Abstract:

In order to explore the pathogenesis of subgroup J avian leukosis virus(ALV-J), a full-length infectious clone of ALV-J (pSK-AH-J11) was constructed by combining of four fragments using PCR method from AH-J11 isolated from broiler in Anhui province, then the complete genome was cloned into pBluescript SK(+) vector. The recombinant plasmid pBl-AH-J11 was transfected into chicken embryo fibroblast (CEF) cells and the recombinant ALV-J was rescued. The rescued ALV-J (rALV-J) was identified by RT-PCR, Western blot, indirect immunofluorescence assay and sequence comparision of gp85 gene with AH-J11strain, respectively. The results showed that the recombinant rALV-J was rescued in CEF. This study provides a useful platform for investigation of the pathogenesis and molecular biology of ALV-J.
