Isolation and Characterization of a Nepo-Type Virus from Reverted Blackcurrant (Ribes nigrum L.)

Abstract

An unknown virus was isolated from a reverted blackcurrant which showed malformed flowers. A mechanically transmissible virus was purified and partially characterized. The particle size and morphology, the genome structure and the size of the coat protein found suggest that although the virus is very similar to nepovirus group, it is distinct from any other reported virus.
