tRNA-derived fragments in planarian anterior and posterior regeneration. (A) Schematic describing the strategy for sequencing. (B) Percentage distribution of all small RNA populations across various time points of anterior and posterior regeneration. (C) Percentage distribution of small RNA reads mapping to tRNAs across planarian anterior and posterior regeneration. Small RNA reads were segregated into 18–24 nt and 25–35 nt. (D) Expression profiles of each tRNA-derived fragment population over time points of anterior and posterior regeneration shows divergent patterns.
