Characterization of a Virus Infecting Lisianthus.

A virus was isolated in Taiwan from imported lisianthus (Eustoma russellianum) plants bearing viruslike symptoms and was biologically, physically, and serologically characterized. Purified virions are isometric and measure 32 to 33 nm in diameter. The virus from Taiwan is morphologically similar to and serologically related to Lisianthus necrosis necrovirus (LNV) reported in Japan. This lisianthus virus does not have the same host range that was reported for LNV from Japan, but inoculation studies show that it is a strain of LNV.
