Fig. 6

Correlation network of DEGs and DAMs. The genes are represented by green squares with labels, whereas the metabolites are represented by blue ellipses with labels. Hubs are indicated in orange, with intergroup hubs containing a yellow border. Edges link highly correlated compounds. Modules of compounds are indicated by circles. Only edges corresponding to elements of the topological overlap matrix (greater than 0.55) are shown, both within and between modules; pink and blue edges indicate positive and negative correlations, respectively. Only one negative correlation was detected
