KEGG enrichment analysis of the key modules. (a) KEGG analysis of four temporally specifical modules including blue, red, turquoise, and yellow modules. The top 20 terms in different modules were visualized—if the enrichment result in a module were less than 20, all the terms would be showed. (b) The scatterplot of module membership (MM) vs. gene significance (GS) of the four modules in their associated periods, respectively.
