Homogeneity of Expression Levels in Strictly Coregulated Groups Coming From Transcriptome Data

Conditions	Two or more genes per complex regulon			Simple regulons
Group state
	on	off	Rejected	Fraction of homogeneous complex regulons	on	off	Total of regulons
Heat shock	21	30	20	0.72	27	31	129
Stationary phase	31	32	11	0.85	28	26	128
Anaerobic growth	30	26	16	0.78	32	26	130
Minimal medium	36	25	18	0.77	25	34	138

Homogeneity of expression within strict regulons was evaluated on the basis of a binomial probability using the Boolean values of expression in the four conditions tested.
