Ornithogalum mosaic virus (OrMV) occurred in Akita Prefecture. An OrMV isolate obtained from a diseased
O. thyrsoides could infect not only O. thyrsoides and O. dubium but also five dicot plants (
Nicotiana clevelandii,
Gomphrena globosa,
Chenopodium amaranticolor, C. quinoa and
Tetragonia tetragonoides). Another isolate from a diseased
O. dubium, by contrast, was transmissible via sap inoculation to the two
Ornithogalum plants but not to any dicot plants tested. The two isolates caused mosaic symptoms on the two
Ornithogalum plants. This is the first report on the occurrence of OrMV in Japan.
