From: Non-essential genes form the hubs of genome scale protein function and environmental gene expression networks in Salmonella entericaserovar Typhimurium

Figure 4

Nodes degree distribution -P( k ) represents the probability that the number of links per node is equal to k - of the genes connected to environmental stresses, growth stage or immobilization condition in the environmental Network 2 (A) and of the genes connected to metabolic pathways and cellular roles in the S . Typhimurium genome scale Network 3 (B). Distributions followed the power law indicating the existence of highly connected genes or hubs in both networks.
