摘要：

The sequence of the 3'-terminal 1492 nucleotides of the genome of a New Zealand isolate of clover yellow vein potyvirus (CYVV) has been determined. This sequence encodes a large open reading frame of 1314 nucleotides, the start of which was not identified, but which encodes a putative 272 amino acid coat protein. Downstream of the coat protein coding region is a 177 nucleotide untranslated sequence terminated by a polyadenylate tract. Comparison of the deduced CYVV-NZ coat protein amino acid sequence with two other strains of CYVV showed 86-93% similarity, suggesting CYVV-NZ should be regarded as a separate CYVV strain. CYVV-NZ shares with other CYVV strains a direct repeat of 14-16 nucleotides that is capable of forming a stem-loop structure. Examination of 35 strains of 15 other potyviruses showed a similar stem-loop structure conserved in all cases. A possible role in replication is hypothesized for the structure.
