Kinetic RT-PCR analysis of gene expression. cDNA was synthesized from total RNA from 14-day old seedlings treated with 25 μM PBI425 or 20% PEG 8000 for 4 h. Amplification of the housekeeping gene encoding polypyrimidine tract-binding protein1 (PTBpa, AT3G01150) was used as control to normalize expression data. All values represent the averages of three biological replicates, each analyzed three times (technical replicates) ± standard error. In cases where expression levels were too small to graph, values are indicated in writing. If no bar is visible and no value indicated, the analysis was not performed.
