Size distribution of small RNA sequences.

<p>(A) Reads and unique sequence distribution in all the small RNA libraries. 24 and 21nt length reads are the most abundant reads among the small RNAs. (B) Size distribution of reads originating from leaf (dark grey) and stolon (light grey) tissues expressed as a percentage of total reads. 24 and 21nt length reads are dominant in both of the tissues; in stolon tissues there are more reads for 21, 23 and 24nt length.
