Total number of gene probesets modulated by drought stress or active PR in WT and Ljgln2-2 mutant plants.

	Experiment 1 Drought	Experiment 2 Active PR	Commonly affected
WT	2608	1480	187
Ljgln2-2	7915	6610	2173

The total number of gene probesets that changed significantly (p < 0.05) by drought was calculated by comparing the gene expression levels under drought conditions with the expression levels under control conditions (high CO₂ atmosphere, normal watering) as described by Díaz et al. (2010). The gene probesets that changed significantly (p < 0.05) by active PR conditions were identified by comparing the gene expression levels with a control under photorespiratory suppressed conditions (high CO₂ atmosphere, normal watering) as described by Pérez-Delgado et al. (2013). The column on the right shows the total number of gene probesets that were commonly elicited in the drought stress experiment and in the active PR experiment.
