Identification of sRNA 5′ and 3′ ends by Deep RACE.

<p>Blue lines show the number of 5′ RACE reads mapped to respective genome, while red lines show the number of 3′ RACE reads. The coordinates with the highest number of mapped reads (the peak) indicate the likely 5′ and 3′ ends of sRNAs and are labeled in the figure. The orange arrow under the chart shows where the Northern probes base-paired and the blue arrows are the adjacent annotated coding regions. Results for other sRNAs can be found in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0079411#pone.0079411.s004" target="_blank">Figure S4</a>.
