Floral organ development influences plant reproduction and crop yield.The mechanism of floral organ specification is generally conserved in angiosperms as demonstrated by the ABC model.However,mechanisms underlying the development of floral organs in specific group of species like grasses remain unclear.In the genus Oryza (rice),a spikelet consists of a fertile floret subtended by a lemma,a palea,two sterile lemmas,and rudimentary glumes.To understand how lemma is formed,we identified a curve shaped l emma-distortion 1 (ld 1) mutant.
