Figure 3

Protein-protein interaction (PPI) networks of the extracellular proteins differentially expressed in A. hydrophila under iron starvation condition. The gradient color indicates iTRAQ protein ratio (on a log2 scale), and size represents protein interaction frequency. Predicted extracellular proteins are displayed in yellow circles.
