Transcriptional regulation within the glucose regulatory system. Transcript changes (horizontal) of all essential pathway members, those that upon deletion still behave like WT (“like WT”), as well as transcripts of pathway members categorised into the “high glucose” and “low glucose” group are depicted in the different mutants (vertical). Grey boxes indicate pathway members involved in the metabolic pathways. Colour scale and order of mutants (vertical) as in Figure 2. Transcripts (horizontal) of essential pathway members and members corresponding to mutants that behave like WT are ordered as derived from the hierarchical clustering. The transcript ordering of pathway members included in the “high glucose” and “low glucose group” is the same as for the mutants. The diagonal depicts the deleted genes.
