  1. aFunction derived from B. cenocepacia J2315 [34].
  2. cChange in 16-h cultures of cepI mutant compared to 16-h cultures of K56-2 as determined by promoter fusion Subsin et al. 2007 [27].
  3. cChange in 16-h cultures of cepR, cciR or cepRcciIR mutants compared to 16-h cultures of K56-2 as determined by microarray analysis with at least two biological replicates (NC, no change).
  4. dPresence of a cep box motif was identified by Subsin et al. 2007 [27] for this gene.
