Comparative transcriptome analysis of small noncoding RNAs in different stages of Trypanosoma brucei

tRNA-derived small RNA. (A) Small RNAs derived from different types of tRNAs. The top is SF stage, and the bottom is PF stage. (B) An example of small RNAs in the slender form derived from tRNA^Asp in relation to its secondary structure. The top is the length of tRNA^Asp-derived small RNAs. The middle is the position of small RNA mapped to the sequence of tRNA^Asp. The bottom is the sketch of tRNA structure and the cleavage site where small RNAs derived from.
