Figure 5. The representative protein-protein interaction (PPI) networks based on proteins differentially expressed in response to R. nigricans infection.

The PPI networks were constructed by using the InParanoid database and String database according to GO and PANTHER biological processes, molecular functions, or KEGG pathways were integrated with the String database. The gene names of corresponding proteins are displayed in the networks. The red nodes represent those proteins that are differentially expressed between the non-inoculated and inoculated tomato fruit.
