title: Evidence for presence of types A and B of beet necrotic yellow vein virus (BNYVV) in Iran.
abstract: Rhizomania a viral disease, caused by beet necrotic yellow vein benyvirus (BNYVV), is now widely spread, throughout the sugar beet growing areas of Iran. Genomes of BNYVV are composed of five RNA molecules with specific functions. In this study sequence analyses were conducted on the major coat protein gene (CP21), and parts of RNA3 and RNA4 of an Iranian strain of BNYVV from the Fars province. Sequence alignments of Iran Fars CP21 with other isolates showed closed similarities at nucleotide and amino acid levels with BNYVV pathotype A isolates; S from Japan, and YU2 from Yugoslavia. These results suggest that Iran-Fars isolate probably originated from Asia or neighboring European countries rather than from Germany or France.
