Abstract

Beet necrotic yellow vein virus (BNYVV), the type member of the Benyvirus genus, has a multipartite, positive-sense single-stranded RNA genome, which consists generally of four, or in some isolates five, distinct RNA species. In this study, 108 BNYVV infected soil samples were collected from Isparta province, Turkey. Sugar beet plants cv Kasandra were grown in these soil samples using bait plant techniques and root samples were then analyzed by dsRNA analysis. The RNA was purified by CF-11 cellulose chromatography and gel electrophoresis. In 108 samples tested, dsRNA profiles were observed in 53 samples. No dsRNA bands were observed in negative control used in the analysis.
