Molecular characterization of artemisia virus A, a new sobemovirus isolated from Artemisia annua

Molecular characterization of artemisia virus A, a new sobemovirus isolated from Artemisia annua 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

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.
