Figure 2From: Genes encoding hub and bottleneck enzymes of the Arabidopsismetabolic network preferentially retain homeologs through whole genome duplicationAnalysis of WGD-enzymes in metabolic network. (A) Comparison of three topological centralities between WGD-enzymes and the other enzymes. (B) Sub-network of WGD-enzymes. Dots represent enzymes and the lines represent the interactions among enzymes. (C) The distribution of IBWEs in 1000 randomization simulations. The arrow on the right hand side represents the observed number of IBWE.Back to article page
