Detection of expression patterns of BmCPV-miRNAs and target gene BmRan in the midgut of silkworm larvae infected with BmCPV. (A) BmCPV-miR-1 and BmCPV-miR-3 detected by stem-loop RT-PCR. The bands sized about 70–80 bps were the putative miRNAs. c: control; t: BmCPV infected; t1: BmCPV-miR-1; t2: BmCPV-miR-3. (B) Expression pattern of BmCPV-miR-1. (C) Expression pattern of BmCPV-miR-3. (D) Expression pattern of BmRan with normalization to different internal reference genes. The expression of BmCPV-miRNAs gradually increased, while the expression of the target gene BmRan gradually decreased, as the infection advanced (n = 3 replicate samples, each containing five larvae).
