Tissue-specific expression of CEK3-GUS by histochemical GUS staining of transgenic plants harboring ProCEK3:CEK3-GUS (line 4). A to C, Time course of the GUS staining profile of germinating seeds at 1 (A), 2 (B), and 3 (C) d after planting. Seeds were stratified in sterile water for 1 d and then placed on MS-agar plates. D to I, Young seedlings at 4 (D), 5 (E), 6 (F), 7 (G), 10 (H), and 14 (I) DAG. J to N, Images of various plant tissues, including rosette leaf (J), cauline leaf (K), inflorescence (L), flowers at different developmental stages (M), and developing siliques (N). Scale bars = 200 μm (A and B), 1 mm (C, L, and N), and 2 mm (D–K and M).
