Role of Extracellular DNA in Bacterial Response to SOS-Inducing Drugs
Antibiotics, 2023 The SOS response is a conserved stress response pathway that is triggered by DNA damage in the bacterial cell. Activation of this pathway can, in turn, cause the rapid appearance of new mutations, sometimes called hypermutation.

Response to ‘Not-so-simple setae’ [PDF]
Journal of Experimental Biology, 2011 In his Correspondence article ([p. 871][1]), DeForest Mellon, Jr argues that the type of seta in our report ([Monteclaro et al., 2010][2]) was erroneously identified. In response, we would like to make the following remarks.

Role of RecA and the SOS response in thymineless death in Escherichia coli. [PDF]
PLoS Genetics, 2010 Thymineless death (TLD) is a classic and enigmatic phenomenon, documented in bacterial, yeast, and human cells, whereby cells lose viability rapidly when deprived of thymine.
