Arabis mosaic nepovirus isolated from algerian iris (Iris unguicularis) imported from the Netherlands.

摘要

Arabis mosaic nepovirus (ArMV) was isolated from algerian iris (Iris unguicularis) imported from the Netherlands in 1994 under post-entry quarantine at Yokohama plant protection station in Japan. The isolated virus was sap-transmissible to herbaceous plants of 26 species in 11 families. The thermal inactivation point of the virus was 55-65鳦 (10 min.), the dilution end point was 10-3-10-5, and infectivity was retained at 20鳦 for 38-41 days. Spherical particles about 30 nm in diameter were found inpurified preparations. The molecular weight of the coat protein of the virus was about 54k. The virus reacted with the antiserum against ArMV by gel-diffusion test and was identified as ArMV. This is the first report on the isolation of ArMV from Iris spp.
