Fig. 4. Weighted gene coexpression network analysis (WGCNA) of the identified genes in developing C. oleifera seeds.

A Gene dendrogram obtained by clustering the dissimilarity based on consensus topological overlap, with each tree branch constituting a module and each leaf representing one gene. Each colored row indicates a color-coded module that contains a group of highly interconnected genes. B Heatmap plot of topological overlap in the gene network. Darker squares along the diagonal correspond to modules. C Module eigengene physiological indexes and sample correlations. The numbers in colored rectangles represent gene numbers in the module. The color scale bar on the right shows the correlation range from negative to positive
