中文摘要In the present study, Rana grylio virus (RGV, an iridovirus) thymidine kinase (TK) gene and viral envelope protein 53R gene were chosen as targets for foreign gene insertion. Delta TK-RGV and Delta 53R-RGV, two recombinant RGV, expressing enhanced green fluorescence protein (EGFP) were constructed and analyzed in Epithelioma papulosum cyprinid (EPC) cells. The EGFP gene which fused to the virus major capsid protein (MCP) promoter p50 was inserted into TK and 53R gene loci of RGV, respectively. Cells infected with these two recombinant viruses not only displayed plaques, but also emitted strong green fluorescence under fluorescence microscope, providing a simple method for selection and purification of recombinant viruses. Delta TK-RGV was purified by seven successive rounds of plaque isolation and could be stably propagated in EPC cells. All of the plaques produced by the purified recombinant virus emitted green fluorescence. However, Delta 53R-RGV was hard to be purified even through twenty rounds of plaque isolation. The purified recombinant virus Delta TK-RGV was verified by PCR analysis and Western blotting. These results showed EGFP was expressed in Delta TK-RGV infected cells. Furthermore, one-step growth curves and electron microscopy revealed that infection with recombinant Delta TK-RGV and wild-type RGV are similar. Therefore, RGV was demonstrated could be as a viral vector for foreign gene expression in fish cells. Crown Copyright (C) 2011 Published by Elsevier B.V. All rights reserved.
