Fig. S5. Ttranscripts of S. mutans with the highest fold-change in 10 h dual-species biofilms compared to single species biofilm. The bars are colored according to the assigned function of the corresponding gene. Activation of the competence related genes comS, comX and comY in the biofilm is much more pronounced than activation of comC, comD and comE that are also responsible for the activation of the bacteriocins. IGR: intergenic region.
