SOME PROPERTIES OF APPLE MOSAIC VIRUS ISOLATED FROM THIMBLEBERRY IN BRITISH COLUMBIA

A group of native thimbleberry (Rubus parviflorus) in British Columbia with virus-like symptoms was found to contain an ilarvirus which was mechanically transmitted to cucumber and Chenopodium quinoa. The virus consists of a single coat protein species of M_r 30 000 and four RNA species of M_r 1.18 x 10⁶, 0.99 x 10⁶, 0.72 x 10⁶ and 0.34 x 10⁶. Virus particles sediment in sucrose density gradients as two major peaks of 82S and 100S and have a buoyant density in cesium chloride of 1.326. Polyclonal and monoclonal antibodies were prepared against the virus and, in serological tests, the thimbleberry virus was identified as a strain of apple mosaic virus.
