Fig 1. Host defense against P. aeruginosa-mediated killing in liquid is mediated via different factors than infection on plates.

(A) Venn diagram of genes upregulated in Slow Killing (i.e., agar-based infection) and Liquid Killing (i.e., siderophore mediated intoxication). The number of genes in each category is presented and p-values (based on the hypergeometric distribution) are shown. (B) Lists of Gene Ontology (GO) groups overrepresented in the transcriptional responses against P. aeruginosa in Slow Killing (top) or Liquid Killing (bottom).
