P. aeruginosa transcriptomic alterations during adaptation to the CF lung environment
Square colour indicates gene expression: up-regulation (red), down-regulation (green), undetermined (light grey), divergent according to studies (dark grey). (a) Gene expression in late isolates in comparison to related early isolates of P. aeruginosa . The 41 genes with a convergent pattern identified in at least four isolates were selected [12, 13, 83–85]. (b) Gene expression in clinical CF isolates in vivo (CF sputum, explanted lungs or zebra fish infection) in comparison to growth in vitro [91–94]. (c) Gene expression in PAO1 in vivo (murine infection model of acute pneumonia) in comparison to growth in vitro [95].

Genes annotated with an identical letter belong to the same operon.
Genes in bold respond to the following criteria: (i) convergent expression in CF late isolates in comparison to early ones, (ii) convergent expression in vivo in comparison to in vitro growth,and (iii) specific dysregulations in vivo in comparison to PAO1.
