Abstract
Alstroemeria cv. Ovation plants with virus-like necrotic spots and streaks on leaves and petals were observed in greenhouses in Khorasan Razavi (Mashhad) and Markazi (Mahallat) provinces, Iran. Samples with virus-like symptoms reacted positively in enzyme-linked immunosorbent assay with a polyclonal antibody raised against Tomato yellow ring virus (TYRV) nucleocapsid (N) protein. TYRV-specific primers were used in a reverse transcription-polymerase chain reaction to amplify the N gene. The deduced amino acid sequences of the obtained amplicon revealed 99% identity to the N protein of an isolate of TYRV isolated from tomato (TYRV-t).
