| Highly expressed condition | (dia0) 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]. |
| (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]. |

| (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 |
| (S0) 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 | (C90) 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. |
| (Gly) 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. |
| (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]. |
