puchi Mutant Flowers Have Rudimentary Bracts at the Base of Their Pedicels.

(A) Scanning electron micrograph showing the base of the wild-type pedicel.

(B) Scanning electron micrograph showing the base of the puchi-1 pedicel. puchi produces a flat leaf-like organ (arrow) flanked by a pair of pin-shaped projections (only one is visible in this image; arrowhead).

(C) GFP expression of the enhancer trap line E1238 is detected in the stipule of the wild-type cauline leaf.

(D) GFP expression of the enhancer trap line E1238 is detected in the pin-shaped projection of the puchi-1 flower.

le, leaf; st, stipule; ped, pedicel; pro, pin-shaped projection. Bars = 100 μm.
