Sequencing of miRNAs in three horse plasma libraries.

<p>(A) Venn diagram representing the numbers of miRNA species identified in the libraries. (B) Length distribution of miRNAs. The x-axis represents sequence lengths, and the y-axis the occurrence frequency of miRNA species for each given length. (C, D) Chromosomal location of miRNA genes. The x-axes represent chromosome number, and the y-axes the numbers of miRNA species (C) and reads (D) on the respective chromosome. Black and gray bars represent sense and antisense strands, respectively. For (C) and (D), data are shown as mean ± S.D. (n = 3).
