Figure 2From: Phylophenetic properties of metabolic pathway topologies as revealed by global analysisThe distribution of P-values in differentphylogenetic categories. The Penriched-values and Pdepleted-values were calculated by using the equation 1 and equation 2 (see Methods), measuring whether a pathway specific subset was enriched in or depleted of organisms from a particular category (only P-values less than 0.05 are shown).Back to article page
