Global gene expression analysis by use of microarrays reveals massive and selective lipoprotein gene induction in mucoid P. aeruginosa. The experimental points represent merged expression data from three independent cultures run on three separate chips for each strain. Mucoid strain PAO578II carries the typical CF mutation mucA22, which causes mucoidy in P. aeruginosa. Gene expression in PAO578II was compared to that in the isogenic, nonmucoid, algU knockout strain PAO6865. Large crosses, lipoprotein genes induced in mucoid P. aeruginosa (P < 0.001). Diagonal lines delimit regions of ≥30-fold induction.
