  • a Spots and averages are given in folds of activation or repression.

  • b Avg stands for the average of spots 1 and 2.

  • c +, genes up-regulated in the wild-type strain compared to the luxS mutant; −, genes down-regulated in the wild-type strain compared to the luxS mutant.

  • d The value −100 means that the gene was not expressed in the wild-type strain.
