摘　　要：Dear Editor,Reduction in plant height has been associated with yield increases and yield stability in a number of important crop species,such as wheat and rice[1].In these plants,dwarfing is mainly attributed to the inability to synthesize or respond to certain phytohormones,predominantly gibberellin(GA)[2].Ideal Plant Architecture 1(IPA1),an miR156 target gene,encodes SPL14 and it is able to bind directly to the promoters of multiple GA biosynthetic,signal,and deactivating genes in rice[3].Moreover,IPA1 loss-of-function mutants exhibit dwarf phenotypes[4].
