Promotion of growth by elevated carbon dioxide is coordinated through a flexible transcriptional network in Arabidopsis

Figures & data

Figure 1. Expression pattern of PREs, PIFs and BR-related genes in shoots of Arabidopsis plants treated with PAC and/or GA₄₊₇ grown at 350 (left) or 750 (right) µmol CO₂ mol^-1 as determined by quantitative RT-PCR. The color scale represents the Log2 fold change values of expression changes compared with control (blue, reduced; yellow, increased). For plants treated at ambient [CO₂], non-treated plants were used as control. For untreated plants at high [CO₂], the relative expression is shown as compared with ambient [CO₂] while expression data for plants treated at high [CO₂] were normalized to non-treated plants at elevated [CO₂]. Data represent means of three independent biological replicates. Heatmap was generated with the MultiExperiment Viewer (MeV) software (www.tm4.org/mev). AGI codes: PRE1 (AT5G39860); PRE2 (AT5G15160); PRE4 (AT3G47710); PRE5 (AT3G28857); PRE6 (AT1G26945); PIF1 (AT2G20180); PIF3 (AT1G09530); PIF4 (AT2G43010); PIF5 (AT3G59060); PIF6 (AT3G62090); PIF7 (AT5G39860); BZR1 (AT1G75080); BZR2 (AT1G19350); IBH1 (AT2G43060); ARL (AT2G44080); DWF4 (AT3G50660); BLH1 (AT2G35940).
