A: Schematic drawing of the insertion sites in the viral genome. The gray box indicates part of the viral genome. p7USC is a full-length infectious cDNA clone containing an AscI site located after the stop codon of ORF7. B and C: Construction strategy of miRNA-target sites inserted into mutants. Residues in yellow shade indicate the mutated sites as controls.
