- November 2011
- Locke et al. demonstrate how the SigB-dependent general stress response is controlled by signals using stochastic pulse frequency modulation through a compact regulatory architecture.
- Relevant SubtiWiki pages: Michael Elowitz, SigB, General stress proteins (controlled by SigB)

- October 2011
- Richards et al. identify the nudix hydrolase RppH as the pyrophosphohydrolase that triggers 5'-exonucleolytic degradation of mRNA by RNase J1 in B. subtilis.

- September 2011
- A series of papers deals with RNA processing and degradation in B. subtilis. Three papers establish that RNase Y is the functional equivalent of RNase E from E. coli. Moreover, the role of RNase J1 in endonucleolytic cleavage of the trp leader mRNA is demonstrated.

- August 2011
- Chi et al. demonstrate that S-bacillithiolation of the repressor OhrR and of four enzymes of the methionine biosynthesis pathway protects the B. subtilis cell against hypochlorite stress.

- July 2011
- Domínguez-Escobar et al. from Rut Carballido-Lopez' lab and Garner et al. report that movement of actin-like filaments is driven by the peptidoglycan elongation machinery. Both papers suggest that the MreB-like filaments serve to restrict the mobility of the peptidoglycan synthesizing machinery

- Domínguez-Escobar et al. from Rut Carballido-Lopez' lab and Garner et al. report that movement of actin-like filaments is driven by the peptidoglycan elongation machinery. Both papers suggest that the MreB-like filaments serve to restrict the mobility of the peptidoglycan synthesizing machinery
