Fig. 4. AP1 and AG RNA accumulation patterns in hua1-1 hua2-1 and hua1-1 hua2-1 hen1-1 flowers. (A-H) AP1 RNA localization in hua1-1 hua2-1 (A-D) and hua1-1 hua2-1 hen1-1 (E-H) flowers of various stages. (A,E) Stage 3 flowers; (B,F) stage 6-7 flowers; (C,G) stages 9-10 flowers. (D,H) Mature flowers. Arrows indicate ectopic AP1 expression. In hua1-1 hua2-1 hen1-1 flowers, the ectopic AP1 expression is more precocious (arrows in E and F) and extensive (G and H). (I-L) AG RNA localization in (I,K) hua1-1 hua2-1 and (J,L) hua1-1 hua2-1 hen1-1 flowers. (I,J) AG expression in young flowers (stages indicated by numbers). (K,L) Stage 9 flowers. The arrow in L indicates a fourth whorl organ with little AG RNA. Se, sepals; St, stamens; C, carpels. Numbers in G and L indicate floral whorls. Scale bars, 50 µm.
