Conserved protein-coding genes surround flanking miRNA genes. The chromosomal regions surrounding two miRNAs are displayed as vertical yellow lines. Each of the protein-coding genes nearby are shown as black horizontal lines, while the miRNA is displayed as a red horizontal line, and indicated by the arrow because of the resolution of the images. The green lines represent genes that are conserved according to BLASTN analysis. (A) miR159 family. (B) miR166 family. (C) miR156 family. (D) MPSS tissue expression for miRNA genes from miR166, miR159, and miR156.
