Figure 3.

Expression patterns of OSH15 at the AZ and internode. A, Schematic diagram of the OSH15 pro::GUS construct. B to E, GUS expression patterns at the AZ. Arrows indicate AZ. Bars = 200 µm. F to I, RNA in situ hybridization of OSH15. Arrows indicate AZ. Bars = 200 µm. J, Expression pattern of GUS in stems. The yellow line in the elongated region and the purple line in the meristem region indicate the positioning of cross sections. Bar = 2 mm. K and L, Cross sections of the elongated region (K) and the meristem region (L) at the indicated positions in F. E, Epidermis; LV, large vein; P, parenchyma cell; S, sclerenchyma cell; SV, small vein. Bars = 100 µm.
