FIG 3.
Biofilm formation of isogenic transposon mutant strains. Relative biofilm formation of isogenic JE2 transposon knockouts in the indicated genes, normalized to biofilm production of the parental JE2 strain (red line). Error bars indicate standard deviation from at least four separate measurements. * indicates a P value of <0.05 and ** indicates a P value of <0.01 by two-tailed t test against the parental strain.
