摘要: 参照GenBank中NDV的核酸序列设计一对引物,利用RT-PCR扩增F基因并得到长约1.7 kb的全基因片段,并将其构建到pMD-19T载体上。核苷酸序列测定结果表明:该基因片段全长1 662 bp,编码553个氨基酸,与Gen-Bank下载的13株参考毒株F基因比较,核苷酸和氨基酸序列同源性分别为97.2%-99.2%和96.9%-98.7%;但与LaSota、F48E9及B1等常见疫苗株的氨基酸同源性仅为88.6%-91.5%。NDV分离株F蛋白裂解位点的氨基酸序列为112R-R-Q-K-R-F-I-G119,属于基因ⅦNDV。

Abstract: One pair of primers for amplifying the F gene of NDV on GenBank were designed,withwhich the predict - ed 1. 7 kb fragment had been amplified via RT -PCR from NDV strainHebei. The 1. 7 kb fragment was inserted into pMD - 19T vector. DNA sequence analysis showed that the cloned fragment consisted of 1662 bp and coding for 553 amino acid. Compaired with 13 strainsof NDV on GenBank, neucleitide and amino acid sequence homologieswere found to be 97. 2% - 99. 2% and 96. 9% - 98. 7% respectively, but the amino acid sequence homologies to other NDV strains such as La - Sota,F48E9 and B1 were only 88. 6% - 91. 5%. The deduced amino acid sequence of the cleavage site of F protein of the NDV isolates were 112R -R -Q -K -R -F -I -G119. the NDV isolates belonged to the genetype.
