Conserved noncoding RNAs: (A) miRNA, (B) snoRNA, and (C) tRNA. (A) The precursor miRNA transcript osa-miR394 is represented by the red bar with the arrow for the orientation and the mature miRNA sequence is highlighted in yellow color which is significantly more conserved in maize, sorghum, and Arabidopsis than the neighboring intergenic or intronic regions. The snoRNA (B) and tRNA (C) features are represented by arrowed bars in orange and blue, respectively.
