Abstract
A virus having tubular particles (124, 142 and 167 nm) was manually transmitted from and to Anthoxanthum odoratum (sweet vernal grass). Other experimental hosts were Chenopodium quinoa, C. amaranticolor, Zea mays, Avena sativa and Hordeum vulgare (barley); winter cultivars of barley were more often infected than spring cultivars. In tests which simulated mechanical injury, the virus was transmitted from infected to healthy A. odoratum but not to healthy barley. The virus particles, which were seen as aggregates in the cytoplasm of A. odoratum leaf cells and in anther walls, reacted strongly in immunosorbent electron microscopy tests with antisera to strains of barley stripe mosaic hordeivirus. Nevertheless, the virus could be distinguished from the Type strain of barley stripe mosaic virus by reciprocal serological tests and by symptoms in infected barley cv. Black Hulless. Using an antiserum produced against the virus, a survey of A. odoratum in the field revealed one of 72 tested plants to be naturally infected. The virus is probably that described by Catherall & Chamberlain (1980) and named anthoxanthum latent blanching virus.
