A slightly flexous virus, 470-500nm, caused necrosis in the edible lily (Lilium leichtlinii var. maximowiczii Baker) when associated with Tulip breaking virus (TBV) in Hokkaido, Japan. The virus infected 11 of 43 plant species belonging to 10 families inoculated with sap. The thermal inactivation point of the virus was 55-60°C for 10min, and its dilution end point ranged between 10-5 and 10-6. Moreover, the virus longevity in vitro was 15 days at 20°C. The molecular weight of proteins for the virus was determined to be 24, 000-25, 000 daltons by SDS-polyacrylamide gel electrophoresis. The virus also reacted positively with antiserum against Lily virus X from the Netherlands. These results identified the virus as Lily virus X.
