Functional categories of genes in the EanI/R QS regulon. The figure represents those genes in the EanI/R regulon that were differentially expressed in the wild type strain, LMG 2665T between the two sampling points before QS and during QS. The 194 genes were grouped into different functional categories. The up regulated groups included those for flagella formation and flagella mediated motility, methyl accepting proteins and chemotaxis, redox sensing and cell adhesion. The groups with genes that were either up or down regulated included hypothetical proteins, transport, stress response, metabolism, cell wall synthesis, outer membrane proteins and regulators.
