Fig. 2.
P. aeruginosa strains PAO1 and PA14 have common yet distinct CF sputum essential genomes. Shown is the log2-transformed difference in transposon mutant abundance for every gene identifiable in a one-to-one ortholog mapping of strains PAO1 (x axis) and PA14 (y axis) after growth of these transposon libraries in MOPS-sputum. Gene essentiality calls are colored as shown, and the total number of genes per class is displayed in the appropriate color on the plot. N.E., not essential.
