RsbU-dependent σB activation in stationary phase by B. subtilis with novel RsbR combinations. B. subtilis strains BSH308 [ΔrsbRA1(Cm) ΔrsbRB1::kan rsbQ::ery SPβ ctc::lacZ] (▴), BSH311 [ΔrsbRA1(Cm) ΔrsbRB2 ΔrsbRD1::spc rsbQ::ery SPβ ctc::lacZ] (♦), BAR343 [ΔrsbRA1(Cm) ΔrsbRB1::kan ΔrsbRC1::ery rsbP::spc SPβ ctc::lacZ] (▪), BSH315 [ΔrsbRA1(Cm) ΔrsbRD1::spc rsbQ::ery SPβ ctc::lacZ] (✖), and BSH316 (ΔrsbRB2 ΔrsbRD1::spc rsbQ::ery SPβ ctc::lacZ) (×) were grown to stationary phase (indicated by the arrow) in LB. Samples were taken at the indicated intervals and assayed for σB-dependent β-galactosidase activity.
