These methods enabled almost complete removal of carnation mottle virus (CarMV) particles present in the plant material. The purified particles had an unusual ultraviolet absorption spectrum (A260/280 = 1.53), contained about 5% RNA (estimated from a buoyant density p = 1.325 in CsCl), with an extinction coefficient of E 0.1%260=2.27. The molecular weight of the coat protein subunit was about 23,500. In the serological ring precipitin test, CYFV antiserum had a titer of 1/256 and 1/8 against dissociated virus (CYFV-D) in the gel diffusion tests. The antisera did not react with extracts from healthy plants nor with those from plants infected with CarMV, carnation etched ring, and carnation vein mottle viruses.
