Fig. 1From: Deciphering modular and dynamic behaviors of transcriptional networksHierarchical and modular organization of the yeast transcriptional network. Genes are clustered into different modules. Some of the modules (e.g., protein biosynthesis) are organized in more than two hierarchical levels; large modules are composed of several smaller modules, giving a star-like topology.
