Dynamics of metabolite adjustments to salt stress. Overview about the metabolic changes of Chlamydomonas upon salt treatment; [A] principal component analysis (PCA) visualizing the metabolic changes measured by GC/MS based metabolic profiling, [B] relative changes of metabolite levels in Chlamydomonas after 24 hours treatment with 100 mM NaCl compared to 24 h time point of the control. The colors indicate different classes of metabolites: red and pink, intermediates of glycolysis and TCA cycle; light blue; amino acids, gray; others. [C] The temporal behavior of the amino acids proline, putrescine, glutamate and ornithine is shown at all time points compared to control (0 h/0 mM).
