Gene co-expression network of tomato seed development. a. Heatmap of module eigengene expression profiles throughout development in whole seeds and indicated seed tissues. Material was harvested at the indicated days after flowering. The corresponding fruit ripening stage is also shown. Module detection is explained in Additional file 1: Fig. S4. b.-d. Weighted gene co-expression network visualized using Cytoscape. b. Projection of expression modules, each colour corresponding to one module. c. Projection of preferentially expressed genes in the embryo (green), endosperm (orange) or seed coat (brown). d. Projection of seed preferentially expressed genes (red). ME, module eigengene
