The metabolite correlation networks. (A) Significant metabolite correlation networks in WT plants (|r Met | ≥ 0.8, n = 17, p < 1.2 × 10-4). Each vertex corresponds to a metabolite or mass spectral tag (MSTs). The metabolites or MSTs with significant correlations are linked together. The colors of nodes represent the identified peaks (yellow circle), annotated peaks (red triangle) and MSTs (red square). The colors of the edges between nodes display the positive correlation (purple line) and the negative correlation (green line). (B) The common correlation pairs that are observed among WT, mto1, and tt4. (C) Expansions of the common network modules contain the following: (1) fructose-glucose, (2) cholesterol-campesterol and cholesterol-beta-sitosterol, and (3) succinate-fumarate and serine- glutamate.
