Comparison of colony morphology of TBCF10839 and PAO1 transposon mutants that are inserted into homologous genes ^#.

#TBCF10839 homologues are 99.8% or more identical in sequence with the respective PAO1 genes. *Morphotype: A, shiny autolysis; B, white colony on blood agar and iron supplemented media, on Congo red agar the colour is concentrated in the center of colony; C, light rose or colourless on Congo red agar; D, autolysis, but no shine; E, non mucoid structure at room temperature; F, orange pigment in the center of colony; G, small colony size. **PAO1 mutants were provided by the University of Washington Genome Center “Pseudomonas aeruginosa PAO1 mutant collection” (http://www.genome.washington.edu) [84]. +One PAO1 transposon mutant; ++Two PAO1 transposon mutants with an insert at the 5′ end (mutant 1) or at the 3′ end (mutant 2) of the gene.
