Hexon protein gene of egg drop syndrome virus, named strain E05 which was isolated from breeding muscovy duck with irregular egg dropping was amplified by PCR and cloned into pMD18-T vector. The recombinant plasmids were identified by digested restriction endonuclease and PCR. The result showed that the nucleotide length of hexon protein gene encoding 910 amino acids was 2733 bp.

运用PCR技术从表现产蛋异常的种番鸭分离鉴定的减蛋综合征病毒 E05株中分段扩增六邻体蛋白基因，分别与克隆载体pMD18-T连接后，转化感受态细胞，对经PCR鉴定和酶切鉴定均为阳性的克隆进行测序，结果表明，E05株六邻体蛋白基因长度为2733 bp，共编码910个氨基酸。

In order to compare the homology of the gene encoding VP2 between MDPV-Q and MDPV which was registered in the GenBank, also in order to find out changes of the VP2 gene and the immuno-genicity between the wild-strain MDPV-Q and the attenuated strain MDPV-26 which derived by continued passage of virulent wild-type in muscovy duck embryo, a pair of primer (LHMP7/LHMP8) was designed. The upper one LHMP7 and the lower one LHMP8 corresponded to the MDPV-specific nucleotides sequence 2885-2900 and 4618-4604 respectively, according to the MDPV nucleotide sequence databases. The length of the sequence embraced by the primers was 1734bp.

为了获取这一基因片段与国外分离株进行同源性比较，同时也为了了解MDPV强、弱毒株VP2基因之间的异同关系，及其免疫原性的变化规律，通过DNA重组技术，设计了一对引物LHMP7／LHMP8，该对引物选取位于2885～2900及4618～4604的两段序列，跨幅为1734bp，并在这两条引物中分别加入两种限制性核酸内切酶SacⅡ和KpnⅠ的酶切位点，分别对MDPV-Q和由该株病毒经人工致弱后得到的MDPV-26株进行PCR扩增，并将PCR产物克隆到pMD18-T载体上，分别得到二个重组子：pMD18-T—M-Q VP2和pMD18-T-M-26 VP2。

In this paper, the complete nucleotide sequence of watermelon mosaic virus Chinese Isolate was determined. On the basis, the HC-Pro protein and CP protein both are the factors for aphid transmission were cloned and expressed in vitro, and their antiserum were prepared. By far western blot, viral receptors were identified in aphids, and their interactions were studied. The molecular mechanism of nonpersistent transmission was further elucidated.

本文完成了我国西瓜花叶病毒的基因组全序列的测定，在此基础上，克隆和体外表达了蚜传因子HC-Pro和CP蛋白，制备了相应抗体，利用Far western blot技术鉴定了其蚜虫体内的受体蛋白，并对三者互作关系进行研究，进一步阐明了非持久性传毒的分子机制。
