FIGURE 2.

Differentially accumulated MIR genes in different tissues type and heat treatments. (a) Heatmap showing differentially accumulated MIR genes enriched in vegetative tissues with four sets of MIR genes: Set I, enriched in leaves and root; Set II, enriched in roots; Set III, enriched in stem and roots; and Set IV, enriched in leaves. (b) Similar to (a) except enriched in reproductive tissues, and with three sets of MIR genes: Set V, enriched in all reproductive tissues and stem/roots; Set VI, enriched in reproductive tissues; and Set VII, enriched in reproductive tissues and leaves. The key at right shows z‐score. B_2_4 indicates bud stage 1 with 2–4 mm in length, B_5_7 indicates bud stage 2 with 5–7 mm in length, and B_8_10 indicates bud stage 3 with 8–10 mm in length. (c) Smear plot showing differentially accumulated microRNAs (miRNAs) in reproductive bud stages: Upper track, bud stage 1 before (B_2_4) and after 14 days (B_2_4_F) of heat treatment; and in lower tack, bud stage 2 before (B_5_7) and after 14 days (B_5_7_F) of heat treatment
