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].
	(C30) Cellsgrown overnight on LB agar plates at 30°Cwere harvested and used to inoculate pre-warmed minimal medium at OD600 of 0.5 (D. Dubnau, R. Davidoff-Abelson, J Mol Biol 56, 209, Mar 14, 1971). After growth at 37°C with vigorous shaking, cells were diluted ten times in fresh pre-warmed minimal medium and samples were harvested after a period of 30 minutes [C30] , i.e. before maximal induction of competence, and after a period of 90 minutes [C90], i.e. when competence induction was maximal.
	(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].
	(G150) 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].
	(G180) 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.

	(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
	(LBGexp) Cells were grown in Luria-Bertani medium (Sigma) supplemented with glucose 0.3 % [LBG] 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 .
	(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
	(Sw) Exponentially growing cells were spotted on 1 % agar LB plates and incubated at 37°C. Swarming cells were collected after 16 hours.
Lowely expressed condition	(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].
	(Pyr) A 5 ml aliquot of LB medium was inoculated using frozen culture stocks. After a few hours growth at 37°C, precultures were prepared by inoculating 5 ml of M9 with this LB culture at several different dilutions usually ranging from 500- to 2000-fold. The dilution range was chosen so that one of these precultures had grown to and OD600 of 0.5 - 1.0 after overnight inculation. The chosen M9 medium precultures [at OD600 of 0.5 - 1.0] were used to inoculate 100 mL of M9 medium in 500 mL non-baffled shake flasks to an OD600 of 0.02. Filter-sterilized carbon sources were added separately to the medium M9 at following concentration: D-Glucose 3g/L[Glu], L-Malic acid 4.5g/L[Mal], L-Malic acid + D-Glucose 3 and 2g/L[M+G], D-Fructose 3g/L[Fru], D-Gluconate 4g/L[Glucon], Pyruvate 6g/L[Pyr], Glycerol 6g/L[Gly], Glutamic acid + Succinic acid 2 and 2g/L[G+S]. Where necessary, carbon source solutions were pH neutralized with 4 M NaOH prior to addition to the medium. Cells were harvested during the exponential growth phase.
	(S3) 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.

	(T5.0H) 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].
