Size profiling of small non coding RNAs and their homology to different RNA classes or to Transposable Elements (TE). The percentage of sncRNA reads is plotted as a function of their size (between 15 nt to 40 nt corresponding to the size range that has been selected from the gel for library construction), panels a, c O. nubilalis, panels b, d O. scapulalis, in green on corn, in red on mugwort. OnCor: On on corn, OnMug: On on mugwort, OsCor: Os on corn, OsMug: Os on mugwort. Panels a, b total reads, panels c, d unique reads. Panels e, f Pie charts representing the average % of reads (total counts from 2 replicates on corn for On (e) or Os (f)) mapping either to insect or plant miR precursors, or TE (Os TE copies) as expected for putative endo-siRNA or piRNAs, or mRNA, or tRNA, rRNA (18S and 28S RNAs) or mitochondrial genes
