  1. a Sequence logos for the discovered motifs can be found in Additional file 1: Table S6
  2. b G indicates glucose, R ribose, X xylose. Notation G > R designates the group of genes that have higher expression during growth on glucose than on ribose; G ≈ X > R – the group of genes that has similar expression levels on glucose and xylose, which are higher than on ribose
  3. c q-value is an adjusted p-value, as given by tomtom tool from MEME suite [33]
