Barley yellow dwarf disease is one of the most important and destructive diseases in cereals in Iran. Two isolates of each predominant virus including Barley yellow dwarf virus-PAV (BYDV-PAV) and Cereal yellow dwarf virus-RPV (CYDV-RPV) were selected for sequence characterizations. The segment of PAV-IR genome (1264 nt) comprising a partial genes for coat protein (CP), read through protein (RTP) and movement protein (MP) showed a high sequence identity to PAV isolates from USA, France and Japan (96-97%). In a phylogenetic analysis it was placed into PAV group I together with PAV isolates of barley and oats. The fragment of RPV-IR (719 nt) contained partial genes for CP, RTP and MP was putatively identified as belonging to CYDV-RPV. However, RPV-IR showed a similar sequence identity with both RPV and Cereal dwarf virus-RPS (CYDV-RPS) at 90-91%, and the phylogenetic analyses suggested that it might be more closely related to RPS. These sequences are the first ones of BYD-causing viruses from Iran and Southwest Asia
