Expression profiles of tRF-5s and itRFs across planarian anterior and posterior regeneration. (A,A′) Heat maps of candidate tRF-5s during anterior and posterior regeneration. We identified three groups of expressions. tRF-5s that are down-regulated over all regeneration time points, tRF-5s that are up-regulated in early timpoints of regeneration (3rs–1 d), and late time points of regeneration (3–7 d). (B,B′) Heat maps of candidate itRFs during anterior and posterior regeneration. We identified three groups of expressions. itRFs that are down-regulated over all regeneration time points, itRFs that are up-regulated in early time points of regeneration (3rs–1 d) and late time points of regeneration (3–7 d).
