Expression of OsTMK in GA-treated stem sections. Stem sections were incubated in 50 μm GA₃ for the times indicated above the lanes. Shown are gel blots containing RNA (20 μg per lane) isolated from the 0- to 5-mm region above the second-highest node, which includes the intercalary meristem and the basal part of the elongation zone (A), 5 to 10 mm above the second highest node, which includes the elongation zone (B), and 10 to 20 mm above the second highest node, which includes the upper part of the elongation zone and the differentiation zone (C). All blots were hybridized to RL5, a constitutively expressed gene encoding a 5S rRNA-binding protein.
