Fig. 7.
Flower primordium in an early bulge stage. Scanning electron micrographs (A, B), curvature plots (C, D), and side views of the reconstructed surface (E, F) showing the portion of periphery of the clv3-2 inflorescence shoot apex No. 4, different from the portion shown in Fig. 6. The side-view of the reconstruction shown in (G) was obtained from the replica of the Ler inflorescence shoot apex. The arrow in (E) points to the axil cells, of which the outer walls are folded. The cellular pattern on the SAM periphery in the reconstruction (F) is missing due to the strong steepness of this SAM portion. Bars=20 μm. (This figure is available in colour at JXB online.)
