Mean expression of high-centrality transcription factors identified in module 2. Expression values are variance stabilized counts, biological replicates were summarized by their mean value. The x-axis represents the soil hydration. Data points “30%7 d”, “Collapse”, “C2d” and “Rehydrate” represent seven days of continuous drought at 30% hydration, collapse in function of photosynthesis and transpiration (indicating severe dysfunction), continued collapse after two days and finally re-hydration to 80%.
