Transcriptional regulation among transcription factors. (a) Regulatory network among the transcription factors in the cell cycle condition. Each arrow represents transcriptional regulation. Two transcription factors linked by each colored arrow form an FFL group with the genes that are enriched in some specific functional category. The colors of the arrows imply the enriched functional categories. The networks in the two stress conditions are shown in Additional data file 9. (b) Condition-specific FFL groups. Each gray ellipse represents the overlapped target genes of the two transcription factors in an FFL group. Only selected FFL groups are shown (see Additional data file 10 for the complete list of the enriched functional categories of the FFL groups).
