Abstract:

Lily mottle virus(LMoV)was detected in Narcissus pseudonarcissus using one set of specific primer by reverse transcription-polymerase chain reaction (RT-PCR). A 553bp DNA fragment was amplified from the sample of ‘Pink-charm’ using primers L1 (5'-TGGGCACCTTGTGAATTAC-3') and L2 (5'- TGCTGTATGCCTCTCCGTGC-3'). The primer was designed according to the published sequence of the coat protein of LMoV in the GenBank. Nucleotide sequence of the fragment(GenBank Accession No. EU167936)showed more than 98% identity with other isolates(GenBank Accession Nos.:AJ748256;AJ564636;AB053256;AF531458;AJ564637;AJ748257). Remarkably high Similarity in the nucleotide has been observed despite of their different origins. Besides, amino acid sequence of the amplified virus fragments(GenBank Accession No. ABW16938)is overlapped by the amino acid sequence of LMoV Coat protein(GenBank Accession No .NP-945145).
