Abstract

A new virus was detected in common fleabane (Erigeron annuus) showing virus-like symptoms including leaf yellowing, mosaic, and mottling. This virus is tentatively named "fleabane yellow mosaic virus" (FbYMV). The complete genome sequence consists of two RNA segments of 7,133 nt (RNA 1) and 4,810 nt (RNA 2), excluding the poly(A) tract. Sequence analysis showed a genome organization comparable to that of members of the genus Torradovirus. The level of sequence identity between FbYMV and known members of the genus Torradovirus was below the cutoff established by the ICTV for species demarcation. Therefore, FbYMV should be classified as a new member of the genus Torradovirus.
