+      Microarray expression data comparing cells without estradiol inducer, which express a TF at a very low level and post-induction, which express the TF at a high level by 15-30 minutes post induction. Contains many time points. Cells were grown in minimal medium with glucose in continuous-flow chemostats. In most experiments growth was limited by phosphate limitation.
