Overview of expression data analyzed in this study.

Of the 11 gene expression data sets for which we predict and discuss growth rates, four are previously unpublished; excerpts of this data relevant to the growth rate analysis are provided in Tables S1, S2, S3, S4. These data span various experimental conditions, dual- and single-channel expression array platforms, batch and steady-state growth regimes, and three species of yeast. Under these varied conditions, our growth model predicts instantaneous growth rates and provides insight into regulatory mechanisms for growth homeostasis.
