Sense and antisense transcripts of silkworm miRNAs. (A) Hairpin structures of the sense and antisense sequences of miRNA precursors. Mature miRNAs and miRNA stars are highlighted in red and blue, respectively. (B) Alignment of precursors. Mature miRNAand star sequences are underlined in red. (C) Schematic diagram of sense and antisense miRNAs and their potential target sites. Only one miRNA/target duplex proximal to CDS is presented (labeled with an asterisk). (D) Sense and antisense miRNAs target each other. All target sites were predicted using RNAhybrid2.2 and filtered with MirTif. The SVM score is higher than 1.0.
