WGCNA analysis to identify key candidate genes involve in maize defense a Cluster dendrogram and network heatmap of genes subjected to co-expression module calculation; b Sample dendrogram and module trait heatmap of each time point; c Hierarchical clustering presenting modules having co-expressed genes. Each leaflet in the tree corresponds to an individual gene; d Module-trait associations based on Pearson correlations. The color key from green to red represents r2 values ranging from − 1 to 1
