Abstract:
The purpose of this study is to elucidate the molecular mechanism of one-way serological reaction between XJ-160 virus and SINV by recombinant viruses which exchanged the glycoprotein genes individually or simultaneously. Three recombinant viruses were obtained based on the whole-length infectious cDNA clone of XJ-160 virus. The infectivity and pathogenesis to BHK-21 cells and animals were studied and the gene which controlled this one-way serological reaction phenomenon was searched by MCPENT. The results showed that the E2 glycoprotein was the main factor which influenced the growth rate, plaque morphology and pathogenicity of BHK-21 cells and suckling mice. The results of MCPENT showed that the E2 glycoprotein of SINV played a major role in this one-way serological reaction phenomenon. Our study identified the SINE2 gene was the determined gene for one way serological reaction between XJ-160 virus and SINV, and this research laid the foundation for further analysis of the genomic structure and function of SINV.
