Induction of competence for genetic transformation by antibiotics: convergent evolution of stress responses in distant bacterial species lacking SOS?

Current Opinion in Microbiology, 2012
Bacterial transformation is a programmed process resulting in genetic transfer and diversity. It relies on the development of competence via regulatory circuits which are diverse and tailored to the particular lifestyle of each species. Despite this diversity, some species have been reported to trigger competence in response to antibiotics.

Functional consequences of inducible genetic elements from the p53 SOS response in a mammalian organ system

Experimental Cell Research, 2017
In response to DNA damage from ultraviolet (UV) radiation, bacteria deploy the SOS response in order to limit cell death. This bacterial SOS response is characterized by an increase in the recA gene that transactivates expression of multiple DNA repair genes. The current series of experiments demonstrate that a mammalian organ system (the cochlea) that

[SOS response of DNA repair and genetic cell instability under hypoxic conditions].

Radiatsionnaia biologiia, radioecologiia, 2011
The SOS DNA repair pathway is induced in E. coli as a multifunctional cell response to a wide variety of signals: UV, X or gamma-irradiation, mitomycin C or nalidixic acid treatment, thymine starvation, etc. Triggering of the system can be used as a general and early sign of DNA damage. Additionally, the SOS-response is known to be an "error-prone" DNA

The bacterial SOS response promotes the expression of the transposase encoded by IS CR mobile genetic elements

ABSTRACT Insertion sequences (IS) are widely involved in bacterial genomic plasticity by disrupting, adding, moving genomic sequences, or by activating or extinguishing gene expression. A specific family of IS, IS CR (for insertion sequence of Common Region), is thought to be ...
