In addition to PAO1 strain, we analyzed the intraspecific diversity of the Anr regulon by exploring the set of genes controlled by Anr in seven P. aeruginosa strains from diverse origins: three isolated from environmental habitats (MTB-1, YL84, SJTD-1) and four clinical isolates from chronic cystic fibrosis (CF) lung infections (LESB58, DK2, RP73, SCV202065) (Supplementary Table S2). Here, SMOX is linked to cystic fibrosis.
