Gene ontology (GO) enrichment analysis of the transcriptomic response of the lettuce cultivars Green Towers, Lollo Rossa, and Red Tide at 1- and 7-days post inoculation with Escherichia coli O157:H7 (Ec) or Salmonella enterica ser. Typhimurium 14028s (Se). Heat map shows the absolute value of Log10p-values of significantly (p < 0.05) overrepresented GO terms. GO terms are grouped by functional categories listed in Dataset S4. Heatmaps and clustering were conducted using the heatmap.2 R package with default analysis settings. ROS = reactive oxygen species
