Ectopic expression of SPL/NZZ promoted stamen identity in the second floral whorl of the ap2-1 mutant. A, An ap2-1 flower showing leaf-like organs in whorl 1 and petals in whorl 2. B, An ap2-1 Pro35S:SPL/NZZ flower exhibiting narrow and up-curled petal-like organs in whorl 2. C, An ap2-1 Pro35S:SPL/NZZ flower showing all stamens in whorls two and three. D, SEM image showing a Pro35S:SPL/NZZ flower. E, SEM image exhibiting an ap2-1 Pro35S:SPL/NZZ flower with up-curled stamen-like organs in whorl 2. F and G, SEM images showing a stamen-like organ (F) as well as filament-like (arrows) and anther-like (arrowheads) epidermal cells (G; high-magnification view of F) in an ap2-1 Pro35S:SPL/NZZ flower. H and I, SEM images displaying an up-curled stamen-like organ (H) as well as filament-like (arrows) and anther-like (arrowheads) epidermal cells (I; high-magnification view of H) in an ap2-1 Pro35S:SPL/NZZ flower. J, SEM image exhibiting wild-type filament cells. Bars = 0.5 mm (A–D), 100 μm (E), 50 μm (F and H), and 10 μm (G, I, and J).
