Figure 4. Overview of differentially-expressed probe sets involved in the biotic stress response to inoculation with enteric pathogens and Gene Ontology analysis of over- and under-represented functional groups in the differentially-expressed probe sets.

Most of the differentially-expressed probe sets involved in response to inoculation with cocktails of S. enterica and E. coli O157:H7 play a role in signaling, secondary metabolites, hormone signaling, cell wall modifications, and pathogenesis-related (PR) proteins (A). Gene enrichment analysis using the AgriGO software platform indicates the functional categories over- and under-represented against the reference (B). (Note: the data for the enrichment analysis were normalized against the reference).
