RISC-bound small RNA sequencing provides insights into guide-strand selection and siRNA trimming and tailing following insecticidal dsRNA delivery
RNA interference (RNAi) offers a sequence-specific approach to pest control. In insects, Dicer-2 processes double-stranded RNA (dsRNA) into small interfering RNA (siRNA) duplexes, from which the RNA-induced silencing complex (RISC) retains a guide strand. However, how the sequence of delivered dsRNA shapes the RISC-bou...
