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), a and c SfC, c and d SfR, in green on corn, in red on rice. CC: SfC on corn, CR: SfC on rice, RC: SfR on rice, RR: SfR on rice. a and b total reads, c and d unique reads. e and f Pie charts representing the average % of reads (total counts from 2 replicates on corn for SfC (e) or SfR (f)) mapping either to SfC or plant miR precursors, or TE (SfC TE copies) as expected for putative endo-siRNA or piRNAs, or mRNA (SfC OGS2.2), or SfC tRNA, SfC rRNA (18S and 28S RNAs)
