Estimation of ropB mRNA half-lives in different growth phases

Growth phase	Estimated ropBmRNA half-life (min)
	qRT-PCR^a	Northern blotting^b
	qRT-PCR^a	Short transcript	Long transcript
Early exponential	2.2 ± 0.4	ND	ND
Mid-exponential	1.9 ± 0.2	1.2	0.5
Late exponential	1.9 ± 0.1	1.0	0.7
Stationary	17.7 ± 2.6	ND	ND

Half-life calculated from qRT-PCR analysis in Fig. 3A.

Half-life calculated from Northern blot analysis in Fig. 3B and C. ND, not determined.
