  • a For each mutant, the assigned gene number in the P. aeruginosa complete genome sequence (49) is provided. Insertion sites were identified by comparing the DNA sequence flanking Tn5-B21 with the complete P. aeruginosa genome sequence. In PAO-P8*, Tn5-B21 was inserted just upstream of gene PA4341. The lecA::lux expression value for each mutant is shown as percentages of that of the parent PAOI lecA::lux strain. Each value was calculated by dividing each 30-min reading of RLU per unit of OD495 from the LUCYI experiment by that for the PAOI lecA::lux parent strain.
