Phenotypes of WT and OsIG1-RNAi inflorescences and spiklets. (A, B) WT spiklet (A) and (B) with two lodicules, six stamens and one carpel. The two empty glumes, lemma and palea were removed for clarity in (B). (C–K) OsIG1-RNAi spiklet. The lemma and palea were removed in (I) and (J) for clarity. (C) A RNAi spikelet with elongated empty glume (arrow). (D) The number of empty glumes increased in the RNAi spiklet. (E) An extra glume-like organ formed in the RNAi spiklet. (F) A spikelet with velum-like organs. (G) A spikelet with degenerated or malformed palea in inflorescences at stage In9; arrowhead indicates peduncle. (H) The florets with severe phenotypes showing no inner floral organs. (I) Lodicules were fused at the base and transformed into carpel-like organs. (J) One stamen is transformed into a stigma-like organ in an OsIG1-RNAi spiklet. (K) The OsIG1-RNAi ovaries were clearly swollen compared with WT (B). (L) Inflorescences at stage In9 of WT; arrowhead indicates peduncle. ca, carpel; dpa, degenerated palea; eg, empty glume; est, ectopic stigma; fi, filament; gl, glume-like organ; le, lemma; lo, lodicule; pa, palea; st, stamen; sti, stigma; vl, velum-like organ.
