WGCNA and module-trait correlation analysis. (a) Hierarchical cluster tree showing co-expression modules identified by the Dynamic Tree Cut method. Each leaf, that is a short vertical line, corresponds to a gene. Branches of the dendrogram group together densely interconnected constitute modules and are labeled with different colors. Genes with highly co-expression levels (correlation ≥ 0. 75) were merged into one module, 17 modules were obtained in total. (b) The number of genes in each module. (c) Correlations of pigment and NO3-N contents with WGCNA modules. Each row corresponds to a module. The columns correspond to phenotype traits. The color of each cell indicates the correlation coefficient between the module and traits. Red represents positive correlation and blue represents negative correlation. (d) The heatmap and bar plot with blue module eigengene
