS-K, which increases our understanding of the evolution of the genus Carlavirus.
