Abstract

From wild plant Chenopodium hybridum L., which had yellow flecking and severe mosaic, a isolate of sowbane mosaic virus (SoMV) was isolated. The virus isolate was identified on the basis of test plants, serology, electron microscopy and properties in vitro. Nicotiana benthamiana proved to be a new symptomless host of SoMV. The virus reacted with the antisera to the American (A) and Yugoslavian (J) isolates of SoMV and it could not be distinguishable from them. Isometric virus particles, c. 30 nm were found in partially purified preparations of SoMV-H. The thermal inactivation point was 88-degrees-C, the dilution end-point 10(-6) and the longevity in vitro 24 days. This is the first report of the natural occurrence of SoMV in Chenopodium hybridum.
