a. Known binding site of each transcription factor is based on SwissProt database; b. Biological process for each transcription factor is taken from GO and SwissProt; c. Activation conditions: AA, amino acid starvation; CC, cell cycle; DS, diauxic shift; END, early nitrogen depletion (< 8 hour); ES, all environmental stresses; H2O2, constant 0.32 mM H2O2 exposure; HOO, hypo-osmotic shock; LND, late nitrogen depletion (³ 8 hour); mHSdo, mild heat shock from 29°C to 33°C at various osmolarity; PHO, phosphate metabolism; SSC, steady state growth on alternative carbon sources; SST, steady state growth at various temperatures; YPD, YPD stationary phase.
