Fig. 6. Morphological features of Arabidopsis flowers: (left panels) wild type; (middle panels) ap3; (right panels) ap3; AFI::DEF viewed by SEM. (A-C) Overall morphology of young flowers. Some of the sepals and petals in the front have been removed. The arrow in C indicates a wild-type-like stamen in the transgenic flower. Bars,100 µm. (D-I) Outer (D-F) and inner (G-I) epidermal surfaces of second whorl organs. Bars, 20 µm. (J-L) Cross sections taken approximately in the middle of immature buds. Note the similarity of sub-epidermal petal cells (in whorl 2), and the presence of pollen in stamens (in whorl 3), in wild type (J) and in ap3; AFI::DEF (L). Bars, 100 µm. Numbers indicate the whorl.
