Plant hormone gibberellin (GA) promotes juvenile-adult phase change in higher plants. To confirm the functions of GA in rice, I used dwarf mutant d18-dy. d18-dy is a loss-of-function allele of D18, which encodes GA3ox2. d18-dy mutant exhibited long juvenile phase in morphological traits such as the size of the shoot apical meristem (SAM), shape of leaf blades, presence or absence of midribs and node-internode differentiation in stem. In contrast, expression patterns of juvenile-adult phase change markers miR156 and miR172 were similar between wild type and d18-dy. In addition, d18-dy mutation and GA did not affect expression levels of downstream genes of miR156. GA does not function upstream of miR156 in juvenile-adult phase change.
