Host-derived sRNAs in rice and small brown planthopper. (a, b) Size distribution of host-derived sRNAs in rice (a) and small brown planthopper (b). Host-derived sRNAs are 18–30-nt sRNAs with perfect match to the host genome minus those derived from structural RNAs. Numbers of sRNAs of the same size but with different 5′ terminal nucleotides were drawn in different colors. c, d 5′ terminal nucleotide frequency of host-derived sRNAs in rice (c) and small brown planthopper (d). e, f Volcano plot of differentially expressed sRNAs between mock-inoculated and RSV infected samples in rice (e) and small brown planthopper (f). Green dots represent differentially expressed unique sRNAs with significance cutoffs being fold change > 2 and adjusted p-value < 0.05
