Involvement of cla-miR164 in inflorescence architecture development through targeted cleavage of ClNAM in Chrysanthemum lavandulifolium. (A–B) Expression changes of ClNAM and cla-miR164 during the capitulum developing from the top of C. lavandulifolium. (C–D) Expression changes of ClNAM and cla-miR164 in S6 reproductive buds of different heights in C. lavandulifolium. (E–F) Targeted cleave ability of cla-miR164 on ClNAM. (G) The targeting sites of ClNAM and sequences of cla-miR164 in C. lavandulifolium, CK: Control Check, Var: Variant. (H) Expression changes of cla-miR164, ClNAM, ClCUC2a/c in leaves of momentary overexpression cla-miR164. Note: The lowercase letters represent the significance of differences between lines; where the letters are different, there is a significant difference (P < 0.05).
