Phenotypes of transgenic rice plants. A and B, Typical phenotype of an OsIPT overproducer 1 month after regeneration (OsIPT3 overproducer shown). C, Wild-type rice plant 1 month after germination. lb, Leaf blade; lj, lamina joint; ls, leaf sheath. D and E, Typical phenotype of OSH1 overproducer 1 month after regeneration. F, Scanning electron micrograph of shoots of OsIPT3 overproducer. Shoots were connected at their bottoms, indicating that axillary buds were successively grown. Leaf-like organs tightly overlapped each other and ectopic meristem was not observed on their adaxial surfaces (arrowhead). G and H, Scanning electron micrographs of leaf-like organs of OSH1 overproducer. Ectopic meristems (arrows) were occasionally formed on the adaxial surfaces of leaf-like organs (arrowheads). Scale bars, 2 mm (A, B, D, and E), 5 cm (C), and 250 μm (F–H).
