摘要

An elongated virus, for which the name olive vein yellow virus (OVYV) was suggested, was isolated in central Italy from a fruitless olive tree with yellowing leaf symptoms. The virus, classified as a probable member of Potexvirus, appeared to be different from other definitive or putative potexviruses. OVYV had elongated and flexuous particles, 520 nm long and 12 nm wide with striations of 3.4 nm in pitch. It was purified from Chenopodium quinoa, the only symptomatic herbaceous host, and an antiserum with a titre of 1:1024 in IEM was prepared. OVYV was serologically related to papaya mosaic potexvirus (PaMV) in IEM and to PaMV and babaco yellow mosaic virus [papaya mosaic potexvirus] in immunoblotting test. PAGE showed one protein band, only in the infected sample, with an estimated MW of 29 500 daltons. Studies are in progress to further characterize OVYV and to understand the role it plays in diseased olive plants.
