| Highly expressed condition | (BC) Cultures were inoculated from frozen glycerol stocks and grown overnight in LB at 37°C. These cultures were thendiluted, plated onto LB plates, and incubated for 16 h at 37°C. Cells were harvested from plates containing individual colonies [BI] andfrom plates with confluen growth [BC]. |
| (dia5) 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]. |
| (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]. |
| (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 . |
| (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]. |
| (M40t90) 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]. |
| (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]. |
| (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. |
| (Sw) Exponentially growing cells were spotted on 1 % agar LB plates and incubated at 37°C. Swarming cells were collected after 16 hours. |
| (T2.30H) Anon-sporulating B. subtilis strain was grown in a modified M9 medium in batch culture (T. Hardiman, K. Lemuth, M. A. Keller, M. Reuss, M. Siemann-Herzberg, J Biotechnol 132, 359, Dec 1, 2007). Glucose was exhausted when the culture reached an OD600 of approx. 10 and this was designated T0 [T0.0H]. 7 samples were harvested at various times before glucose exhaustion [T-5.40H to T-0.40H] and 10 samples at various times after glucose exhaustion [T0.30H to T5.0H]. |
| Lowely expressed condition | (aero) 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. |

| (G135) Purified spores were obtained by growing cells in DSM medium (P. Schaeffer, J. Millet, J. P. Aubert, Proc Natl Acad Sci U S A 54, 704, Sep, 1965) at 37°C for 48 hours after which they were washed ten times in ice cold distilled waterover a period of 5 days. Purified spores were heat activated at 70°C in Tris 10 mM pH8.4 and germination was initiated by the addition of L-alanine 10 mM (A. Moir, J Bacteriol 146, 1106, Jun, 1981). After incubation for one hour at 37°C, the culture was diluted with an equal volume of 2X LBmedium and germinating cells were harvested at 135, 150 or 180 minutes after addition of L-alanine [G135, G150 and G180]. |
