Genome sequences reveal adaptations in Pseudomonas aeruginosa after evolution under nutrient limitation, suggesting evolutionary mechanisms.
We report draft genome sequences of eight Pseudomonas aeruginosa strains, including four ancestral strains, two clinical and two environmental, and four derivative lineages evolved over 12 weeks of static culture in minimal nutrient medium. These genomes exhibited increased pigment production (pyocyanin), altered biofilm and motility phenotypes, reflecting adaptive genomic change.
