Identification of an intergenic region that is not essential for replication of goatpox virus

摘要

A recombinant goatpox virus was constructed in which an enhanced green fluorescent protein gene was inserted under the control of the 11K late promoter, a guanine phosphoribosyltransferase gene was inserted under the control of the 7.5K early/late promoter, and exogenous genes were inserted into an intergenic region between loci gp_24 and gp_24.5 of the recombinant genome. Analysis of protein expression showed that LT cells infected with only the recombinant virus produced specific fluorescence. A comparative growth assay demonstrated the stability of the recombinant virus at the replication level. These results suggest that the intergenic region is not essential for replication of goatpox virus.
