Changes in Metabolite Composition during (De-)acclimation to High Light, Heat, and Cold

(A) Heatmaps based on Z-means of fold changes of SAMs and generated by hierarchical clustering according to Ward d2.

(B) Venn diagrams depicting shared or unique SAMs, comprising total numbers (left panel, “total”), or only the ones that show the same (up-up or down-down, “same trend”) or opposite (up-down or down-up, “opposite trend”) regulation polarities.

(C) Scheme summarizing the changes in concentration of metabolites involved in central metabolism in Arabidopsis. acc, acclimation; de-acc, de-acclimation; CBC, Calvin-Benson cycle; TCA, tricarboxylic acid cycle; Gluc, glucose; Fruc, fructose; P, phosphate; 3-PGA, 3-phosphoglycerate; PEP, phosphoenolpyruvate; 2-OAA, 2-oxaloacetate. Metabolites whose levels also changed under control conditions are indicated by ∗. Note that glycine levels decreased under control conditions.
