Gene co-expression network analysis for genes expressed in stems across growth timepoints for genotypes Neva and I-214. a Clustering dendrogram of all expressed genes together with assigned module colors. b The correlation between modules. Each row and column correspond to a module eigengene. The table is color-coded by the correlation according to the color legend. c The expression patterns of eigengene in modules. d The module–trait associations. Each row corresponds to a module eigengene, column to a trait. Each cell contains the corresponding correlation and p-value. The table is color-coded by correlation according to the color legend. e A scatterplot of gene significance (GS) for genotype vs module membership (MM) in the module red. There is a highly significant correlation (Cor = 1, p < 1e-200) between GS and MM in this module, illustrating that genes highly significantly associated with genotype trait also are the most important elements of modules associated with the trait. The red points represent transcription factors, and the grey ones are other genes in the module red. f The heatmap for the enrichment of genes in modules for GO terms from the cell wall, hormone, carbohydrate metabolism, cell activity, transport, light, and the response of defense and stress
