Gene module analysis using a weighted gene co-expression network analysis (WGCNA). (A) Hierarchical clustering diagram of the modules. (B) WGCNA of the genes with dominant expression in the two rice varieties after brown planthopper (BPH) infestation. Red indicates a positive correlation and blue indicates a negative correlation. The darker the color, the stronger the correlation. The numbers in parentheses represent significant P-values; the smaller the value, the greater the significance. (C) KEGG pathway analysis of the unique DEGs in the pink module. (D) Co-expression regulatory network analysis of the pink module.
