Graphical representation of changes in primary metabolite profiles of calli grown at different sucrose concentrations in the presence and absence of light. (a) Principal component analyses (PCA) applied to the primary metabolome set of 76 annotated and non-annotated (NA) metabolites analyzed using GC-MS. The data points are displayed as projections onto the two primary axes (eigenvectors). Variances explained by the first two components (PC1 and PC2) appear in parentheses; (b) Heat map of the 76 primary metabolites. The intensity of blue or red represents the value of the coefficient, as indicated on the color scale. Each column represents an average of four biological repeats. Four clusters were identified by different letters on the left
