Figure 6.

Effects of IAA and CHX on PsGA3ox1 transcript levels. Shown are PsGA3ox1 transcript levels in excised pea internodes cultured for 4 h on Murashige and Skoog medium containing the following: 1, no added IAA or CHX; 2, IAA (5 μg mL⁻¹); 3, CHX (14 μg mL⁻¹); 4, IAA (5 μg mL⁻¹) and CHX (14 μg mL⁻¹). The corresponding gel showing ribosomal RNAs stained with ethidium bromide is shown immediately below the northern blot to indicate the even loading of 5 μg of total RNA per lane.
