#Description and putative function of the selected genes are based upon the published S. mutans database.
*, The levels of expression are presented as copy numbers of the respective transcripts per µg of total RNA.
@, Fold-change is defined as level of expression in the Rex-deficient mutant TW239 relative to those of the wildtype UA159, with a – representing down-regulation.
