Figure 3.

Plants that are defective in respiration present a triple-response-like phenotype. (a) Median values of apical hook angle measurements are box-plotted for WT plants that were grown in the presence of 1 mM KCN or H₂0 as mock-control and mutant rpoTmp plants that were grown in the presence of 1 mM SHAM or DMSO as mock-control. N (measured in four independent analyses) corresponds to 178 for H₂O-treated WT plants and to 128 for KCN-treated WT plants. N (measured in two independent analyses) corresponds to 148 for DMSO-treated rpoTmp plants and to 85 for SHAM-treated rpoTmp plants. Details of box-plot representation are explained in figure 1b. (b) Images of etiolated mutant rug3 and atphb3 plants were taken under a dissection microscope. Scale bar corresponds to 1 mm. (Online version in colour.)
