Highly expressed condition	(ferm) Cells were grown in a synthetic medium (E. Härtig, A. Hartmann, M. Schätzle, A. M. Albertini, D. Jahn, Appl Environ Microbiol 72, 5260, 2006) at 37 °C. For aerobic growth, an overnight culture was used to inoculate 100 ml of the synthetic medium to a starting OD578 of 0.05. The culture was then incubated in a 500 ml baffled flask with shaking at 250 rpm [aero]. Anaerobic growth was carried out (i) in the presence of 10 mM potassium nitrate (nitrate respiration) [nit]; or (ii) in the absence of 10 mM postassium nitrate (fermentative growth) [ferm]. The procedure for anaerobic growth was: medium was inoculated to an OD578 nm of 0.1 in flasks completely filled with medium and sealed with rubber stoppers. They were shaken at 100 rpm to minimize cell aggregation. These cultures were inoculated aerobically with an aerobically grown overnight culture. Anaerobic conditions were achieved in the stoppered flasks after a short time through the consumption of residual oxygen. Cells were harvested during the exponential growth phase.
	(LBstat) Cells were grown in Luria-Bertani medium (Sigma) [LB] at 37°C with vigorous shaking in flasks. Overnight cultures were diluted 2000-fold in fresh pre-warmed medium and samples were collected during the exponential [exp], transition [tran] and stationary [stat] phases of the growth cycle .
	(LPhT) Cells were harvested (i) during exponential growth in high phosphate defined medium [HPh]; (ii) during exponential growth in low phosphate defined medium [LPh] (J. P. Muller, Z. An, T. Merad, I. C. Hancock, C. R. Harwood, Microbiology 143, 947, Mar, 1997);and (iii) at three hours after the outset of the phosphate-limitation induced stationary phase [LPhT].
	(M0t90) Cells were grown in LB medium at 37°C with vigorous shaking. An exponentially growing culture (O.D.600 approx. 0.25) was divided: one culture acted as the control [no mitomycin C , M0] while mitomycin was added to the second culture to a final concentration of 40 ng/ml [mitomycin, M40]. Samples were harvested at 0, 45 and 90 minutes after mitomycin addition [t0, t45 and t90].
	(M40t45) Cells were grown in LB medium at 37°C with vigorous shaking.

	(M9stat) Cells were grown in M9 supplemented with glucose (0.3 %) at 37°C with vigorous shaking. The composition of the M9 minimal medium is (per liter): 8.5 g Na2HPO4.2H20, 3 g KH2PO4, 1 g NH4Cl and 0.5 g NaCl. The following solutions were individually sterilized and added (volumes per liter of medium): 1 ml 0.1 M CaCl2.2H2O, 1 ml 1 M MgSO4.7H2O, 1 ml 50 mM Fe-Citrate. Also added was 10 ml of a trace salts solution containing (per liter): 170 mg ZnCl2, 100 mg MnCl2.4H2O, 60 mg CoCl2.6H2O, 60 mg Na2MoO4.2H2O and 43 mg CuCl2.2H2O. Overnight cultures were diluted 2000-fold in pre-warmed M9 medium and samples were harvested during exponential growth [M9exp], at the transition phase [M9tran] and during stationary phase [M9stat].
	(nit) Cells were grown in a synthetic medium (E. Härtig, A. Hartmann, M. Schätzle, A. M. Albertini, D. Jahn, Appl Environ Microbiol 72, 5260, 2006) at 37 °C. For aerobic growth, an overnight culture was used to inoculate 100 ml of the synthetic medium to a starting OD578 of 0.05. The culture was then incubated in a 500 ml baffled flask with shaking at 250 rpm [aero]. Anaerobic growth was carried out (i) in the presence of 10 mM potassium nitrate (nitrate respiration) [nit]; or (ii) in the absence of 10 mM postassium nitrate (fermentative growth) [ferm].

Anaerobic conditions were achieved in the stoppered flasks after a short time through the consumption of residual oxygen. Cells were harvested during the exponential growth phase.
	(S1) Cells were grown in CH medium at 37°C and sporulation was induced by resuspension in warm sporulation medium as described by Sterlini and Mandelstam (J. M. Sterlini, J. Mandelstam, Biochem J 113, 29, Jun, 1969). The initiation of sporulation was designated T0, the time of resuspension. Samples were harvested at hourly intervals for 6 hours [S0 to S6] for the first set of experiments and for 8 hours [S0 to S8] for a second set of experiments.
	(S2) Cells were grown in CH medium at 37°C and sporulation was induced by resuspension in warm sporulation medium as described by Sterlini and Mandelstam (J. M. Sterlini, J. Mandelstam, Biochem J 113, 29, Jun, 1969). The initiation of sporulation was designated T0, the time of resuspension. Samples were harvested at hourly intervals for 6 hours [S0 to S6] for the first set of experiments and for 8 hours [S0 to S8] for a second set of experiments.
Lowely expressed condition	(BT) A fresh colony grown on an LB plate was used to inoculate 10 ml of LB and grown for 10 hoursat 30°C. This culture wasused to inoculate 10 ml of MSgg medium (S.S. Branda et al., J Bacteriol 186, 3970, Jun, 2004) and incubated with vigorous shaking. The cultures in MSgg were diluted to the same extent in 96 wells microtiterplates (5 μl for 1.5 ml of medium) and incubated without shaking at 30°C. Cells from the control cultures were harvested after 24 hours of incubation [BT]. Biofilms were harvested from 96 well plates after incubation for 36 hours [B36] and 60 hours [B60].
	(dia15) Diamide was added to an exponentially growing culture (OD600 approx. 0.6) at a sub-lethal concentration(0.5 mM) and growth continued at 37°C with vigorous shaking. Samples were collected 0, 5 and 15 minutes after diamide addition [dia0, dia5 and dia15].
	(Diami) Cells were grown in LB medium at 37°C. At OD540 of 0.3, the culture were divided into four subcultures and diamide 0.6 mM [Diami], paraquat 0.4 mM [Paraq], H2O2 0.1mM [H2O2] or no oxidative drug [Oxctl] were added to the medium. Samples were taken 10 minutes after addition
	(Etha) Cells were grown in a synthetic medium (J. Stülke, R. Hanschke, M. Hecker, J Gen Microbiol 139, 2041, Sep, 1993) with 0.2 % glucose as carbon source (Belitsky Minimal Medium/BMM) at 37 °C with vigorous shaking. Stress was applied to exponentially growing cultures at OD500nm of 0.4. Samples were harvested before stress [BMM]; after a rapid temperature up-shift from 37 °C to 48 °C [Heat]; after a temperature down-shift from 37 °C to 18 °C [Cold]. Ethanol stress was imposed by adding ethanol to a final concentration of 4 % (v/v) and cells were harvested 10 minutes after ethanol addition [Etha].
	(GM+45) A culture of LB medium was inocualted from a frozen glycerol stock of B. subtilis. After few hours at 37oC when the culture was growing exponentially, this culture was used to inoculate M9 minimal medium at several different dilutions usually in the range of 500- to 2000-fold. The dilution range was chosen to ensure that at least one of these M9 precultures had reached an OD600 between 0.5 - 1.0 after overnight incubation. These precultures were then used to inoculate 2.5 L of M9 medium in a 3.1 L KLF bioreactor (Bioengineering AG, Wald, Switzerland) to a starting OD600 of 0.03 – 0.05. Condiions in the bioreactor were rigorously controlled as follows: temperature was controlled at 37 °C; the pH was maintained at exactly 7.2 by automatic titration with 2.0 M KOH and 2.0 M H2SO4, and the dissolved oxygen tension was maintained above 50%. In each nutritional shift experiment cells were grown on the single substrate until the OD600 reached 0.50, at which point the second substrate was added instantaneously (4 g/L L-malate or 3 g/L glucose). The nutrient shifts performed were from glucose to glucose+malate [GM] and from malate to malate+glucose [MG] (Buescher et al., accompanying paper). Cell growth during the course was monitored throughout the experiment by measuring OD600.
	(H2O2) Cells were grown in LB medium at 37°C. At OD540 of 0.3, the culture were divided into four subcultures and diamide 0.6 mM [Diami], paraquat 0.4 mM [Paraq], H2O2 0.1mM [H2O2] or no oxidative drug [Oxctl] were added to the medium. Samples were taken 10 minutes after addition
	(Oxctl) Cells were grown in LB medium at 37°C. At OD540 of 0.3, the culture were divided into four subcultures and diamide 0.6 mM [Diami], paraquat 0.4 mM [Paraq], H2O2 0.1mM [H2O2] or no oxidative drug [Oxctl] were added to the medium. Samples were taken 10 minutes after addition
	(Paraq) Cells were grown in LB medium at 37°C. At OD540 of 0.3, the culture were divided into four subcultures and diamide 0.6 mM [Diami], paraquat 0.4 mM [Paraq], H2O2 0.1mM [H2O2] or no oxidative drug [Oxctl] were added to the medium. Samples were taken 10 minutes after addition
	(Salt) Cells were grown in Spizizen’s minimal medium (SMM) at 37 °C with vigorous shaking. Salt was added, to a final concentration of 0.4 M to an exponentially growing culture of cells at OD500 of 0.4. Samples were harvested before [SMM] and 10 minutes after [Salt] NaCl addition.
	(Sw) Exponentially growing cells were spotted on 1 % agar LB plates and incubated at 37°C. Swarming cells were collected after 16 hours.
