Figure 4.

A partial rendering of the Arabidopsis whole-genome network. The illustrated network represents a union of all the shortest paths between each pair of the top 5% of the hubs in the whole-genome network (Supplementary Table S4). It contains 1556 genes and 22 073 interactions. The network topology is displayed using Cytoscape with the size of a node proportional to its degree and the intensity of its color proportional to its betweenness centrality. The largest and the darkest node in the bottom right-hand corner of the figure is PMDH2, a gene involved in photorespiration.
