Weighted Gene Co-expression Network Analysis (WGCNA) of DEGs. A Cluster dendrogram of transcription factors based on expression levels in the five developmental stages (IN3, IN5, IN7, IN9 and IN11). Each branch represents a gene and each colour below represents a gene co-expression module. B Module-trait relationship analysis by WGCNA. Numbers in the squares presented the module-trait correlations (with corresponding p-values in parentheses). The color scale represents the module-trait correlations from –1 (blue) to 1 (red). The colour bar indicates expression and correlation levels from low(blue) to high (red). Panels IN3, IN5, IN7, IN9 and IN11 represent the different internodes stage, respectively
