(A) A wild-type flower with two empty glumes (eg), lemma (le), palea (pa), two lodicules (lo), six stamens (st) and one gynoecium (arrowhead) with two stigmas (sti). A half of the lemma and palea were removed to show the inside of the flower. (B) A spw 1-1 flower. Stamens and lodicules are homeotically transformed into carpels (arrowheads) and palea-like organs (arrows), respectively. (C) A dl-sup 1 flower. The carpel is homeotically transformed into ectopic stamens (arrowheads). (D) A spw 1-1 dl-sup 1 flower with ectopic palea-like organs (arrowheads) and organs of unknown identity (arrows). The lemma and a half of palea were removed in B-D. (E-H) Floral diagram of (E) the wild-type flower, (F) the spw 1-1 flower, (G) the dl-sup 1 flower, and (H) the dl-sup 1 spw 1-1 flower. ra, rachilla. Bar: 1 mm.
