Characterization of a new carmovirus isolated from an Adonis plant

Abstract

An isometric virus was isolated from a cultivated Adonis plant (A. ramosa). The purified virus particle is 28 nm in diameter and is composed of a single coat protein and a single RNA genome of 3,991 nucleotides. Sequence analysis showed that the virus is closely related to carnation mottle virus. The virus was used to mechanically infect healthy A. ramosa plants, resulting in mosaic and leaf curl symptoms; however, attempts to inoculate carnation plants did not result in infection. We propose the virus as a new carmovirus and have named it adonis mosaic virus (AdMV).

“…Japanese iris necrotic ring virus (genus Betacarmovirus) was discovered in 1982 (Takemoto et al 2000). Adonis mosaic virus (genus Alphacarmovirus) was discovered in 2017 (Yasaki et al 2017). Soybean dwarf virus (SbDV, genus Luteovirus) was discovered in 1968 and characterized (Tamada et al 1969;Terauchi et al 2001).…”
