Characterization of a new Anulavirus isolated from Amazon lily plants.

A quasi-spherical virus was isolated from a cultivated Amazon lily plant (Eucharis grandiflora) that could be mechanically transmitted to healthy E. grandiflora plants, subsequently producing mild mosaic or mottle symptoms on the leaves. The purified virus consisted of three quasi-spherical particles about 20 nm wide and 70, 40 and 30 nm in length, containing three segmented genomes of 3,169, 2,507 and 2,530 nucleotides, respectively. Sequence analysis showed that the newly isolated virus is related to pelargonium zonate spot virus, a member of the genus Anulavirus. We propose that the virus should be designated as Amazon lily mild mottle virus (ALiMMV).
