“…In fact, VP1, VP4, 3D, 2B, 5′NCR, VPg, or 3′NCR have been previously selected as RNAi target genes [6], [12], [13], [14], [15], [16], [17], [18]. If there are conserved regions of viral genes among different serotypes of FMDV, the viral genes could be screen as RNAi targets, so we choose RNAi-VP2, RNAi-VP3, RNAi-VP4 as target site in this study.…”
