Analysis of small RNA reads and conservation of homologous miRNAs.

<p>(A) The sequence length distribution of small RNA read tags in Sf21 cells showed majority of the population at 20 nt, a typical length of mature miRNAs followed by the read lengths around 27 nt which could be putative piRNA sequences. (B) Percentage of known miRNAs from <i>Spodoptera frugiperda</i> with homologs from other insects; <i>B. mori, D. melanogaster, T. castenum, A. aegypti, A. gambie</i> and <i>C. elegans</i>.
