FIG 5.

Volcano plot showing transcriptomic data for C. jejuni NCTC 11168 and the C. jejuni 11168ΔluxS (luxS mutant). Blue dots show differentially expressed data for C. jejuni NCTC 11168, and red dots show differentially expressed data for the luxS mutant. When dots shift more to the left or right, the differential expression (log₂ fold change) is stronger. Seven hundred and sixty-five genes were differentially expressed in the luxS mutant when normalized to C. jejuni NCTC 11168 (FDR, P ≤ 0.05). Among these, 354 genes were upregulated, and 402 genes were downregulated; Diff. expr., differential expression; DE, differentially expressed.
