Effect of IBMX, pCPT-cGMP, SNAP, and DEA NONOate on Expression of Ammonium-Repressed Genes NRT2.1, AMT1.1, and AMT1.2 in Wild-Type Cells.
The effect of IBMX (A), pCPT-cGMP (B), SNAP (C), and DEA NONOate (D) on the expression of NRT2.1 and AMT1.1 and AMT1.2 was determined by real-time PCR. Conditions of the experiment were the same as in Figure 5 (see Methods). Black bars represent controls (set to 100%) without the added chemical; gray and white bars represent the concentrations of each chemical as indicated in each panel. The error bars represent the sd of three biological replicates.
