摘    要:根据GenBank中报道的NDV融合蛋白基因(F)序列,设计了一对特异性引物,用该引物对所分离的LN-SN株进行了RT-PCR扩增;将扩增得到的PCR片段纯化后与pGEM-T连接得到重组质粒pGEM-F,用于核苷酸序列测定。结果该基因ORF长1662bp,编码553个氨基酸;将LN-SN毒株与GenBank中已报道的NDV毒株进行比较,F基因核苷酸序列的同源性在83.1%~98.9%之间,推导的F蛋白氨基酸序列的同源性在88.1%~99.5%之间。

关 键 词:新城疫病毒  融合蛋白基因  遗传变异

Abstract:According to fusion protein gene sequence of Newcastle Disease virus strain reported by GenBank database,a pair of specific primers was designed and used to amplify F gene of LN-SN strain.The positive PCR product was purified and ligatured with pGEM-T.The correct positive recombinant was used for sequencing.The open reading frame length of F gene of LN-SN strain was 1662bp and encoded 553 amino acids.The homology of nucleic acid and amino acid among the strains of NDV accessed by GenBank database ranged from 83.1 to 98.9% and from 88.1 to 99.5% ?
Keywords:Newcastle Disease virus  fusion protein gene  Heredity and Variation
