Phytopathology 66:954-957. A mechanically transmissable virus, which infects only graminaceous plants, caused mosaic on Guinea grass (Panicum maximum) in the Ivory Coast. The virus particles are flexuous rods 800 nm long. The virus is related serologically to pepper veinal mottle virus from the Ivory Coast and Ghana and is probably a new member of the potato virus Y group. It is named Guinea grass mosaic virus. A purification method using Triton X-100 as a clarifying agent is described. Additional key words: Panicum, potyviruses, grass viruses. |
