Schematic diagrams of the PRV GDFS-delgI/gE/US9/US2 strain. A Diagram of the PRV gI/gE/US9/US2 gene deletion. The transfer plasmid pSK-gIL-US2R was constructed for homologous recombination with co-transfection of two sgRNAs and PRV GDFS genome. B Identification of the plaque-purified viruses by PCR with specific primers (gIF and US2R). PRV GDFS was used as the positive control (P), and DMEM was used as the negative control (N)
