Abstract
A mosaic disease caused by a virus with isometric particles with a diameter of 28–30 nm has been revealed on a wild vetch species Vicia unijuga in the Amur oblast. The thermal inactivation point (TIP) of the pathogen is 73°C, longevity in vitro (LIV) is up to 3 days, and dilution endpoint (DEP) is 10−5. Virions contain one capsid protein with molecular mass 19 kD. The antigenic relationship between the isolate and brome mosaic virus and earlier identified V. unijuga mosaic virus, a representative of the genus Bromovirus, is determined. The pathogen has been identified as a new strain of this bromovirus. The virus is easily transmitted to cultivated legumes, causing considerable damage.
