Beschreibungen/Notizen
A distinct sobemovirus was isolated from diseased
Artemisia annua
plants grown in experimental culture plots in Switzerland. Electron microscopy performed on extracts of leaf and root samples of a diseased
A. annua
plant revealed icosahedral-30 nm viral particles. The complete nucleotide sequence of the viral genome was determined. The single positive-strand RNA of 4138 nt encodes four open reading frames with an organization similar to that described for sobemoviruses. Phylogenetic analysis revealed a close relationship to ryegrass mottle virus. The virus was efficiently acquired by healthy
A. annua
from contaminated soil samples. “Artemisia virus A” is tentatively proposed as a name for this new candidate member of the unassigned genus
Sobemovirus.
