Highly expressed condition	(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].
	(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].
	(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].
	(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.

	(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
	(Heat) 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].

	(HiTm) Cells were grown in Spizizen’s minimal medium (SMM) (C. Anagnostopoulos, J. Spizizen, J Bacteriol 81, 741, May, 1961) with vigorous agitation. The control culture was grown at 37 °C [SMMPr]. For growth at high or low temperatures, pre-cultures were grown at 37 °C, diluted to an OD578nm of 0.1 and subsequently transferred to 51 °C [HiTm] and 16 °C [LoTm], respectively. For the growth at high salinity, the salinity of the medium was adjusted by adding NaCl (5 M stock solution) to produce a final concentration of 1.2 M [HiOs].
	(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].
