By passing juice from chrysanthemum leaves with mosaic or mottle symptom through a Sepharose 2B gel filtration column, fractions which gave infections on Chenopodium amaranticolor, zinnia, tobacco (Samsun NN and Bright Yellow) and Nicotiana glutionsa were recovered, whereas the unfiltrated juice was noninfectious. This recovery of fraction with infectivity was due to the elimination of several inhibitors in chrysanthemum by the chromatography.
