Abstract: In order to rescue the env element-substitution virus, we constructed the recombinant plasmid pNX-HNenv that contained the whole myelomas strain ALV-J NX0101 genome, but with env element of hemangiomas strain ALV-J HN06. The plasmids were transfected into DF-1 cells and the rescued viruses were identified, respectively. The recombinant virus was stable in cell culture during nine passages, and could be identified by ALV-J specific monoclonal antibody JE9 and virus NX-HNenv was rescued. The results showed that the env substitution had no apparent influence on ALV-J virus rescue, virus entry and replication.

Key words: subgroup J avian leukosis virus; env gene; reversegenetics; replication
