The 3′ UTR is essential for viral genome replication. (A) 0.8 μg of the in vitro transcribed products of pR-DHAV-1 or pR-DHAV-Δ3′UTR-A25 were transfected into DEFs, cell lysates were collected from 12 to 60 hpt and viral copy number was measured by RT-qPCR. (B) Equal amount of in vitro transcribed product of pR-DHAV-1 or pR-DHAV-R3′UTR-A25 were transfected into DEFs, cell lysates were collected at 4 hpt to measure the remaining amount of viral RNAs. (C) Equal amount of 0.8 μg of the in vitro transcribed products of pR-DHAV-1 or pR-DHAV-R3′UTR-A25 were transfected into DEFs to measure viral growth characteristics as previously described. Bars represent the means ± standard deviations of three replicate experiments.
