Differential expression of genes in response to the Zn²⁺ depletion of the ΔznuA strain.

RNA sequencing of P. aeruginosa PAO1 and the isogenic ΔznuA deletion strain was used to determine relative gene expression (expressed as log₂-fold change). Each green dot represents a gene, with each gene distributed on the x-axis in accordance with locus tag numbering for PAO1. Genes more highly expressed in the ΔznuA strain are present above the x-axis, with those below the x-axis expressed at a lower level in the ΔznuA strain. Genes of interest are annotated with their putative or characterised functions.
