Classification of analyzed sequence reads in libraries. We classified the analyzed sequence reads into 10 classes, including miRNA, mRNA, etc. As shown in Additional File 1, repeat elements accounted for less than 0.001% in all libraries and therefore were not included in the figure. The X-axis denotes the analyzed libraries. To simplify the figure, the same prefix of a library name is denoted by "~".
